Squamates

 * Squamata

Classification
Historically, the order Squamata has been divided into three suborders:
 * Lacertilia, the lizards
 * Serpentes, the snakes (see also Ophidia)
 * Amphisbaenia, the worm lizards

Of these, the lizards form a paraphyletic group, since "lizards" excludes the subclades of snakes and amphisbaenians. Studies of squamate relationships using molecular biology have found several distinct lineages, though the specific details of their interrelationships vary from one study to the next. One example of a modern classification of the squamates  found the following relationships:

Iguanias

Below is a cladogram from the phylogenetic analysis of Daza et al. (2012) (a morphological analysis), showing the interrelationships of extinct and living iguanians:
