In the lizard family Cordylidae, for instance, a single divergence from oviparity (egg-laying) long ago resulted in a viviparous clade including almost all of the living species of the family.
This event is poorly understood and accompanied or closely followed a major life-style transformation in the cordyliformes (i.e., from a terrestrial active foraging ancestor to a rock-dwelling sit-and-wait forager).

They are restricted to southern and eastern Africa and Madagascar and include about 10 genera and more than 50 species, which have spiny or platelike protective scales covering the body.

First, qualitative observation suggests that trait linkages may exist in Cordylidae, e.g., that species with short legs often also have heavy armor.
Second, these morphological data may be combined with behavioral studies (particularly of escape behavior) to investigate relationships between behavior and morphology.
Third, some researchers have speculated that morphologically similar species within Cordylidae may have evolved from events of convergent evolution.

We report here the first unequivocal record of a pre-Late Pleistocene lizard from the island of Madagascar, based on a nearly complete lower jaw, elements of both the pectoral and pelvic girdles, several vertebrae and ribs, and numerous osteoderms of what is presumed to be a single individual.
The specimen, recovered from the Upper Cretaceous (Maastrichtian) Anembalemba Member, Maevarano Formation, Mahajanga Basin, northwestern Madagascar, is identified as a scincoid scincomorph and, more specifically, a new genus and species of ?Cordylidae (Cordyliformes), based on a combination of gnathic, dental, and postcranial characters.
If the new taxon is correctly attributed to the Cordylidae, it constitutes a significant temporal and geographic range extension for the clade since cordylids have no definite representatives in the fossil record and extant forms are restricted to the sub-Saharan portion of mainland Africa.
