The lizard was named Babibasiliscus alxi, where babi means “older male cousin” in Shoshone Native American – a tribute to the local heritage. Judging from the fossils, the lizard was likely two feet long, was active during the day and likely spent most of its time in trees. Like other casqueheads, the lizard has a ridge over its skull that likely made it look fiercer to its prey. Its teeth had three points suitable for eating snakes, lizards, fish, insects and plants. The larger cheekbones suggest it also hunted large prey.

Based on phylogenetic analysis Babibasiliscus is closely related to the modern genus Laemanctus, which includes the famous Jesus Lizard. The Jesus Lizard likes to live near water, that way, when it is frightened by an approaching predator it can get to the water and run across the surface. The lizards can run on water because they have a fringe of scales on their hind toes which makes little webs that can trap bubbles of air and water beneath their feet. This keeps them from sinking into the water if they run quickly enough across. When they do stop running they don’t mind taking a little swim. It’s not clear whether Babibasiliscus also skimmed water.
