The Karoo Basin is a large sedimentary basin in South Africa, known for its extensive Permian to Jurassic sedimentary rocks and rich fossil record, including early dinosaurs and synapsids. The basin is important in studying the Permian-Triassic extinction event, the evolution of early terrestrial ecosystems, and the development of large continental basins.
