The theory is that many dinosaurs died because of the hot and dry season. First, there was a huge drought in the beginning. The coelophysis that were still alive discovered a few sickly fish swimming slowly back and forth in a puddle. Other fish bodies have already sunk into the mud. When a sudden rainstorm breaks the drought, a surge of water and mud flows over the riverbanks and down the valley. Coelophysis and other predators are trapped and drown.

Also, when the water dries up, they leave behind both the dinosaurs that had died a few days earlier in the drought and the newly drowned dinosaurs. Some are dumped in tangles, some lie alone, stretched out on the mud. The ones that lie in puddles begin to separate. Those outside the puddles
