Herrerasaurus Facts for Kids
Herrerasaurus was one of the earliest known dinosaurs, living in Late Triassic Argentina long before T. rex. It was not a giant Jurassic monster, but a fast, sharp-toothed predator from a time when dinosaurs were still rare. Fossils from the Ischigualasto Formation help scientists study how the first dinosaurs began to take shape.
