Karoo Supergroup Malawi, as well as on other continents that were part of Gondwana. The basins in which it was deposited formed during the formation and breakup of Pangea. The type area of the Karoo Supergroup is the Great Karoo in South Africa, where the most extensive outcrops of the sequence are exposed. Its strata which consist mostly of shales and sandstones, record an almost continuous sequence of marine glacial to terrestrial deposition from the Late Carboniferous to the Early Jurassic. These accumulated in a retroarc foreland basin called the "main Karoo" Basin. This basin was formed by the subduction and orogenesis
Karoo the winter. Grasses are uncommon, making most of the biome unsuitable for grazing. The low rainfall, in fact, discourages most forms of agriculture. An exception is the thriving ostrich-farming industry in the Little Karoo, which is heavily dependent on supplementary feeding with lucerne. The difference between the Succulent Karoo biome and the Nama Karoo biome is that the former receives the little rain that falls as cyclonic rainfall in winter, which has less erosive power than the infrequent but violent summer thunderstorms of the Nama Karoo. Frost is also less common in the Succulent Karoo biome than in the Nama
