Well,” Ellie said. “We know animals have survived. Crocodiles are basically Triassic animals living in the present. Sharks are Triassic. So we know it has happened before.”.

The Triassic formation
The earliest period of the Mesozoic era, spanning the time between 248 and 213 million years ago The name Triassic refers to the threefold division of rocks of this age in Germany
Of the age of, or pertaining to, the Trias
A geological era lasting from approximately 250 to 213 million years ago
Triassic Period
Interval of geologic time, 248-206 million years ago, that marks the beginning of the Mesozoic Era. Many new vertebrates emerged during the Triassic, heralding the major changes that were to occur in both terrestrial and marine life forms during the Mesozoic Era. The seas became inhabited by large marine reptiles. On land, ancestral forms of various modern amphibians arose, as did reptiles such as turtles and crocodilians. By the Late Triassic, archosaurs were becoming more and more dominant, and the first true mammals, small shrewlike omnivores, evolved. Seed ferns dominated the flora of southern Gondwana, and gymnosperms, including conifers, cycads, and ginkgos, were common throughout much of Pangea
