Anguimorpha
Sign in to saveThe Anguimorpha is a suborder of squamates. The group was named by Fürbringer in 1900 to include all autarchoglossans closer to Varanus and Anguis than Scincus. These lizards, along with iguanians and snakes, constitute the proposed "venom clade" Toxicofera of all venomous reptiles.

The Anguimorpha is a suborder of squamates. The group was named by Fürbringer in 1900 to include all autarchoglossans closer to Varanus and Anguis than Scincus. These lizards, along with iguanians and snakes, constitute the proposed "venom clade" Toxicofera of all venomous reptiles.
== Evolution == The oldest widely accepted member of Anguimorpha is Dorsetisaurus from the Late Jurassic of Europe and North America. In 2022, the genus Cryptovaranoides was described from the latest Triassic (Rhaetian) of England. Cryptovaranoides was recovered in the study as a crown-group anguimorph, and therefore the oldest crown group-squamate, 35 million years older than any previously known crown-group squamate. However, a 2023 study found that Cryptovaranoides most likely represents an archosauromorph that was only distantly related to squamates.
