Lipid taphonomy in the Proterozoic and the effect of microbial mats on biomarker preservation

Pawlowska, Maria M; Butterfield, Nicholas J; Brocks, Jochen


The pre-Ediacaran biomarker record has several characteristic features that distinguish it from its Phanerozoic counterpart, including high concentrations of unresolved complex mixture (UCM), low concentrations or absence of eukaryotic steranes, and a conspicuous carbon isotopic enrichment of n-alkyl lipids relative to bulk sedimentary carbon. We propose that these derive from a common, non-actualistic taphonomy based on the pervasive presence of microbial mats prior to the "Cambrian substrate...[Show more]
