Allosaurus

Allosaurus ("different lizard") was a Late Jurassic predator. It is the most well-know large theropod.

Iberomesornis's Idea
Allosaurus should have a forest-grassland mix, with a few pieces of carrion around. Allosaurus was also a great sprinter, so space is needed. Mouth exercising, like chewing ballls, would help the hathlings develop the jaw muscles, letting it to open its jaw wide, like a snake. Prey should always be delivered only to adults, that would later feed their sons. Allosaurus paddocks would require a "lair" where other pack members and young Allosaurus would rest.
