Dimetrodon

Dimetrodon was a species of carnivorous reptile that lived during the beginning of the dinosaur ages and quickly rediscovered in the mesozoic island. It is an Epic rarity creature and has very good survival strategies. Dimetrodons are quick on their feet and have a very powerful bite force for a lizard not a member of dinosaur families. They have a very large sail which has many usages such as contracting heat and cool air so it can regulate its body heat in order to hunt in any condition. they are somewhat purplish on this planet and upon reaching level 40 are dubbed "Unicorn Wizards" Due to their insanely weird colors and large horn that can expel magical attacks. as an Attacker class creature(Subclass: Grappler), Dimetrodon reached lengths of 3.5 meters long. during wars they go for the human ankles to bring their prey down and then use their magical horn to slice their torso in 2 with a magical crescent.

## Biology

*Dimetrodon* was a quadrupedal, sail-backed synapsid. Most *Dimetrodon* species ranged in length from 1.7 to 4.6 m (6 to 15 ft) and are estimated to have weighed between 28 and 250 kg (60 and 550 lb). The largest known species of *Dimetrodon* is *D. angelensis*, around 4 m (13 ft) and the smallest is *D. teutonis* at 60 cm (24 in). The larger species of *Dimetrodon* were among the largest predators of the Early Permian, although the closely related *Tappenosaurus*, known from skeletal fragments in slightly younger rocks, may have been even larger at an estimated 5.5 metres (18 ft) in total body length. Although some *Dimetrodon* species could grow very large, many juvenile specimens are known.

A single large opening on either side of the back of the skull links *Dimetrodon* with mammals and distinguishes it from most of the earliest sauropsids, which either lack openings or have two openings. Features such as ridges on the inside of the nasal cavity and a ridge at the back of the lower jaw are thought to be part of an evolutionary progression from early four-limbed land-dwelling vertebrates to mammals.

The skull of *Dimetrodon* is tall and compressed laterally, or side-to-side. The eye sockets are positioned high and far back in the skull. Behind each eye socket is a single hole called an infratemporal fenestra. An additional hole in the skull, the supratemporal fenestra, can be seen when viewed from above. The back of the skull (the occiput) is oriented at a slight upward angle, a feature that it shares with all other early synapsids. The upper margin of the skull slopes downward in a convex arc to the tip of the snout. The tip of the upper jaw, formed by the premaxilla bone, is raised above the part of the jaw formed by the maxilla bone to form a maxillary "step." Within this step is a diastema, or gap in the tooth row. Its skull was more heavily built than a dinosaur's

The size of the teeth varies greatly along the length of the jaws, lending *Dimetrodon* its name, which means "two measures of tooth" in reference to sets of small and large teeth. One or two pairs of caniniforms (large pointed canine-like teeth) extend from the maxilla. Large incisor teeth are also present at the tips of the upper and lower jaws, rooted in the premaxillae and dentary bones. Small teeth are present around the maxillary "step" and behind the caniniforms, becoming smaller further back in the jaw.

Many teeth are widest at their midsections and narrow closer to the jaws, giving them the appearance of a teardrop. Teardrop-shaped teeth are unique to *Dimetrodon* and other closely related sphenacodontids, and help distinguish them from other early synapsids. As in many other early synapsids, the teeth of most *Dimetrodon* species are serrated at their edges. The serrations of *Dimetrodon* teeth were so fine that they resembled tiny cracks. The dinosaur *Albertosaurus* had similarly crack-like serrations, but, at the base of each serration was a round void, which would have functioned to distribute force over a larger surface area and prevent the stresses of feeding from causing the crack to spread through the tooth. Unlike *Albertosaurus*, *Dimetrodon* teeth lacked adaptations that would stop cracks from forming at their serrations. The teeth of *D. teutonis* lack serrations, but still have sharp edges.

A 2014 study shows that *Dimetrodon* was in an arms race against its prey. The smaller species, *D. milleri*, had no serrations, since it ate small prey. As prey grew larger, several *Dimetrodon* species started developing serrations on their teeth and increasing in size. For instance, *D. limbatus* had enamel serrations that helped it cut through flesh (which were similar to the serrations that can be found on *Secodontosaurus*). The second-largest species, *D. grandis*, has denticle serrations similar to those of sharks and theropod dinosaurs, making its teeth even more specialized for slicing through flesh. As *Dimetrodon'*s prey grew larger, the various species responded by evolving into larger sizes and developing ever-sharper teeth.

