Subgroups and genera

Neodiapsida is a clade, or major branch, of the reptilian family tree, typically defined as including all diapsids apart from some early primitive types known as the araeoscelidians. Modern reptiles and birds belong to the neodiapsid subclade Sauria.

The oldest known neodiapsids are Orovenator and Maiothisavros from the Early Permian of North America, around 290 million years old.[1][2]

Basal-non saurian neodiaspids were ancestrally lizard-like, but basal non-saurian neodiapsids include aquatic/amphibious taxa (

gliding lizard-like Weigeltisauridae,[4] as well as the Triassic chameleon-like drepanosaurs.[5] The position of the highly derived Mesozoic marine reptile groups Thalattosauria, Ichthyosauromorpha and Sauropterygia within Neodiapsida is uncertain, and they may lie within Sauria.[6]

Classification

The clade Neodiapsida was given a

Youngina capensis) than to Petrolacosaurus.[7] The cladogram presented here illustrates the "family tree" of reptiles, and follows a simplified version of the relationships found by M.S. Lee, in 2013.[8] All genetic studies have supported the hypothesis that turtles are diapsid reptiles; some have placed turtles within archosauromorpha,[8][9] or, more commonly, as a sister group to extant archosaurs.[10][11][12][13] though a few have recovered turtles as lepidosauromorphs instead.[14] The cladogram of Lee (2013) below used a combination of genetic (molecular) and fossil (morphological) data to obtain its results.[8]

This second cladogram is based on the 2017 study by Pritchard and Nesbitt.[15]
