摘要

•Measured δ13C signatures for n-alkanes, hopanes, C29 sterane, pristane, and phytane.•Green algal C29 sterane δ13C closely matched δ13CTOC.•Large (∼10‰) variations in δ13CTOC between sites attributed to environmental changes.•Late Ediacaran epicontinental sea environments on Baltica had high regional heterogeneity.
