The main Karoo Basin of South Africa contains the most abundant, diverse, and time expansive record of terrestrial vertebrates around the Palaeozoic-Mesozoic transition. This 10 km thick sedimentary succession accumulated in a large intracratonic, retro-arc, foreland basin (Johnson 1991; Catuneanu et al. 2005) in front of the rising Cape Fold Belt portion of the Gondwanide Mountain range that fringed the southern margin of Gondwana. Today, rocks of the Karoo Supergroup have a spatial distribution of some 300 000 km² (Smith 1990), which is more than one-half the land surface of South Africa. They were...
