Eolacertilia ("dawn lizards") is an extinct clade of lepidosauriform diapsid reptiles known from the Late Permian to the Late Triassic. It is uncertain as to whether they are a natural group and it has been suggested that they form a "waste basket" taxon. Currently, the only members of the group are Paliguana and Kuehneosauridae.[2] Other genera were transferred to basal groups within Diapsida (such as Palaeagama and Saurosternon), Archosauromorpha (Tanystropheus and Cteniogenys).[3]
