<dinofyi-dinosaur slug="herrerasaurus"></dinofyi-dinosaur>Herrerasaurus was one of the earliest known dinosaurs, from the Late Triassic. It was a bipedal predator with a flexible lower jaw joint. Its placement in dinosaur classification has been debated, but most analyses place it as an early saurischian.

Diet & Feeding
Herrerasaurus was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.
Time Period
Herrerasaurus lived during the Triassic Late period of the Mesozoic Era, approximately 237.0 to 201.4 million years ago.
The first true dinosaurs appeared during the late Triassic, including early theropods like Eoraptor and Herrerasaurus. Dinosaurs were still small and not yet dominant. The period ended with the Triassic-Jurassic extinction event.
