Daye Formation

The Daye Formation is a geologic formation in South China, dating from the Induan up to the early Olenekian (early Triassic).[1][2] It is of interest as it spans the period immediately after the Permian-Triassic extinction event, the most severe mass extinction known in Earth history.
