Mesohippus

Mesohippus was a small primitive species of horse that lived in the North American continent during the Eocene and Oligocene. It looked much like horses of today in most features, except for its hoofed feet, each which had three toes instead of the single toe of modern horses and its small size, around the size of a German shepherd dog. Mesohippus was an important evolutionary milestone, as it developed many features of modern day horses such as longer legs for greater speed. The only defense Mesohippus had was its speed and stamina to escape predators such as Hyaenodon and nimravids, but despite this it was a common prey item. Mesohippus was a widespread and very successful animal in its time and Mesohippus fossils are very common.

The Mesohippus is a wonderful animal for younger visitors who will find it both adorable and approachable.

### Mesohippus' History in Mesozoica

Mesohippus was added to the game by a Kickstarter Backer who felt that the game could have more mammals in the game. The model was unveiled on January 2, 2016.
Gigantoraptor

Gigantoraptor is a large therapod from Late Cretaceous Mongolia. This dinosaur is part of the caenagnathidae family and is significant in being the largest. While most other members, such as the famous Oviraptor, are quite small, reaching about the size of a goat, Gigantoraptor is almost the same size as Albertosaurus. The diet of Gigantoraptor, as well as that of other members of its families, is a mystery. Originally it was thought, due to the discovery of an Oviraptor crouched in a nest of what were believed to be Protoceratops eggs, that the family were egg thieves. However these eggs later discovered to be Oviraptor eggs, which were being guarded by one of their parents. Many speculations have arouse from the odd beaks and the four pairs of teeth of some of the more primitive members. These theories include that the dinosaurs fed on nuts or shells and used their beaks to crack them open or that they were fruit eaters or that they used their beaks to rip open carcasses and were scavengers. Evidence for both carnivorous and herbivorous diets have been found; an Oviraptor skeleton with the bones of a lizard in its stomach and another with gastroliths, so perhaps they were omnivorous or each species prioritized a certain diet. Whatever their diet, the caenagnathidae were most certainly specialized feeders and among some of the most bird like of dinosaurs.

Gigantoraptor will astonish many visitors, especially those expecting large slow scaly beasts. While it may be mistaken for a bird, Gigantoraptor's huge size, unique appearance and feeding patterns (whatever they may be) will prove a fascinating exhibit.

### Gigantoraptor's History in Mesozoica

Gigantoraptor was added by a Kickstarter backer on April 20, 2016, making it one of the largest carnivores in the game but sadly never added as Mesozoica ceased development presumingly after April 2018
Cave Lion

Panthera Leo Spelaea, or the Cave Lion is a large feline from the Pleistocene era. A large species of feline, the Cave Lion is a sub species of the modern African lion, Panthera Leo) which migrated northwards during the earlier half of the Pleistocene era as the equator became drier with the onset of the ice age. Some traveled across the Bering Strait landbridge, or Beringia to become the American Lion, Panthera Leo Atrox. The Cave Lion was the largest predator of Eurasia during the Pleistocene and was big enough even to tackle Cave Bears. Smaller predators such as Homotherium and Crocuta Crocuta Spelaea (the Cave Hyena) preferred to hunt on open plains, while Cave Lions roamed densely forested areas where they could ambush prey such as deer. As the Pleistocene drew to a close, forests replaced the vast grasslands where large herbivores such as the Woolly Mammoth once roamed. The forests would have benefited the lions, but new predators such as wolves and most notably humans began to compete with the lions by hunting the same prey. Humans had a distinct advantage over the cave lions with tools and intelligence to solve problems and adapt to different situations, while wolves required less food than the lions. Eventually the lion populations started to decline, but small populations in south east Europe may have survived for another ten thousand or so years and may have influenced many beasts from Ancient Greek mythology such as the enormous Nemian Lion, Chimera and Griffon. Cave lions appear on prehistoric art along with mammoths, woolly rhinos, wild horses, aurochs and other animals. The lions were a constant danger to prehistoric peoples and lion could easily kill a single human.

Cave lions are impressive Ice Age mammals with their great size and strength. They are sure to be a welcomed addition to any Pleistocene display or themed area, however do not take them lightly. While they are nowhere near as huge as a Tyrannosaurus, they are still formidable and powerful creatures.

### Cave Lion's History in Mesozoica

Panthera leo spelaea, or the Cave Lion, was announced as a Kickstarter Backer Choice with a model on December 21, 2015, later being edited on June 3, 2016.
Iguanodon

Iguanodon is a familiar and very successful herbivore from Early Cretaceous, Europe. Iguanadon is famous for being one of the very first dinosaurs to be named in 1822 by Victorian biologist Richard Owen, along with Megalosaurus and Hylaeosaurus. Iguanodon has a long history of reconstructions and interpretations; from a giant rhinoceros like iguana to a kangaroo like posture until finally it was correctly reconstructed as a mainly quadrupedal animal that occasionally could rise on its hind legs when needed. A distinctive feature of Iguanodon is the spike located on the thumbs of the forelegs. These would have been used both as a tool to reach up to high branches and also as a weapon to fend off predators.

