***Albertosaurus*** is a genus of tyrannosaurid dinosaur in the *Jurassic World Evolution* series. Originating in Late Cretaceous North America, *Albertosaurus* is physically similar to *Tyrannosaurus*, though is smaller, faster, and more slender in comparison.

In *Evolution*, *Albertosaurus* is available in the *Claire's Sanctuary* DLC, where it is introduced in the campaign as one of the carnivorous species facing extinction on Nublar North, and can subsequently be relocated to Sanctuary. Upon completion of the *Claire's Sanctuary* story missions, *Albertosaurus* becomes available in the main campaign by progressing through the Entertainment Division on Isla Pena, where its fossils can subsequently be excavated in the Dinosaur Park and Horseshoe Canyon formations in North America.

## Characteristics

Very similar in appearance to its infamous relative *Tyrannosaurus*, albeit comparatively smaller and thinner, *Albertosaurus* is a relatively large carnivorous tyrannosaurid theropod from the Late Cretaceous Period, found in North America. Like other tyrannosaurids, *Albertosaurus* has small arms, muscular legs, short bony crests above its eyes, a huge head with numerous large teeth, and a number of adaptations that allows its skull to withstand the forces it exerts on its prey. Believed to have been the apex predator of its time, *Albertosaurus'* rows of razor-sharp teeth make light work of the smaller, herbivorous dinosaurs it preys on while its sheer size – approximately 9.5 meters long and weighing around 4 tons – ensure other predators steer clear. Tyrannosaurids typically bit deeply into a carcass, then pulled back, and their serrated teeth were an indispensable tool in this motion. Tooth serrations lead, via what resembles a crack, to a round void known as an ampulla. These voids spread forces to a larger surface area on the tooth, lessening the risk of a crack developing. In addition to serrated teeth, *Albertosaurus* has a strong skull with a fused nasal bone and feet that can resist twisting motions as it tore at its prey. Based on the fossil evidence, *Albertosaurus* had a high mortality rate until it reached an age of around 2 years old, at which point it was the largest carnivore in its environment and no longer at risk of predation. At its peak, *Albertosaurus* grew by 112kg per year. *Albertosaurus*, like other tyrannosaurids, was highly sensitive to smell and sound due to its large olfactory lobes and ear canals.

Prior to the eruption of Mount Sibo, at least one *Albertosaurus* was brought to Claire Dearing's facility on Isla Nublar, along with *Baryonyx* and *Carnotaurus*, in order to research the disease threatening the island's dinosaurs with extinction. After the abandonment of Nublar, the *Albertosaurus* genome was available to the facility on Sanctuary. In *Evolution*, the base genome of *Albertosaurus* is a light gray body with a blue stripe-like pattern all around and a lighter gray underside.

## Gameplay

#### Behaviour

*Albertosaurus* is a unique addition to the Jurassic World parks, and can often be seen sniffing the air, ground, and water of its environment. Like other carnivores, it can eat from both the Live Bait and Carnivore Feeders, though it can also hunt a wide variety of dinosaur species, except for sauropods. While content with solitude, *Albertosaurus* can tolerate another member of its kind in the same enclosure, as well as up to eighteen other dinosaurs of varying species.

## Paleontology

*Albertosaurus'* name is derived from the location of its earliest discoveries – Alberta's Horseshoe Canyon Formation. The first known *Albertosaurus* fossil consisted of a partial skull discovered and excavated by geologist Joseph B. Tyrrell in June 1884 in the Red Deer River, Alberta, by the Geological Survey of Canada. Five years later, a second skull was discovered by Tyrrell's colleague Thomas Chesmer Weston in 1889. The team, not equipped with the proper tools to manage such a find, damaged the skull during its recovery. In 1892, the two skulls were originally assigned incorrectly to the existing Laelaps incrassatus species now known as *Dryptosaurus*.

The specimens were determined to differ too greatly from *Dryptosaurus* and were finally given a new name, *Albertosaurus*, in 1905 by American paleontologist Henry Fairfield Osborn. In August 1910, a large group of *Albertosaurus* was partially excavated at another nearby quarry by American paleontologist Barnum Brown. Paleontologist Phil Currie resumed excavations in 1997 after he relocated the bone bed from photographic evidence. The number of individuals can be calculated from the number of unique skeletal elements found - if this estimate is used, the bone bed contained 12 unique *Albertosaurus* specimens. If instead we count skeletal elements that occur multiple times in one animal, but differ in size, there could be as many as 26. The large number of unique individuals found could be evidence of pack behavior, or the animals may have been brought together by a drought or flood.

Due to abundant remains, especially from the Dry Island bone beds, *Albertosaurus* is one of the best-studied and understood tyrannosaurs. Its extensive range across multiple formations suggests that this was a common predator and the remains of juveniles and adults together indicate that they traveled together in family groups. Juveniles grew rapidly and may have reached adulthood at about 18 years, similar to humans. Typical *Albertosaurus* adults measured up to 9 m (30 ft) long and weighed 1.3-2.5 tons, while rare individuals of great age could grow to be over 10 m (33 ft) long and weighed 4 metric tons.

When compared to its later cousin, *Tyrannosaurus*, *Albertosaurus* is lightly built and more streamlined. This suggests it mainly chased down fast prey such as hadrosaurs, rather than tackling tougher prey such as ceratopsians or ambushing its prey. Some paleontologists have speculated that *Albertosaurus* could run as fast as 30 mph (48 km/h).

The skull was large and possessed fewer teeth than other theropods. Though its jaws weren't as powerful as its larger relative, *Tyrannosaurus*, it was capable of biting with a force of over 3000 newtons and had similar characteristics such as fused nasal bones and maxillary bones adapted to resist lateral forces, allowing it to employ a "puncture and pull" method to tear apart its prey. Skin impressions showed that *Albertosaurus* was covered in scales, with large pebbly hexagonal scales on its back and smaller, diamond-shaped scales on its underside.

The remains of *Albertosaurus* are so extensive that the effects of certain diseases and parasites have been recorded on some individuals. The *Albertosaurus* featured in the game is heavier and slightly larger than the average size of its real-life counterpart. In reality, the dinosaur's lacrimal brow horns are more prominent and known from *Albertosaurus* close relative, *Gorgosaurus*.

### Paleoecology

Living approximately from 71 to 68 million years ago, *Albertosaurus* was the apex predator of its ecosystem, preying on a wide variety of dinosaurs; mainly hadrosaurs, ceratopsians, and ornithomimids. Living in habitats that were semi-tropical and rich in plant life along the floodplains of Horseshoe Canyon, *Albertosaurus* lived alongside a wide array of other dinosaurs such as *Pachyrhinosaurus*, *Saurolophus*, *Edmontosaurus*, *Struthiomimus*, *Troodon*, and *Atrociraptor*.
