Genetics re-establish the utility of 2-methylhopanes as cyanobacterial biomarkers before 750 million years ago

2022-11-07

Abstract excerpt

<title>Abstract</title> <p>Fossilized lipids offer one of only few windows into ancient ecosystems. The utility of such biomarkers is determined by the phylogenetic distribution of lipid biosynthetic capabilities in extant organisms and extrapolation of this information into the past. 2-Methylhopanes in sedimentary rocks were once used to infer the importance of Cyanobacteria as primary producers in the geologica...
