Allosaurus 

Allosaurus (æləˈsɔ rəs) is a genus of carnivorous theropod dinosaur that lived 155 to 150 million years ago during the late Jurassic period (Kimmeridgian to early Tithonian). The name "Allosaurus" means "different lizard" alluding to its unique concave vertebrae (at the time of its discovery). 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. Indeed, it has been a top feature in several films and documentaries about prehistoric life.

As the most abundant large predatory dinosaur in the Morrison Formation, Allosaurus was at the top of the food chain, probably preying on contemporaneous large herbivorous dinosaurs, and perhaps even 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. Due to having a much weaker bite force and a much wider gape than most other large carnivorous dinosaurs, it may have attacked large prey by ambush, using its upper jaw like a hatchet.

sassosaurus rex 

an overtly sassy dinosaur with thunderthighs. Known to create drama amongst the other happy little herbavours. Unlike most dinosaurs of its era, the sassosaurus feeds off the angst and misery of its prey, as it shoots dagger glares and bitchy remarks at the weakest unsuspecting of the already emotionally unstable teenage dino population. Well known by paleontologists as the bitchiest of all dinosaurs. Modern female is said to have evolved from the sassosaurus.

look at those thunderthighs! she must be a sassosaurus rex!

A Jurassic dinosaur represented by 4-6 identified species. Ranging in length from 5-13.5 meters, it was one of the largest carnivores until the rise of the tyrranosaurids about fifty million years later.

"The genus Allosaurus has been discovered in Upper Jurassic sediments (160 million years ago) in the U.S. "
