Mexican Beaded Lizard

The beaded lizard has one close living relative, the Gila monster (H. suspectum), as well as many extinct relatives in the Helodermatidae, whose evolutionary history may be traced back to the Cretaceous period. The genus Heloderma has existed since the Miocene, when H. texana ranged over most of North America. Because the helodermatids have remained relatively unchanged morphologically, they are occasionally regarded as living fossils.
