Evolution of Atmospheric O2 Through the Phanerozoic, Revisited
An oxygen-rich atmosphere is essential for complex animals. The early Earth had an anoxic
atmosphere, and understanding the rise and maintenance of high O2 levels is critical for …

A revised definition for copal and its significance for palaeontological and Anthropocene biodiversity-loss studies
The early fossilization steps of natural resins and associated terminology are a subject of
constant debate. Copal and resin are archives of palaeontological and historical information …

Global increase in plant carbon isotope fractionation following the Last Glacial Maximum caused by increase in atmospheric pCO2
Abstract Changes in the carbon isotope composition of terrestrial plant tissue (δ13C) are
widely cited for evidence of shifts in climate, vegetation, or atmospheric chemistry across a …

Organic petrography, biomarkers, and stable isotope (δ13C, δD, δ15N, δ18O) compositions of liptinite-rich coals
Liptinite-rich coals were evaluated using organic petrography, biomarkers, and stable
isotopes to investigate their origin and paleoenvironmental significance, particularly, to …

Long-term climate forcing by atmospheric oxygen concentrations
The percentage of oxygen in Earth's atmosphere varied between 10% and 35% throughout
the Phanerozoic. These changes have been linked to the evolution, radiation, and size of …

Distinct origins for Rovno and Baltic ambers: Evidence from carbon and hydrogen stable isotopes
Ambers—fossilized plant resins—are a rich and unique source of paleoecological data due
to their ability to preserve soft body fossils. However, interpretations concerning their …
