11-Million-Year-Old Weird Worm Lizard Discovered

11-Million-Year-Old Weird WormThey look like snakes, but don’t be fooled: Legless, slithering amphisbaenians are more closely related to lizards than to boa constrictors.

Now, the first complete skull of the ancestor of today’s bizarre “worm lizards” reveals that these strange reptiles have been largely unchanged for at least 11 million years. The fossil skull, discovered in Spain, is only 0.44 inches (11.2 millimeters long), but represents a new species, Blanus mendezi.

This family, known as blanids, includes the only worm lizards found on land in Europe, said study researcher Arnau Bolet, a doctoral student at the Institut Català de Paleontologia Miquel Crusafont in Barcelona.

Their fossil record was until now limited to isolated and usually fragmented bones,” Bolet told Live Science in an email. “Thus, the study of a complete fossil skull more than 11 million years old was an unprecedented opportunity.”