Iguanodon fossils have been found in Belgium, Spain, The United Kingdom; especially in the fossil rich Isle of Wright and Germany, with possible fossils also found in North America and Northern Africa, however the latter pair may be different species. An Iguanodon species found in Mongolia has now become the genus Altirhinus. Iguanodon in Wessex Formation on the Isle of Wright lived alongside fellow herbivores Hypsilophodon, Polacanthus. Hylaeosaurus and the carnivores Neovenator, Baryonyx and Eotyrannus. The main threat of Iguanodon came from Neovenator, the largest predatory dinosaor of the Wessex Formation and the largest found so far in the UK. This powerful carnivore could tackle full grown Iguanodon. Eotyrannus being much smaller would be no threat to a full grown Iguanodon, but may have preyed on younger individuals or in packs taken down weaker Iguanodon. Baryonyx probably never hunted Iguanodon, but may have scavenged corpses; as seen by Iguanodon bones being found in Baryonyx stomachs.

Iguanodon is a relatively popular dinosaur, for both its contributions to science and staring in many films and television shows, such as Walking with Dinosaurs and the Disney movie Dinosaur. It may not be as eye-catching as a Tyrannosaurus, but Iguanodon will still make for a wonderful addition for herbivore communities.

### Iguanodon's History in Mesozoica

Iguanodon was first shown on the original master list of the old Mesozoica, but a model wasn't shown until July 5, 2015 with Megalosaurus and Hylaeosaurus, the first three dinosaurs to have ever been discovered. A second skin was shown on a size chart with several other dinosaurs.
Giganotosaurus

## Giganotosaurus Carolinii

Giganotosaurus is a huge carnivorous dinosaur from Late Cretaceous Argentina. Giganotosaurus is so far the largest carnivorous dinosaur, and to an extent land carnivore, ever discovered, although it is rivaled by Carcharodontosaurus and Mapusaurus, both of which are part of the carcharodontosauridae family and are related to Giganotosaurus. Giganotosaurus is recognizable by its massive sloping head. The skull showed well developed olfactory systems, meaning the dinosaur had an excellent sense of smell and a very powerful bite. The teeth of Giganotosaurus, as well as other carcharodontosaurids are flat and serrated and could not crush bone. Giganotosaurus and its relatives targeted large titanosaurs such as Argentinosaurus, who's bones would have been too strong to crush, so instead Giganotosaurus would aim for vulnerable points, biting at the ankles of the giants to weaken them to the point where they would collapse and then the Giganotosaurus would feed at its leisure. Giganotosaurus would also have no trouble tackling smaller animals such as rebbachisaurid dinosaurs, except for perhaps tiny ornithopods like Gasparinisaura which could outrun and out maneuver the giant.

Giganotosaurus made headline news in around the world in 1993 and later in 1995 when it was named; the current largest predatory dinosaur at the time, Tyrannosaurus had been dethroned. Ever since then Giganotosaurus has gained a massive surge in popularity, staring in television and many video games. Giganotosaurus is a spectacular dinosaur that will inspire awe and even dread in many visitors, but will excite fans of carnivores immensely.

### Giganotosaurus' History in Mesozoica

Giganotosaurus was one of the first dinosaurs to have been added to the game. This is largely due to it being the largest land carnivore to have been discovered so far. There are currently 2 models for Giganotosaurus.
Deinocheirus

Deinicheirus is a large dinosaur from Late Cretaceous Mongolia. It is a relative of Gallimimus and other ornithomimosaurs, but instead of sharing their sleek builds designed for speed, Deinocheirus has a bulky body and is the largest of the ornithomimosaurs. It is also more closely related to more primitive members of the family like Garudimimus and Beishanlong, rather than the more advanced species such as Gallimimus. Deinocheirus lived in swampy areas of Mongolia and this has hinted at its diet. It shared its home in the Nemegt Formation with many other dinosaurs, including the Mongolian subspecies of the hadrosaur Saurolophus, the tyrannosaurids Tarbosaurus (teeth marks on Deinocheirus that have healed suggests Tarbosaurus was its main enemy) and Alioramus, the pachycephalosaurids Homalocephale and Prenocephale, the ankylosaurid Tarchia, fellow ornithomimid Gallimimus and Therizinosaurus.

The history of Deinocheirus in science, like Spinosaurus and Iguanodon has been one of multiple reconstructions, however those of Deinocheirus were between two extremes. The first and for a while only fossils of Deinocheirus unearthed in 1970 were a pair of huge arms measuring nearly 8 feet (2.4 meters) long and with clawed hands. It was initially believed Deinocheirus was some sort of super predator, using its huge arms and hands to eviscerate large animals and snatch smaller prey. It appeared in many dinosaur books at this time, usually with a photo of its famous arms with a person standing next to them for size ratio and the dinosaur attained a great deal of popularity in the 1970s and 80s. Later in 2013, two more Deinocheirus skeletons were found, giving a clearer picture of what this animal looked like. The skull showed the dinosaur had a beak similar to a hadrosaur's and no teeth. Markings where the muscle connected to the jaw, may indicate Deinocheirus had a pelican like pouch. It also had a humped back similar to a camel's and a bulky body. Fish scales and gastroliths found in the stomach region suggest Deinocheirus was an omnivore, eating fish and plant matter.

