Archaeal lipid biomarker constraints on the Paleocene-Eocene carbon isotope excursion

Archaeal lipid biomarker constraints on the Paleocene-Eocene carbon isotope excursion

The Paleocene-Eocene Thermal Maximum (c. 55 million years ago) was a period associated with massive carbon injection into the atmosphere, yet discrepancies in carbon isotope proxy records have led to substantial uncertainties in the source, scale, and timing of carbon emissions. Here, the authors pr...
