Its closest living relatives among these appear to be the peculiar and nearly extinct Smith's dwarf chameleon from mountainous habitat, and especially the southern dwarf chameleon. The Karoo dwarf chameleon may actually be a subspecies of the latter; there appears to be significant gene flow between the two. Karoo dwarf chameleon The Karoo dwarf chameleon ("Bradypodion karrooicum") is a chameleon native to South Africa. It is about 14 cm (6 in) long, mostly colored
Karoo Group (i.e. the oldest layer of the Cape Supergroup). The valley floor is covered, in the main, by the next (younger) layer of the Supergroup, namely the much softer Bokkeveld shales. The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was