Deinocheirus is a very interesting animal and a herd of them can attract many visitors. Deinocheirus will be most at home in a swampy or delta environment with plenty of fish and vegetation for its needs. It can make a prominent member of an Nemegt based biotope exhibit, with Gallimimus and Therizinosaurus.

Deinocheirus' History in Mesozoica

Deinocheirus was first announced as a creature that is being added to the game on July 27, 2015. What makes this dinosaur stand out from the others is its unique pelican-like skin that came with the dinosaur.

The initial animations for Deinocheirus were shown on August 18, 2015. On April 29, 2016, another skin was shown that was chosen by a Kickstarter Backer.
Corythosaurus

Corythosaurus is a large herbivorous dinosaur from Late Cretaceous North America. It is a member of the hadrosaurid family, like Maiasaura, Parasaurolophus and Edmontosaurus. Like Parsaurolophus, Corythosaurus has a hollow crest on its head. Unlike the long arching crest of Parasaurolophus, Corythosaurus' crest is circular and compact. The crest would have been used for amplifying the calls of Corythosaurus and as a display to mates. The sounds Corythosaurus made were probably different to those of Parasaurolophus, so sound may have been used to identify and keep in touch with herds, much like how whales use sound today. Corythosaurus like other hadrosaurs could raise on its back to legs when running or reaching for food higher in the trees. The beaked mouths of Corythosaurus and other hadrosaurs at the time are shaped differently, with some like Corythosaurus' being narrower, suggesting these species fed on different types of plant material and so competition for food was averted.

Corythosaurus makes for a wonderful edition to herbivore communities, including those with other hadrosaurs. The sight of their crests and the sounds of Corythosaurus calling to herd members makes for a visual and audible treat.

### Corythosaurus' History in Mesozoica

Corythosaurus originally appeared in Jurassic Park III and Jurassic Park: Operation Genesis, making it a must-have for the dinosaur community. It was revealed on January 15, 2016 as a Kickstarter Backer choice.
Dromaeosaurus

Dromaeosaurus is a small carnivorous dinosaur from Late Cretaceous North America. It is a very poorly understood dinosaur, having only one fossil specimen discovered so far which includes part of the skull and foot. A full reconstruction was only possible through study of more well known dromaeosaurids such as Velociraptor. The main distinguishing feature of Dromaeosaurus is the rather larger and heavy skull compared to those of other dromaeosaurids, suggesting it relied more on its bite rather than the sickle shaped claws on its feet, though these would have still been used as secondary weapons. The larger skull also has an enlarged nasal cavity, suggesting it had a great sense of smell. The ecological niche of Dromaeosaurus is a mystery, it may have preyed only on smaller dinosaurs such as the ornithopod Orodromeus, or given its powerful bite, attacked armored prey.

Dromaeosaurus is fairly well known to the public, thanks to its appearances in many television shows, including a brief role in the BBC's documentary *Walking with Dinosaurs,* as well as in many popular dinosaur books. In Mesozoica Dromaeosaurus will appeal to many fans of carnivores and an exhibit of them could shed more light on the behavior and physiology of this species.

### Dromaeosaurus' History in Mesozoica

Dromaeosaurus was announced at an unknown date on Twitch, but unexpectedly received backlash as many fans felt that there were too many carnivores in the game.
Irritator

Irritator is a medium sized carnivorous dinosaur from Early Cretaceous Brazil. Its unusual name comes from the frustration paleontologist Dave Martill felt when examining the skeleton. Unfortunately the holotype fossil had been unearthed by fossil poachers who had edited the fossil with plaster to make it look more complete and valuable looking. When Martill had removed the plaster, the dinosaur was revealed to be a spinosaurid, similar to Baryonyx. Irritator is one of the smaller members of the family, but is still a relatively large animal. Like all members of the spinosaurid family its diet would have primarily been fish, but an Irritator tooth embedded in a pterosaur backbone suggests its diet may have been more varied.

Irritator is not as well known as many other spinosaurids, but has been growing in popularity recently, thanks to its unusual name. Like all spinosaurids, fish are essential in its diet, but it may be less picky than other spinosaurids and will attack other animals.

### Irritator's History in Mesozoica

Irritator was highly requested by the fans so that the game could have the main 4 spinosaurids in the game, already having Baryonyx, Suchomimus, and Spinosaurus. On September 20, 2015, Irritator was announced for the game and was given the nickname "Shia LaBeouf" after an obsession the community had at the time.
Chasmosaurus

Chasmosaurus is a medium-sized herbivorous dinosaur from Late Cretaceous Canada. It is a member of the ceratopsian family and a relative of the more famous Triceratops, but compared to other advanced ceratopsians, it is quite small, averaging at around 4 to 5 meters in length. The most distinguishing feature of Chasmosaurus is its huge frill. Despite its large size, the skull was relatively light, due to large fenestra holes in the frill. These holes would have been covered in skin in life and may have been brightly colored or patterned for display purposes courtship. The horns, like many from the chasmosaurine family are small. It is unknown whether they were used for defence or if ceratopsians in this family relied on their large display frills to threaten foes. Much like Styracosaurus, there were once many species of Chasmosaurus found throughout eastern Canada and in Texas, but these were eventually sorted into their own genus, including Agujaceratops from Texas and Vagaceratops which lived alongside Chasmosaurus.

