- Surprisingly for a large predator, Allosaurus had a relatively weak bite for its size. It most likely attacked prey by inflicting slashing-style injuries with its serrated teeth and then waiting for the animal to succumb to its wounds.
Allosaurus is often referred to as “the lion of the Jurassic” and was one of the most common carnivores of its day. There is considerable debate as to whether or not Allosaurus lived in packs. It is not uncommon to find fossil deposits containing multiple individuals, and some paleontologists cite bite marks on snouts as evidence for establishing hierarchy within a social group. However, others argue that this is evidence for intraspecific competition rather than sociality.
