Ravager

An allosaurus that went through intensive genetic manipulation during embryonic stage of life. Mutations gave the Specimen a hardened carapace throughout its body that is  resistant to  small arms fire and attacks from aggressive fauna. Specimen also sports a maw full of teeth jutting out randomly akin to crocodilians (possible dna donor). Because of this adaption the subject can open its maw wider then any known unmutated allosaurus specimen and slam its jaws with an incredible force.
