Iguanomorpha is a clade of reptiles that includes the ancestors of modern lizards and snakes. It originated around 230 million years ago during the early Triassic period.
The earliest known member of Iguanomorpha is Hovasaurus, a small carnivorous reptile that lived during the early Triassic. Its discovery has helped scientists better understand the evolution of Iguanomorpha.
Iguanomorpha is characterized by its primitive skull and dental structure, which is distinct from other reptiles of the time. This unique characteristic has led scientists to believe that Iguanomorpha was a key group in the evolution of modern reptiles.
Iguanomorpha Details
The Iguania infraorder is a key part of the Iguanomorpha group.
The Iguania infraorder is further divided into two main categories: Acrodonta and Pleurodonta.
Acrodonta includes families with unique characteristics.
Pleurodonta, on the other hand, consists of American arboreal lizards, chuckwallas, and iguanas.
Here's a breakdown of the extant families within the Iguania infraorder:
- Infraorder Acrodonta
- Infraorder Pleurodonta – American arboreal lizards, chuckwallas, iguanas
