Poposaurus gracilis1
Poposaurus was an animal related to crocodiles and dinosaurs. It lived during the late Triassic period, about 216 million years ago.

Like theropod dinosaurs, Poposaurus walked on two legs rather than four. However it is more closely related to living crocodilians than to dinosaurs. Poposaurus was about 4 metres (13 ft) long, with the tail comprising about half the body length. It is estimated to have weighed around 60 to 75 kilograms (130 to 170 lb), with the largest individuals reaching 90 to 100 kilograms (200 to 220 lb).