Chasmosaurus is a well-liked dinosaur in general. Your guests will enjoy seeing this small ceratopsian and its vivid display crest.

### Chasmosaurus' History in Mesozoica

Chasmosaurus was a fan favorite among the Ceratopsians. It was announced as a Kickstarter Backer choice on December 25, 2015 on their official Facebook page. On February 1, 2015, a second skin option was revealed and another on June 20 of this year.
Guiyu Oneiros

Guiyu is an early fish from China and lived the Silurian period. It is one of the oldest bony fish with jaws, an essential stage in evolution. Before the evolution of jaws, fish had a limited variety of diets and were mostly substrate feeders or parasites such as lampreys. With jaws, they could take on new ecological niches. It is still uncertain what Guiyu's diet was, though it may have been an omnivore. Guiyu is related to coelacanths, another family of ancient fish that evolved much later in the Devonian period. It seems that the Kuanti Formation harboured many other types of jawed fish before the Devonian explosion in fish species. Other fish included the massive Sparalepis and the large mouthed Megamastax, which may have reached a meter in length. These larger species would have been a threat to the much smaller Guiyu and other primitive fish, such as slower moving pacoderms.

Guiyu is not a large fish, but will make a great addition to aquariums, possibly in shoals.
Diabloceratops

Diabloceratops is a medium sized ceratopsian from North America during the Late Cretaceous period. It was among the earliest ceratopsians to evolve in America and lived in the Wahweap Formation, which has only recently been studied. Diabloceratops has a distinctive face, with a thin frill, two horns above the eyes and two at the top of the frill. The horns on the frill inspired the species name, but were most likely not used for combat and were instead for display and to make the dinosaur look more threatening to rivals and predators. The horns above the brow would have made a deadly weapon with a upwards stabbing motion. Diabloceratops belongs to the centrosaurinae branch of ceratopsians, which are characterised by their large nasal horns or in the case of Diabloceratops, ornate shields. The other branch, the chasmosaurinae are distinguished by larger, less ornate shields and less prominent horns. Other members of the centrosaurinae family include Centrosaurus, Styracosaurus and Pachyrhinosaurus. Diabloceratops is the oldest of the centrosaurineae and still retains some of the features of more primitive ceratopsians such as Protoceratops, such as the nasal ridge and spaces in the frill, a feature that would disappear in later centrosaurines but was retained by chasmosaurines.

The only fossil found so far of Diabloceratops is its skull. Other dinosaurs found in the Wahweap formation include primitive hadrosaurs, Acristavus and Adelolophus, the oldest tyrannosaurid, Lythronax and yet to be named pachycephalosaurids, raptors and ankylosaurids. Also present was Machairoceratops, a relative of Diabloceratops.

Diabloceratops is a recent discovery, but is quickly gaining popularity with its distinctive face and horns. This interesting herbivore and herd of Diabloceratops is guaranteed to attract many visitors.

### Diabloceratops' History in Mesozoica

Diabloceratops was announced alongside Dimorphodon on July 25, 2015 as many fans wanted more herbivores and pterosaurs in the game. Diabloceratops was also shown a lot in the Twitch streams during Kickstarter.
Placerias

Cordsaphisasaureus Offatackldile Definguoote

Placerias was a species of dicynodont from the late Triassic. It was among one of the last dicynodonts (though some may have lived on until the Early Cretaceous in Australia) and were some of the largest herbivores in the Triassic. A herding animal, Placerias used its tusks to dig for plant matter and also for defense against predators such as the giant Postosuchus. Fossil evidence also suggest that Placerias spent a lot of time in the water like a hippo.

A herd of Placerias makes for an interesting exhibit, especially when next to Triassic dinosaurs such as Plateosaurus, a combination of the old regime from the Permian and the newly developed dinosaurs that would replace them.

### Placerias' History in Mesozoica

Placerias was a Kickstarter Backer Choice and was unveiled as one with a Panda skin the Backer requested, with the modeler posting a second skin option afterwards.
Neovenator

Neovenator is a large carnivorous dinosaur from the Isle of Wight in the United Kingdom and lived in the Early Cretaceous period. Part of the first fossils of Neovenator was found in 1978, but they were very fragmentary and couldn't give any full indication of what kind of animal it was. This all changed in 1996 when an almost complete skeleton was found. Neovenator shares many similarities to carcharodontosaurid family, sharing the same long skull, three fingered arms and similarly shaped teeth, but was eventually given its own family, the Neovenatoridae, an offshoot of the allosaurids which also included the swift North African predator Deltadromeus. The type specimen of Neovenator measured 7.5 meters, or 24.6 feet, but some isolated remains suggest it could grow larger, to 10 meters or 32.8 feet. This would make it the largest carnivorous dinosaur found in Europe so far, rivalling Megalosaurus and Baryonyx, the current leaders.

