The first of these occurred about one-third of the way through the period, during the early Jurassic. The major group of diapsids, the archosaurs (ruling reptiles) evolved in the later part of the Permian, and underwent a major adaptive radiation in the late Triassic. Mammals also evolved during the Triassic, at about the...
