Herrerasaurus was one of the earliest dinosaurs ever to be discovered. It had hinged jaws and it could open it's mouth wide to consume 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 20 feet long, 10 feet tall, and lived in Argentina approximately 231 million years ago in the Late Triassic period. It was the biggest dinosaur predator of its time. Unlike the other giant killers, Herreasaurus stood on it's hind legs. It was a very fierce predator.
