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.

Get the aljoscha mug.Most hilarious person you will ever meet. Sweet, kind, of course funny, and cute, although he might admit to none of those things. Unbelievably caring and willing to stand up for what he believes in, stick up for friends/girlfriend, and not afraid to just have fun no matter what anyone thinks. Very intelligent, sometimes even thinks too much into things. Has a lot of friends, but loses temper easily when it comes to certain things. Mess with the people close to him? Watch out. Very protective and loving! And, overall, just an awesome person.
