Herrerasaurus was one of the earliest dinosaurs ever to be discovered. It had hinged jaws and it could open it's mouth wide to gobble up chunks of meat. It perfect serrated teeth like a saw. It also had short arm bones but it also had long hands.

Herrerasaurus means 'Herrera's Lizard' for the discoverer Don Victorino Herrera. Herrerasaurus grew to about 16.5feet long and lived in Argentina 225 million years ago in the Late Triassic period. It wasn't the bigger predator of it's time although other giants were not dinosaurus. They were in fact Crocodilians. Unlike the other giant killers, Herreasaurus stood on it's hind legs. It was a very fierce predator.
