Guiyang biota (China)
The Guiyang biota is an exceptionally preserved Early Triassic (approximately 250.8 million years ago) fossil assemblage from the Daye Formation near Guiyang (China), discovered between 2015 and 2019[1] and first reported in 2023. It is the oldest known Mesozoic lagerstätte, and it provides evidence of the existence of a complex marine ecosystem shortly after the Permian–Triassic extinction event.[2]