Neovenator lived alongside a lush variety of dinosaurs in the wet and warm environments in the Isle of Wight in the Early Cretaceous, including the ornithopods Iguanodon, Mantellisaurus and Hypsilophodon, the armored Polacanthus and Hylaeosaurus, the large fish eating Baryonyx, the tyrannosairid Eotyrannus and several sauropods. The light ornithopods would have been its main prey and it was powerful enough to tackle the large Iguanodon.

Neovenator is still a relatively new discovery and is growing in popularity along with many of the Wessex formation, especially among visitors from the United Kingdom. It is also a large and impressive animal to attract many fans of carnivores and will be the highlight of an area of the park devoted to the European dinosaurs.

### Neovenator's history in Mesozoica

Neovenator was confirmed to be in the game by one of the Kickstarter backers on April 23, 2017.
Postosuchus

Postosuchus was an enormous rauiscuchidae from North America during the Late Triassic. Rauisuchuds were predatory archosaurs from the Triassic period. Though relatives of crocodiles, they were terrestrial and became extinct at the end of the Triassic from growing competition from the recently evolved dinosaurs, but for a brief time they were the dominant land predators through the period. The largest Rauiscuhud found so far is Saurosuchus from Argentina. Postosuchus used ambush tactics to attack large prey, but was also equally fast enough to catch smaller prey items. Postosuchus was the apex predator of the Chinle and Petrified Forest formations, until the end of the Triassic. Its prey items would have included the herbivores Placerias, Trilophosaurus, Desmatosuchus, Typothorax and perhaps the many kinds of lobe finned freshwater fish. Alongside it were small therapod dinosaurs such as Coelophysis, which may have also found themselves preyed upon by Postosuchus.

Postosuchus is an interesting animal to exhibit, giving tourists a taste of Triassic predators outside of therapod dinosaurs. Postosuchus is also a great draw for fans of predatory animals.

### Postosuchus' History in Mesozoica

Postosuchus was picked by a Kickstarter Backer and the model was shown off on March 28, 2016.
Dunkleosteus

Dunkleosteus is a large carnivorous fish from the Devonian period. It is a member of the placodermi, an ancient family of fish characterized by their bony armored fronts. Placodermi lived from the Middle Silurian to the Late Devonian and contained many species, including the tiny bottom feeder Bothriolepis, the medium Eastmanosteus and the large filter feeding Titanichthys. Dunkleosteus was the largest placoderm species, rivaled only by Titanicthys. Like many larger placoderms it suffered by being classified in the outdated wastebasket taxon Dinichthys, a genus that was treated similarly to the dinosaur Megalosaurus where several large carnivorous placoderms were assigned in this genus with little care. Like many other placoderms, Dunkleosteus had armor covering its head and half its body, while the other half was unarmored, hence why most fossils of placoderms found are the upper parts of their bodies. The lower half only came to light with the discovery of Eastmanosteu. Dunkleosteus was the apex predator of its age and its large bone covered teeth specially evolved to crush the armor and shells of other placoderms and trilobites. Because of the armor covering its head and upper body, Dunkleosteus was a slow swimming animal and would primarily prey on other slow moving animals. The only thing that could threaten a Dunkleosteus was another of its kind and bite marks on Dunkleosteus fossils show it was either territorial or a cannibal.

Dunkleosteus is a very popular animal, one of the most iconic of Paleozoic fauna, along with Dimetrodon and trilobites. A Dunkleosteus exhibit is a must have for any park focusing on life before the dinosaurs. However care must be taken when housing these fish; they are highly territorial and will prey on smaller individuals and their powerful teeth can rip through weaker exhibit walls and smash glass.

### Dunkleosteus' History in Mesozoica

Dunkleosteus was first announced on August 24, 2015. Although fans loved having the fish added to the game, many disliked the skin, causing the developers to create another one that was released later that same day, which was better received, although both skins will be in the game.

Tylosaurus

Tylosaurus is a huge marine reptile from Late Cretaceous North America. It is a mosasaur, a family of powerful marine carnivores that emerged in the Late Cretaceous, after the icthyosaurus went into decline at the Middle to early Late Cretaceous, for as of yet unknown reasons, with the mosasaurs taking their vacant niche. The mosasaurs' closest living relatives are monitor lizards and snakes, sharing very similar anatomy features such as a second set of teeth growing from their palate to grip food. The mosasaurs adapted into many ecological niches, Tylosaurus was most certainly a fast apex predator with its enormous jaws and strong tail, hunting large fish, sharks and other marine reptiles such as Elasmosaurus and smaller mosasaurs.

Mosasaurs have grown in popularity over the centuries they have been known to science, with the first mosasaur fossils (of Mosasaurus itself) being found in the Netherlands in 1764, nearly 80 years before the term 'dinosaur' was coined. Tylosaurus being one of the largest is sure to draw many visitors.

### Tylosaurus' History in Mesozoica

Tylosaurus was with the game from the beginning, being what was used to show that aquatic animals will be added to the game eventually and since then many more have been added.
Diplodocus

Diplodocus is a large Late Jurassic sauropod from the famous Morrison Formation in the USA. Diplodocus was at one point the largest dinosaur in the world in terms of length, with a graceful long neck and tail at near equal lengths. Diplodocus, like many sauropods, did not chew its food. The teeth were peg like and used to sheer leaves from ferns which were then swallowed whole and ground up in the stomach by gastroliths, stones the dinosaur had swallowed. Diplodocus may have had a series of spines down its back, but this has not yet been fully confirmed yet. The main methods of defense for a Diplodocus were its sheer size, that would have deterred many predators such as Ceratosaurus and a whiplash tail. Its main enemies would have been the large carnivores Allosaurus and Torvosaurus.

