Description

Herrerasaurus was a small carnivore from the Late Triassic Period, one of the oldest carnivores known. This dinosaur had a flexible jaw that allowed it to grip on to its prey. Based on its size, it likely hunted small and medium herbivores. Fossil evidence suggests that this dinosaur was capable of digesting bone.

Discovery

The first Herrerasaurus specimens were discovered in 1959 by Andean goatherd Victorino Herrera. Herrera spotted the fossils in surface level rock of the Ischigualasto Formation near the city of San Juan, Argentina. Paleontologist Osvaldo Reig named the dinosaur after Herrera, and initially classified it as a Carnosaur, the group that contains, among others, Carcharodontosaurus, Allosaurus, and Metriacanthosaurus. The fragmentary nature of the initial specimens made a conclusive classification difficult, but in 1988, a near complete skeleton was discovered, again in Argentina. Since this discovery, Herrerasaurus has been classified as completely distinct from theropods, despite superficial similarities.

Paleoecology

The Ischigualasto Formation was likely a warm, humid, forest-covered floodplain, subject to volcanic activity and strong rainy seasons. Ferns, horsetails, and giant conifers would have been common plants.
