Supplementary data of Meso-Neoproterozoic diversification of crown-group eukaryotes was not accompanied by an oxygenation event

Samples were collected from newly exposed road cuts at the Shennongding, Tiechanghe, and Guanmenshan sections in Hubei Province, South China, as well as the Yuanjiagou section in Liaoning Province, North China. A total of 84 carbonate samples were collected from the Luanshigou, Dawokeng, Kuangshishan, Taizi, Yemahe, Wenshuihe, and Shicaohe formations in the Shennongjia Group, along with 67 carbonate samples from the Nanguanling and Ganjingzi formations in the Wuhangshan Group, and subsequently analyzed. Additionally, two compiled datasets provide information on Ce anomalies in carbonate rocks and the species richness of microfossils and macrofossils during the mid-Proterozoic. Table S1 presents rare earth element and carbon-oxygen isotope data from the Shennongjia Group and the Wuhangshan Group. Table S2 provides a compiled dataset of carbonate Ce anomalies spanning from 1800 Ma to 700 Ma. Table S3 provides a compiled dataset of microfossils and macrofossils spanning from 1800 Ma to 700 Ma.

本次研究样本采集自中国华南湖北省神农顶、铁厂河、关门山剖面以及中国华北辽宁省元家沟剖面的新近出露路堑。共计采集神农架群（Shennongjia Group）栾石沟组、大窝坑组、匡什山组、太子组、野马河组、温水河组及石槽河组碳酸盐岩样品84件，另采集武当山群（Wuhangshan Group）南关岭组与甘井子组碳酸盐岩样品67件，所有样品均完成后续分析测试。此外，本次研究整合了两套数据集，分别涵盖中元古代碳酸盐岩的铈异常（Ce anomaly）数据以及微体化石与宏体化石的物种丰度信息。附表S1列出了神农架群与武当山群的稀土元素及碳、氧同位素数据。附表S2提供了一套整合后的碳酸盐岩铈异常数据集，时间跨度为1800 Ma至700 Ma。附表S3提供了一套整合后的微体化石与宏体化石数据集，时间跨度为1800 Ma至700 Ma。
