Description

Allosaurus was a large carnivorous dinosaur representing the Jurassic. The weight of the allosaurus is supposed with around 2 tons. For a body, it was the light head. There was the projection that lacrimal bone developed on the eyes and had three sharp nails on short forefoot. Various fossils of the growth process are found and help a study on growth of Theropoda.

The habits

It is thought that the allosaurus was the king who was in the top of the food chain in the times, the area where allosaurus inhabited. “The ichnolite of the allosaurus on the neck of apatosaurus” and “the fossil of the Stegosaurus which he chew, and the sign remained in unison with the alignment of teeth of the allosaurus” are found. From them, it is supposed that Allosaurus attacked the large grazing dinosaur.

A large number of fossils might be found in the same stratum, and the allosaurus might act in a group.