Diplodocus has been a long standing favorite among the general public for over a century. Diplodocus became popular thanks to several casts of a complete skeleton (known as Dippy) sent to museums all over the world by Andrew Carnegie, a Scottish-American steel industry tycoon, as well as numerous appearances in literature, film and video games. Diplodocus will be a welcomed and celebrated exhibit in any park.

### Diplodocus' History in Mesozoica

Diplodocus was made famous in its appearance in the BBC special Walking with Dinosaurs and was originally supposed to appear in Jurassic Park: Operation Genesis but was cut. Since then, fans have wanted the dinosaur to appear. On June 25, 2015, Diplodocus was officially announced as part of the game.
Kentrosaurus

Kentrosaurus is a medium sized herbivorous dinosaur from Late Jurassic Tanzania. It is known from a complete skeleton and hundreds of incomplete specimens found together in a single bonebed, showing that these animals herded. Kentrosaurus is a member of the stegosaurid family and is the Tendaguru equivalent of Stegosaurus in its ecosystem, though Kentrosaurus seems to have been more closely related to Chinese stegosaurs like Tuojiangosaurus than to Stegosaurus. Unlike its North American relative, Kentrosaurus had smaller, narrower plates that ran in equal pairs from its neck to halfway up its back. The lower half of its back and its tail instead had pairs of spikes for defensive purposes. An additional pair of spikes at its shoulders, providing protection for its head. Kentrosaurus was a low browser, feeding on club moss shrubs and ferns. It shared its home with sauropods such as Dicraeosaurus and the small ornithopod Dysalotosaurus (which is potentially an African species of Dryosaurus).

Kentrosaurus has steadily grown in popularity throughout the years since its discovery, usually portrayed as an ally or friend of Stegosaurus in many media, when it was unlikely these species would have ever met. Your visitors will find the smaller Kentrosaurus to be very cute and yet also impressive with its array of spikes.

### Kentrosaurus' History in Mesozoica

Kentrosaurus appeared in Jurassic Park: Operation Genesis, making it a must have for many fans. It was announced on October 9, 2015 as one of the last models before the Kickstarter Backer Choices began to be made.
Ouranosaurus

Ouranosaurus is an interesting medium sized ornithopod from the Cretaceous period of Niger, known from two complete skeletons and the remains of several others. The most distinctive feature of this species is the tall neural spines found in the fossil specimens. Originally thought to support a colorful sail much like Spinosaurus or Dimetrodon, the spines however resemble more those of humped animals like bison or camels, therefore Ouranosaurus may have had a fatty hump rather than a sail, but this is still debated. Ouranosaurus lived alongside the sauropod Nigersaurus, fellow iguanodontians Lurdusaurus and Elrhazosaurus, the carnivorous dinosaurus Suchomimus, Kryptops and Eocarcharia and the gigantic crocodile Sarcosuchus. Ouranosaurus was no doubt on the menu for many of the predators and would have relied on herding and speed to avoid them.

Ouranosaurus is a relatively obscure animal to the general public, but its unusual appearance will no doubt attract the attention of many guests to Mesozoica.

### Ouranosaurus' History in Mesozoica

Ouranosaurus was part of the dinosaurs in the original Jurassic Park: Operation Genesis, making it a must have for many fans. A Kickstarter Backer added Ouranosaurus to the game.
Protoceratops

Protoceratops is a small herbivore from Late Cretaceous Central Asia. A relative of the multitude of larger Ceratopsians from North America such as Triceratops and Styracosaurus, Protoceratops was a widespread animal in its range, with numerous fossils and nesting sites found across the Gobi desert. Unlike its larger cousins, Protoceratops has no horns, but it does posses a small frill and a bump on its nose, which could have been used for ramming predators and as a display. Along the tail are a series of quill like feathers, the purpose of which is unclear. Protoceratops also posses a beak for shredding plant matter and also possibly for defense. The main predators of Protoceratops would have been the swift Velociraptor and the huge Tyrannosaurid Tarbosaurus. It lived in huge herds for protection and an early warning.

Protoceratops' small size and colorful frill will no doubt endear it to many visitors. Its high birth rate will also delight many with adorable Protoceratops babies and interesting nesting behavior from the adults.

### Protoceratop's History in

Protoceratops was a fan favorite dinosaur and was eventually added to the game on November 9, 2016.
Elasmotherium

Elasmotherium was an enormous species of rhino from the Pliocene and Pleistocene periods. It was found throughout Asia and into Eastern Europe. The main feature of Elasmotherium, aside from its size, is its large horn. Although sizes are estimated, since no intact horn cone has been found, the sheer size of the animal would suggest a large horn. It is often confused with Coelodonta, the famous woolly rhino, a much later species which is smaller and has a more curved horn. While Coelodonta was covered in thick woolly fur Elasmotherium may not have been furred, though the debate still continues to this day. Unlike Coelodonta, Elasmotherium most likely never met early humans, although recent fossils in Kazakhstan suggests that Elasmotherium populations survived in some areas long enough for humans to encounter them. The huge horn of Elasmotherium may have been the inspiration for unicorns after ancient people found cave paintings or some other artistic depiction left by early humans and assumed it was some sort of mythological creature. However this has not been fully proved and other theories on the unicorn's origin may be more plausible, or a combination of multiple origins.

