Oxytropidoceras posted a topic in Fossil News
Orbit of Doom: The Surprising Connection Between Earth’s Orbital Patterns and an Ancient Warming Event, SciTechDaily, Pennsylvania State University, January 15, 2023 The open access paper is: Li, M., Bralower, T.J., Kump, L.R., Self-Trail, J.M., Zachos, J.C., Rush, W.D. and Robinson, M.M., 2022. Astrochronology of the Paleocene-Eocene Thermal Maximum on the Atlantic Coastal Plain. Nature communications, 13(1), pp.1-13. Another explanation for the PETM is: New imaging finds trigger for massive global warming 56 million years ago 56 million years ago, hot magma scorched the sediments under the Atlantic seafloor.
