Vertebrate assemblages from the north-central Main Karoo Basin, South Africa, and their implications for mid-Permian biogeography

The rich fossil vertebrate record from the Beaufort Group, Main Karoo Basin, provides a global standard for mid-Permian to Mid-Triassic continental faunas. However, recent studies have demonstrated variability in the composition of contemporaneous faunas across Gondwana. This raises the question of how much the vertebrate faunas differ within the Karoo, where the taxonomic composition of vertebrate assemblage zones (AZs) is mostly considered to...