Elasmotherium is an instant eye catcher in any prehistoric mammal collection, thanks to its enormous horn. Your guests will find Elasmotherium a wonderful, almost legendary creature.

Elasmotherium was added as a Kickstarter Backer choice on December 23, 2015.
Temnodontosaurus

Temnodontosaurus is a large ichthyosaur from Europe during the Early Jurassic period. It is one of the largest in the family and was a pelagic hunter; patrolling the open seas. Studies of wear and tear on its teeth and stomach contents show that Temnodontosaurus ate hard-shelled animals such as ammonites and belemnites, as well as squid and fish. Given its size and strength, it may also have eaten smaller ichthyosaurs and other marine reptiles, but this has yet to be confirmed. Like most other Jurassic ichthyosaurs, Temnodontosaurus has a streamlined fish like body with four paddle like fins and a strong tail, designed for speeding through the water and like other ichthyosaurs, it gave birth to live young in the sea, since their fish like bodies would make it difficult or impossible to crawl onto land to lay eggs. Temnodontosaurus had large eyes, suggesting it dwelt in deep waters and its large body meant it could carry more oxygen and stay in the depths for longer. However their large size meant that it relied heavily on shelled creatures to sustain itself. Perhaps ammonite populations fell in the latter half of the Early Jurassic, which brought about the end of Temnodontosaurus.

A shoal Temnodontosaurus is a spectacular animal for a marine exhibit for many visitors, thanks to their huge size and graceful swimming. Temnodontosaurus will need plenty of food to sustain its large body and it is unadvised to house it with smaller ichthyosaurs; while it may not attack them, its size may cause worry among the smaller animals.

### Temnodontosaurus' History in Mesozoica

Temnodontosaurus was added to the game on June 30, 2015, adding to the sea life already in the game. This animal was likely chosen due to it being one of the largest Ichthyosaurs ever known.
Inostrancevia

Inostrancevia is a large carnivorous synapsid from Russia during the Permian period. It is the largest member of the gorgonopsid family, a successful family of the middle and late Permian. Inostrancevia was the top predator of its time and shared its home with the massive armored herbivore Scutosaurus. A full grown Scutosaurus in its prime was probably not on Inostrancevia's menu, being too large and powerful, but it would have targeted weak, injured and young members of Scutosaurus herds; its large canine teeth and strong jaws making short work of its prey.

Inostrancevia is an impressive animal for Permian displays. Although its not as famous as its smaller cousin, Gorogonops from South Africa, it will still be a great draw for many visitors. Being smaller than many carnivorous dinosaurs, it is easier to keep, however its still a powerful animal and an active hunter that should not be taken lightly.

### Inostrancevia's History in Mesozoica

Inostrancevia was a Kickstarter Backer Choice and was shown to the public on February 10, 2016.
Apatosaurus

Apatosaurus is a large sauropod from Late Jurassic USA and is one of many sauropods found in the Morrison Formation. Apatosaurus is similar to another Morrison Formation sauropod, Diplodocus, but differs in being shorter and more robust, with heavier, more solid bones. Because of this, Apatosaurus is considered more primitive than most other Morrison Formation sauropods. Like Diplodocus, Apatosaurus also had a whiplash tail used for defense and visual communication.

The most fascinating aspect of Apatosaurus doesn't actually have to do with its biology or ecology, but with its naming and its relationship with the name Brontosaurus. In 1877 paleontologist Othniel Charles Marsh discovered and named the sauropod *Apatosaurus Ajax*. Two years later in 1879, he found another sauropod skeleton, which was better preserved than his Apatosaurus specimen and named it *Brontosaurus Excelsus*. Much later in 1903 a study into the two sauropods found that they were in fact the same species and because Apatosaurus was named first, by naming procedure, *Brontosaurus Excelsus* would need to be renamed *Apatosaurus Excelsus.* However confusion spread among the general public after a museum mounted an Apatosaurus skeleton in 1905, but it was made from fossils of other dinosaurs, most notably a skull from Camarasaurus and labelled 'Brontosaurus'. The owner of the museum, Henry Fairfield Osborn, an opponent of Marsh labelled his display Brontosaurus in retaliation against Marsh. News of the display spread across the world and Brontosaurus became a cultural icon throughout much of the 20th century, appearing in many books and films, including the 1914 cartoon *Gertie the Dinosaur* 1925 silent movie *The Lost World.* Apatosaurus faded into obscurity during this period, until later on in the 1970 and onward, with the discovery of a complete skull of Apatosaurus and the removal of the Camarasaurus skull from the 'Brontosaurus' specimen. Despite the recent discovery being well publicized, Brontosaurus was continually used in many fictional media. In 2015 a study was conducted with the two original Apatosaurus species again and claimed it had found enough differences to reinstated *Brontosaurus Excelsus,* but this is still heavily debated. The Apatosaurus/Brontosaurus debate is one of the most famous and strangest in the field of paleontology.

