The Succulent Karoo biome runs along the West Coast, from approximately Lamberts Bay northwards to over 200 km into southern Namibia. It starts in the south just north of the Sandveld geographical region, about 250 km north of Cape Town, and continues through Namaqualand, the Richtersveld, immediately south of the Orange River, and on into the Namaqualand or Namaland region of southern Namibia. None of these regions is ever referred to, either geographically or locally,

These genera represent some of the extinct, mainly predinosaur, animals of the Karoo: Karoo Koppies hills are capped by hard, erosion-resistant dolerite sills. This is solidified lava that was forced under high
