The data set includes stable oxygen isotope data measured on the non-labile (HCl-extractable) phosphorus fraction (δ18O-PO4), extracted from each 1 cm layer of sediment core. This sediment core (LG3A) was dated via correlation with a parallel core (LG3C) using 8 age-depth tie points, for which core chronology was established by analysing 210Pb activity at the British Geological Survey Inorganic Geochemistry Laboratories.

Lagerstatten fossil occurrence data for six Triassic marine communities following the Permian-Triassic mass extinction. Also included are ecological trait data and feeding rules needed to parameterise food web model - PFIM (Paleo Food web Inference Model). See Dunhill et al. 2024, Nat Comms, https://www.nature.com/articles/s41467-024-53000-2) for method info. The six Triassic marine communities are; Dienerian, Guiyang, South China Early Spathian, Paris, southeastern Idaho, USA Spathian, Chaohu, Anhui Province, South China Anisian, Luoping, Yunnan, China Ladinian, Xingyi, Guizhou, China Carnian, Guanling, China
