'Jesus Lizard' First Walked on Water in Wyoming

Seventeen million years after dinosaurs became extinct, the world’s first known Jesus lizard walked on water in Wyoming, according to a new study.

The agile reptile, described in the journal PLOS ONE, provides clues on how Jesus lizards evolved, and what their early habitats were like. Such lizards are still alive today, with the group (Corytophanidae) including such well-known members as iguanas and chameleons.

The new fossil species, unearthed appropriately in what’s known as the Lucky Lizard Locality of Uinta County, Wyo., has been named Babibasiliscus alxi. Author Jack Conrad of the American Museum of Natural History explained that “Babi” is a Shoshone Native American word meaning “older male cousin.”

“The generic name is meant to honor the Shoshone people who originally inhabited the areas in which the specimen was discovered,” he wrote, adding that the inclusion of the term for “cousin” refers to the relationship of the animal with other Jesus lizards.

Conrad said that Wyoming at the time had a climate matching today’s tropics. The newly discovered lizard used to skim the surfaces of lush, watery habitats there.

The lizard’s fossils suggest that, when alive, it was around 2 feet long. Conrad believes the Jesus lizard was active during the day and spent a lot of time in trees.

A ridge of bone on the skull gave the lizard an angry look while providing shade for its eyes. The look must have terrified prey, which for this predatory lizard was ample. Conrad noted that each of its small teeth had three points suitable for eating snakes, lizards, fish, insects and plants.

The lizard also had large cheekbones, which suggest it could enjoy larger prey items as well.
