Daye Formation (China) | |
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.
The Daye Formation hosts the Guiyang biota, as of 2023 the earliest known Mesozoic lagerstätte.[3]
