Allosaurus (/ˌæləˈsɔːrəs/) is a genus of large carnivorous theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic epoch (Kimmeridgian to late Tithonian. The name "Allosaurus" means "different lizard" alluding to its unique (at the time of its discovery) concave vertebrae. It is derived from the Greek ἄλλος (allos) ("different, other") and σαῦρος (sauros) ("lizard / generic reptile"). The first fossil remains that could definitively be ascribed to this genus were described in 1877 by paleontologist Othniel Charles Marsh. As one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles. Allosaurus was a large bipedal predator. Its skull was light, robust and equipped with dozens of sharp, serrated teeth. It averaged 10 meters (33 ft) in length, though fragmentary remains suggest it could have reached over 12 m (39 ft). Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced by a long and heavily muscled tail. It is classified as an allosaurid, a type of carnosaurian theropod dinosaur. The genus has a complicated taxonomy, and includes three valid species, the best known of which is A. fragilis. The bulk of Allosaurus remains have come from North America's Morrison Formation, with material also known from Portugal. It was known for over half of the 20th century as Antrodemus, but a study of the copious remains from the Cleveland-Lloyd Dinosaur Quarry brought the name "Allosaurus" back to prominence and established it as one of the best-known dinosaurs. As the most abundant large predator in the Morrison Formation, Allosaurus was at the top of the food chain, probably preying on contemporaneous large herbivorous dinosaurs, and perhaps other predators. Potential prey included ornithopods, stegosaurids, and sauropods. Some paleontologists interpret Allosaurus as having had cooperative social behavior, and hunting in packs, while others believe individuals may have been aggressive toward each other, and that congregations of this genus are the result of lone individuals feeding on the same carcasses.

for The Fauna in Monstrosities Commando : Mission Skull Island
Suggested by nikobatman
After years of disappearance, Dracula's son has finally been found by human authorities. The all-powerful Alucard has been captured in Los Angeles after eliminating a dangerous warlock, one of those who summoned Deak to Earth a few months ago, nearly triggering an Apocalypse. However, Alucard, although taken to "The Fair," the top-secret international super-prison in Alaska for the worst monsters and other monstrous beings, isn't destined to remain there. Director Kennedy of Prodigium has another idea : to lead a commando of "monstrosities" on a top-secret mission to a mysterious place called Skull Island. There, they've taken refuge in what appears to be the last stronghold of the Cobra Cult, now led by Baron Schweiger, who has enhanced himself with the blood of the deceased Queen Lamian. Their mission is to neutralize the Cult once and for all ! But once on this island, they'll realize that the Cult isn't necessarily the most dangerous thing : a far more powerful being is the King !
