One of the key faunal transitions in Earth history occurred after the
Permo-Triassic mass extinction (ca. 252.2 Ma), when the previously obscure
archosauromorphs (which include crocodylians, dinosaurs, and birds) become
the dominant terrestrial vertebrates. Here, we place all known middle
Permian–early Late Triassic archosauromorph species into an explicit
phylogenetic context, and quantify biodiversity change through this
interval. Our results indicate the following sequence of diversification:
a morphologically conservative and globally distributed post-extinction
‘disaster fauna’; a major but cryptic and poorly sampled phylogenetic
diversification with significantly elevated evolutionary rates; and a
marked increase in species counts, abundance, and disparity
contemporaneous with global ecosystem stabilisation some 5 million years
after the extinction. This multiphase event transformed global ecosystems,
with far-reaching consequences for Mesozoic and modern faunas.