Despite the confusion of naming, Apatosaurus has remained a very popular dinosaur, thanks to its appearances in many media after 1970, including *Jurassic World* and most notably in the Don Bluth animated movie *The Land Before Time,* with the main character, Littlefoot, being an Apatosaurus. This sauropod will delight many visitors.

### Apatosaurus' History in Mesozoica

Apatosaurus was added to the game by a Kickstarter Backer who wanted it in the game to have more dinosaurs from the *Jurassic Park* films and books. The skin is inspired by Little Foot from *The Land Before Time* series.
Edmontosaurus annectens

Edmontosaurus annectens is a large herbivorous dinosaur from Late Cretaceous North America. A member of the hadrosaur family, it has many typical hadrosaur features including a wide toothless beak, batteries of tightly packed molars at the back of its jaws, shorter forearms and powerful back legs which could allow the animal to rise in a bipedal mode. Edmontosaurus annectens is very similar to fellow Late Cretaceous hadrosaur Edmontosaurus but has a differently shaped beak. The debate still continues whether this should be classed as a subspecies of Edmontosaurus or a completely different genus, Anatosaurus. Edmontosaurus annectens is known from several fossils, including a mummified specimen with internal organs and skin impressions, giving a detailed picture of this animal.

### Edmontosaurus annectens' History in Mesozoica

Anatosaurus was originally going to appear as Edmontosaurus but as time went on, the desire to include both species pushed for the inclusion of Anatosaurus to appear in the game. However, as of now the dinosaur is currently labeled as Edmontosaurus annectens.

### In-game description

"The Edmontosaurus ("Edmonton lizard") was a North American hadrosaurid dinosaur from the late cretaceous. This animal was one of the largest of its kind' some fossils suggest a length of 15 meters. Edmontosaurus, like other hadrosaurs, was capable of moving on its hind limbs in a bipedal stance."
Hylaeosaurus

### Dig Site(s)

Uncertain; possibly The Wessex Formation, Tunbridge Wells Sand Formation or Fossil Market exclusive.

## Hylaeosaurus

Hylaeosaurus is an armored Nodosaur from Early Cretaceous Britain. It was among the first dinosaurs to be named along with Megalosaurus and Iguanodon. It is a relatively unknown dinosaur, only fragments have been found of it from the county of West Sussex in southern England, but it appears to be a basal member of the nodosaurid family or an ancestor to the ankylosaurids.

Other remains have been found in France, Germany, Spain and Romania, but these may be their own separate genus. The study of Hylaeosaurus is complicated by lack of fossil material and an abundance of armoured dinosaurs living in England during the Cretaceous; including Polacanthus from Isle of Wright's Wessex Formation, Anoplosaurus and Acanthopholis from Cambridgeshire but from a later time in the Cretaceous and Horshamosaurus also from West Sussex. This has also plagued other British dinosaurs, such as Macrurosaurus, a sauropod that had remains attributed to it which later turned out to belong to Acanthopholis. Future evidence may whittle down the currently abundant species of armoured dinosaurs in this time and place, or may even validate their species.

Unlike Megalosaurus and Iguanodon, Hylaeosaurus is not very well known to both science or the general public. Perhaps exhibiting a few in your park could shed some light on this mysterious dinosaur and introduce an old species to visitors.

### Hylaeosaurus' History in Mesozoica

Hylaeosaurus was announced to be part of the game with Iguanodon and Megalosaurus on July 5, 2015 due to the dinosaurs being the first three to create the genius.

Hypsilophodon

## Hypsilophodon foxii

Hypsilophodon is a small herbivore from Early Cretaceous Britain. A bipedal dinosaur, it had a small beak filled with sharp teeth for shredding plant material and four fingered hands. Among the earliest dinosaurs to be discovered, Hypsilophodon was at first thought to have been a juvenile Iguanodon, more discoveries showed that it was in fact a completely different species. For most of the 1800s, it was erroneously believed to have lived in trees like a tree kangaroo until in 1894 when it was depicted correctly as a ground dwelling dinosaur. It is the most abundant dinosaur in the Wessex Formation in the Isle of Wight and would have been the main prey item for small to medium carnivorous dinosaurs such as Eotyrannus. Its main means of defense would be herding and fleeing carnivores and may also have mixed with herds of larger dinosaurs such as Iguanodon. Due to its small size, Hypsilophodon fed on low growing plants, such as young shoots and roots. From Hypsilophodon skulls, it can be deduced that ornithischian teeth were continuously replaced as they were worn down. Hypsilophodon also had cheeks, an advanced feature which helped in food being chewed.

Hypsilophodon's docile nature means it is well suited to captivity and mixes well with other herbivores. It will appeal to many visitors for its cute appearance and gentle demeanor.

### Hypsilophodon's History in Mesozoica

Hypsilophodon was added by a Kickstarter Backer to the game due to its appearance in the *Jurassic Park* book. The model was unveiled on June 8, 2016.
