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 (crater) of its craters exceeds the critical crater diameter. This would explain the crowding of giant craters, since none of these would result in global degradation. Indeed, if Karoo, at 33 km diameter, represents D and resurfaced the asteroid, then the 5 or more other giant impacts must have happened subsequently, which is highly unusual given that they are in fact almost just as large. Thus α = 1.33 from Fig. 2a is likely a lower limit on Mathilde’s attenuation. Karoo (crater) Karoo is an impact crater on the Asteroid 253 Mathilde, named for the Great Karoo Basin, a coal basin
