Wumengosaurus is an extinct aquatic reptile from the Middle Triassic (late Anisian stage) Guanling Formation of Guizhou, southwestern China. It was originally described as a basal eosauropterygian and usually is recovered as such by phylogenetic analyses,[1][2][3] although one phylogeny has placed it as the sister taxon to Ichthyosauromorpha while refraining from a formal re-positioning.[4] It was a relatively small reptile, measuring 95.5–130.5 cm (3.13–4.28 ft) in total body length.[1]
In 2021, Qin et al. described an additional specimen from Guizhou (Panzhou District) as a new species of Wumengosaurus, W. rotundicarpus.[5]
