Karoo dwarf chameleon no means closely related. Rather, the Karoo dwarf chameleon belongs to a group of mostly short-tailed drab "Bradypodion" species which mostly inhabit semiarid to arid habitats. 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 sediments. This exposed the dolerite sills, which were more resistant to erosion than the Karoo sediments, forming one of the most characteristic features of the Karoo landscape, namely the flat topped hills, called "Karoo Koppies". The geology of the region bears no resemblance to that of the Great Karoo (see the diagram on the left, of a NS geological cross-section through the Little and Great Karoos). The valley is an integral part of the Cape Fold Mountain Belt, with the two ranges on either side composed of extremely hard, erosion-resistant, quartzitic sandstone belonging to the 450- to 510-million-year-old Table Mountain
