Barbaturex
''Barbaturex'' is an extinct genus of giant herbivorous iguanian lizards from the Eocene of Myanmar. It is represented by a single species, ''Barbaturex morrisoni'', which is known from several partial dentaries (lower jaw bones) and a fused pair of frontals, two bones that form part of the top of the skull. Based on the size of these bones, ''Barbaturex morrisoni'' is estimated to have been about from snout to vent, and possibly up to including the tail. ''Barbaturex morrisoni'' was named after The Doors frontman Jim Morrison, a play on his epithet "The Lizard King". The genus's name is a portmanteau of the Latin words ''Barbatus'' and ''rex'', meaning "bearded king", in reference to ridges along the mandible and the lizard's large size.〔 ==Relationships== ''Barbaturex'' belongs to a major group of lizards called Iguania, represented today by iguanas, chameleons, and agamids. It belongs to a clade or evolutionary grouping of iguanians called Acrodonta. Like other members of Acrodonta, ''Barbaturex'' has an acrodont dentition at the back of its jaws, meaning that the teeth are completely fused with the jaw bone, and a pleurodont dentition at the front of its jaws, meaning that the teeth are fused with the inside surface of the jaw bone. A phylogenetic analysis published with its initial description placed ''Barbaturex'' as the sister taxon or closest relative of the group Uromasticinae, which includes the living ''Uromastyx'', a genus of short-skulled herbivorous lizards. Below is a cladogram showing the relationship of ''Barbaturex'' to other members of Acrodonta:〔 }} |2= }} }} }} }} }} }}
