5.
Members of the genus " Heloderma " have many extinct relatives in the Helodermatidae whose evolutionary history may be traced back to the Cretaceous period, such as " Estesia ".
6.
In Ecuador " Centrolene heloderma " has disappeared from two known locations ( including the type locality where it was last seen in 1979 ) and is now only known from one location.
7.
This animal is very interesting, not only because it's close to the lineage of modern Gila monsters ( " Heloderma " ), but also because its dentition shows evidence that it was venomous.
8.
In contrast to the normal drab coloration of most reptiles, the lizards of the genus " Heloderma " ( the Gila monster and the beaded lizard ) and many of the coral snakes have high-contrast warning coloration, warning potential predators they are venomous.
9.
This location is one of the few places in North America where the fringe-toed lizard ( " Uma inornata " ) is distributed, in addition to being the western limit for the distribution of the Gila monster ( " Heloderma suspectum " ).
10.
The genus " Heloderma " has existed since the Miocene, when " H . texana " lived, and fragments of osteoderms from the Gila monster have been found in late Pleistocene ( 10, 000 8, 000 years ago ) deposits near Las Vegas, Nevada.
