Anura (frogs and toads) constitute over 90% of living amphibian diversity. Recent timetree constructions have shown that their diversification was a highly episodic process, with establishment of the major clades in three periods: Triassic (251-200 million years ago, Ma), end of Jurassic to early Cretaceous (~150-100 Ma), and end Cretaceous to early Paleogene (~70-50 Ma). The early diversification of anurans predated the initial north-south breakup of Pangaea, and resulted in distinct assemblages in both hemispheres. The subsequent radiation of neobatrachian frogs has been largely determined by Gondwanan fragmentation and resulted in recurrent patterns of continent-scale endemism.
