(Mass extinction of land and sea biodiversity 250 million years ago not simultaneous, National Science Foundation)

An era of geological history which extends from the beginning of the Cambrian to the close of the Permian and is marked by the culmination of nearly all classes of invertebrates except the insects and in the later epochs of which seed-bearing plants, amphibians, and reptiles first appeared.
