Paleoanguimorpha
Clade of lizards
From Wikipedia, the free encyclopedia
Paleoanguimorpha is a clade of anguimorphs comprising Shinisauria (represented today by shinisaurids) and Goannasauria (represented today by Varanoidea which includes the families Lanthanotidae and Varanidae).[1][2][3][4][5] Morphological studies in the past also classified helodermatids and pythonomorphs with the varanoids in the clade Platynota,[6][7] while the Chinese crocodile lizard was classified as a xenosaurid.[8] Current molecular work finds no support in these groupings and instead has found the helodermatids more related to Diploglossa in the sister clade Neoanguimorpha, while the Chinese crocodile lizard is the closest living relative to varanoids.[2][3] Pythonomorphs represented by snakes today are not closely related to varanoids and are instead a sister lineage to Anguimorpha and Iguania in the clade Toxicofera.[1][3]
