Scientific American — Skinks, Skinks, Skinks Fossils indicate skinks as a whole are a fairly old group of lizards, the oldest specimens attributed to the group dating to the Lower Cretaceous. The vast majority of early fossil representatives of the group consists of jaw fragments alone. These are certainly from skink-like lizards (from the major lizard group termed Scincomorpha), but they might not all be from skinks proper, and some have been suggested to actually represent other groups (like the armadillo lizards or cordylids, a scincomorph group that also has a possible Cretaceous fossil record). Definite fossil members of modern groups – like blue-tongued skinks – are present in the Miocene.
