Reptilians survive from the age of the Saurians, but if many look Ancient that’s because their early and sometimes relatively recent adaptations to widely varied conditions worldwide still work admirably. Examples include lizards like the giant Komodo dragon, still top-dog on his Indonesian island, the feared crocodilian hunters, color-changing chameleons and snake species fitted for most (warm) ecosystems. The same goes for amphibians, including numerous specialized (tree) frogs and toads. Both groups are cold-blooded, hence vulnerable while warming up.
