Herrerasaurus ischigualastensis” (and detail), by Vlad Konstantinov (~Swordlord3d) for SOL 90 S.L. publishing house.

“Although Herrerasaurus shared the body shape of the large carnivorous dinosaurs, it lived about 230 million years ago, a time when dinosaurs were small and insignificant. It was the time of non-dinosaurian reptiles, not dinosaurs, and a major turning point in the Earth’s ecology." Wikipedia.
