摘要: The nonmarine Permo-Jurassic deposits of the Karoo Supergroup South Africa have long been a world standard for tetrapod biostratigraphy. Recent and ongoing research is revising palaeoflora palaeofauna these sedimentary strata with an unprecedented level stratigraphic precision. This work has shown that: Permian palynomorphs are useful correlating time-equivalent lithostratigraphic units in different sectors basin; that there marked end-Guadalupian diversity drop tetrapods; Dicynodon Assemblage Zone can be subdivided, should renamed as Daptocephalus Zone; Cynognathus robust threefold subdivision; name Euskelosaurus Range invalid replaced. work, together new radiometric dates from Supergroup, dramatically enhanced our understanding timing major evolutionary events terrestrial ecosystems provides strong evidence tectonic controls on accommodation sedimentation Basin during Permo-Jurassic, within overall flexural basinal setting.
