But Stegosaurus' most interesting feature is the double rows of large, bony plates running down it's spine. It's body design is unique: it has a bulky, quadrupedal design, medium-length tail, and small head. Stegosaurus is an interesting animal, to say the least. It is thought that, with this wide gape, it would have ran towards its prey, and then clamped down on the body of the prey animal and would cut through the flesh like a saw blade with its serrated teeth, with the goal of weakening and making the prey bleed out.Stegosaurus was originally named and found by Othniel Charles Marsh in 1877, from remains recovered north of Morrison, Colorado two species are know from the remains Stegosaurus armatus and Stegosaurus stenops.
Due to the increase of neck muscles but decrease of jaw muscles, Allosaurus possessed a wide gape. It is commonly thought that Allosaurus' s jaws were analogous to that of a hatchet. jimmadseni is geologically the oldest species of Allosaurus.Īllosaurus was found in 1877 by Othniel Charles Marsh and its name means "different lizard". Being discovered from the Lower Morrison Formation, A.
jimmadseni had thin, blade-like crests that ran over its snout and reached its highest point over the eyes. who was the first state paleontologist in Utah. jimmadseni, that was named after James H. However, there is still a third species of Allosaurus which was described in 2020, called A. maximus, it is now thought that Saurophaganax was its own distinct genus based on the new view of basal tetanuran theropods, and some new Saurophaganax material from New Mexico may help clear up the status of this genus. Although in-game Allosaurus contains the species A. It is speculated that Allosaurus was a pack hunter due to the large accumulation of Allosaurus remains at the same sites. There is evidence for cannibalism amongst Allosaurs, such as shed teeth amongst rig fragments, possible tooth marks on a shoulder blade, and cannibalized skeletons among the bones at various lair sites. europaeus was contemporaneous with Miragaia, Lusotitan, Dinheirosaurus, Lourinhanosaurus, and the European Torvosaurus species T. fragilis lived alongside other famous dinosaur species from the Morrison Formation, such as Dryosaurus, Stegosaurus, Ceratosaurus, Torvosaurus, Camarasaurus, Diplodocus and Brachiosaurus. tendagurensis, was thought to have come from the Tendaguru Formation in Tanzania, Africa, however the remains were eventually considered to be indeterminate and possible the remains of an unnamed megalosauroid or carcharodontosaurid.Ī.
europaeus also developed far more boxy crests compared to the pointed and rugged ridges of A. europaeus was still an intimidating animal. europaeus is the smallest and was found in Portugal rather than North America. The closely related Saurophaganax was also present in the Morrison Formation and lived at the same time and place as Allosaurus, meaning it would have faced fierce competition for resources as these both are closely related and in turn have similar builds, though Saurophaganax was much larger than Allosaurus.Ĭompared to the others, A. fragilis being the default due to its established presence in popular culture as well as the fact that it is the type species of the genus Allosaurus. In-game, all three skins correspond to a different species of Allosaurus with A. It is also recognized for its distinct pair of horns above the eyes, an extension of the lacrimal bone which are in the front of the eyes, a trait which varies among the various species of Allosaurus.