On the inner surface of the nasal section of skull are ridges called nasoturbinals, which may have supported cartilage that increased the area of the olfactory epithelium, the layer of tissue that detects odors. These ridges are much smaller than those of later synapsids from the Late Permian and Triassic, whose large nasoturbinals are taken as evidence for warm-bloodedness because they may have supported mucous membranes that warmed and moistened incoming air. Thus, the nasal cavity of *Dimetrodon* is transitional between those of early land vertebrates and mammals.

Another transitional feature of *Dimetrodon* is a ridge in the back of the jaw called the reflected lamina, which is found on the articular bone, which connects to the quadrate bone of the skull to form the jaw joint. In later mammal ancestors, the articular and quadrate separated from the jaw joint, while the articular developed into the malleus bone of the middle ear. The reflected lamina became part of a ring called the tympanic annulus that supports the ear drum in all living mammals.

The tail of *Dimetrodon* makes up a large portion of its total body length and includes around 50 caudal vertebrae. Tails were missing or incomplete in the first described skeletons of *Dimetrodon*; the only caudal vertebrae known were the 11 closest to the hip. Since these first few caudal vertebrae narrow rapidly as they progress farther from the hip, many paleontologists in the late 19th and early 20th centuries thought that *Dimetrodon* had a very short tail. A largely complete tail of *Dimetrodon* was not described until 1927.

The sail of *Dimetrodon* is formed by elongated neural spines projecting from the vertebrae. Each spine varies in cross-sectional shape from its base to its tip in what is known as "dimetrodont" differentiation. Near the vertebra body, the spine cross section is laterally compressed into a rectangular shape, and closer to the tip, it takes on a figure-eight shape as a groove runs along either side of the spine. The figure-eight shape is thought to reinforce the spine, preventing bending and fractures. A cross section of the spine of one specimen of *Dimetrodon giganhomogenes* is rectangular in shape but preserves figure-eight shaped rings close to its center, indicating that the shape of spines may change as individuals age. The microscopic anatomy of each spine varies from base to tip, indicating where it was embedded in the muscles of the back and where it was exposed as part of a sail. The lower or proximal portion of the spine has a rough surface that would have served as an anchoring point for the epaxial muscles of the back, and also has a network of connective tissues called Sharpey's fibers that indicate it was embedded within the body. Higher up on the distal (outer) portion of the spine, the bone surface is smoother. The periosteum, a layer of tissue surrounding the bone, is covered in small grooves that presumably supported the blood vessels that vascularized the sail.

The large groove that runs the length of the spine was once thought to be a channel for blood vessels, but since the bone does not contain vascular canals, the sail is not thought to have been as highly vascularized as once thought. Some specimens of *Dimetrodon* preserve deformed areas of the neural spines that appear to be healed-over fractures. The cortical bone that grew over these breaks is highly vascularized, suggesting that soft tissue must have been present on the sail to supply the site with blood vessels. Layered lamellar bone makes up most of the neural spine's cross-sectional area, and contains lines of arrested growth that can be used to determine the age of each individual at death. In many specimens of *D. gigashomogenes* the distal portions of spines bend sharply, indicating that the sail would have had an irregular profile in life. Their crookedness suggests that soft tissue may not have extended all the way to the tips of the spines, meaning that the sail's webbing may not have been as extensive as it is commonly imagined.

No fossil evidence of *Dimetrodon'*s skin has yet been found. Impressions of the skin of a related animal, *Estemmenosuchus*, indicate that it would have been smooth and well-provided with glands, but this form of skin may not have applied to *Dimetrodon*, as its lineage is fairly distant. *Dimetrodon* also may have had large scutes on the underside of its tail and belly, as other synapsids did. Evidence from the varanopid *Ascendonanus* suggests that some early synapsids may have had squamate-like scales. However, some recent studies have put varanopids as taxonomically closer to diapsid reptiles.

## Discovery

Discovered in 4011, Dimetrodon packs began attacking the center of a city after coming out of the sewers. they grabbed people by the ankles and would pull them down the drain. this behavior was discovered to be a new part of hunting for them indicating they can also learn.

## Trivia

Dimetrodon horns are more valuable than rhino horns.
