Chinosaurus (Chinnus Maximus), also known as Chinosaurus Rex, is fearsome omnivorous dinosaur, belonging to the family of Ornithomimidae, that is known for lacking a chin (basically LeafyIsHere). Few specimens have survived to this day, roaming the earth and giving fear to the inhabitants of the planet as it usually gives out death threats (usually free of charge).
