Tent tortoise Tent tortoise The tent tortoise ("Psammobates tentorius") is a species of tortoise and one of three members of the genus, "Psammobates". Known locally as the Karoo tent tortoise, this highly variable species is found in the Karoo and semi-desert regions of Southern Africa. The Karoo tent tortoise occurs at very low densities throughout the Karoo and other semi-desert areas of southern Africa, extending from central Namibia almost to the southern coast of South Africa. Within this range, its population is very sparse and individuals are normally rare and widely separated. The species is also increasingly rare due to habitat destruction
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
