Abstract
New temnospondyl material is described on the basis of cranial and postcran ial remains from the Gai-As Formation of the Huab Basin, Namibia. An Early Permian age is indicated by U/Pb SHRIMP dating of zircons from fallout tuff beds occurring immediately above the temnospondyl remains. This material r epresents the oldest known amphibian with stereospondylous vertebrae and ha s implications for temnospondyl evolution, biogeography and Permo-Triassic Gondwanan basin development models.
