Mammals, birds, and squamates (lizards, snakes, and relatives) are key
living vertebrates, and thus understanding their evolution underpins
important questions in biodiversity science. Whereas the origins of
mammals and birds are relatively well understood, the roots of squamates
have been obscure. Here, we report a modern-type lizard from the Late
Triassic of England [202 million years (Ma)], comprising a partial
skeleton, skull, and mandibles. It displays at least 15 unique squamate
traits and further shares unidentatan and anguimorph apomorphies. The new
discovery fixes the origin of crown Squamata as much older than had been
thought, and the revised dating shows substantial diversification of
modern-type squamates following the Carnian Pluvial Episode, 232 Ma ago.
