These dinosaurs were the ancestors of the biggest land animals ever.
Formally known as "Prosauropods" these inhabited most of the world, in the late Triassic and early Jurassic.
They were from 1,5 metres to 10 metres, and they had a strange theropodian (sometimes bipedal) look.
There has been found over 100 of Plateosaurus skeletons, a sign of pack behaviour such as seen in wildebeests

A Yunnanosaurus find included the skeleton of Dilophosaurus sinensis.
The predator's head was stuffed in between Yunnanosaurus's ribs, and it probably got stuck by the crest,
while feasting, and eventually drowned in the organs and blood.
