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]
