From the small primitive bi-pedal predator of Triassic NW Argentina. Herrerasaurus was one of the earliest dinosaurs. Its name means “Herrera’s lizard”, after the rancher who discovered the first specimen.

Herrerasaurus or Herrerasaurus ischigualastensis was a lightly built bipedal carnivore with a long tail and a relatively small head. Adults had skulls up to 22 in. long and were up to 20 ft. in total length and 770 lbs. in weight.

Herrerasaurus or Herrerasaurus ischigualastensis had a long, narrow skull that lacked nearly all the specializations that characterized later dinosaurs, and more closely resembled those of more primitive archosaurs such as Euparkeria and had five pairs of skull openings in its skull, two pairs of which were for the eyes and nostrils.

Between the eyes and the nostrils were two antorbital fenestrae and a pair of tiny, 0.39 in. slit like holes called promaxillary fenestrae.

Herrerasaurus ischigualastensis had a flexible joint in the lower jaw that could slide back and forth to deliver a grasping bite. This cranial specialization is unusual among dinosaurs but has evolved independently in some lizards. The rear of the lower jaw also had a small hole. The jaws were equipped with large serrated teeth for biting and eating flesh, and the neck was slender and flexible.

Herrerasaurus was fully bipedal. It had strong hind limbs with short thighs and rather long feet, indicating that it was likely a swift runner. The forelimbs of were less than half the length of its hind limbs.

The upper arm and forearm were short, while the manus (hand) was elongated. The first two fingers and the thumb ended in curved, sharp claws for grasping prey. The fourth and fifth digits were small stubs without claws.
