Question

what was the first dinosaur in world​

Answer 1

A wonky beast about the size of a Labrador retriever with a long neck and lengthy tail may be the world's earliest known dinosaur, say researchers who analyzed fossilized bones discovered in Tanzania in the 1930s. Now named Nyasasaurus parringtoni, the dinosaur would've walked a different Earth from today.

Answer 2

The very first dinosaurs. The oldest dinosaurs yet discovered date back nearly 230m years to the Late Triassic epoch. Fossils of Herrerasaurus and Eoraptor were discovered in Argentina; both were bipedal carnivores (meat-eaters that walked on two legs), and small in comparison to the giant dinosaurs that would follow.
