Question

Which period spanned the time interval from 208 to 146 million years ago?

Answer 1

The Mesozoic era covers the time between two great extinctions: the Permian extinction that closed the Paleozoic era, and the Cretaceous extinction that ended the reign of the dinosaurs (as well as the Mesozoic). The Mesozoic era is divided into three geologic periods, the Triassic ( 245-208 million years ago), the Jurassic (208-146 million years ago), and the Cretaceous (146-65 million years ago).
The Mesozoic was the time of the beginning of the breakup of Pangaea about 225-200 million years ago, eventually fragmenting that supercontinent into the modern continents. This breakup had profound consequences for living things, as had the earlier formation of Pangaea during the later Paleozoic. The breakup continues today!

Answer 2

so the jurassic era (:
