It lived in a warm, wet floodplain with forests of ferns and giant conifers, alongside other early dinosaurs like Herrerasaurus and Eoraptor.1
The only known fossil of Sanjuansaurus was found in an area of just one square meter, suggesting all the bones came from a single animal.2
Sanjuansaurus was about the same size as a medium-sized Herrerasaurus, and slightly larger than Staurikosaurus.2
The name Sanjuansaurus honors San Juan Province in Argentina, where the fossil was discovered.1
Scientists think Sanjuansaurus was a fast runner because its leg bones were long and slender, built for speed.2
