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.

From the album: Fossil Amber and Copal: Worldwide Localities
Coleoptera with exuded gas bubbles; these are likely methane, and could be the by-product of methanogenic bacteria inside a xylophagous (wood-eating) species. Some adult members of the Cetoniinae subfamily (family: Scarabaeidae) are xylophagous and known to produce methane; while this is known from Recent species, it's possible such characteristics could be found in extinct members of the Scarabaeidae or Scarabaeoidea (superfamily). This inclusion is contained in the same specimen depicting pholadid crypts. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar. This image was captured using a HAYEAR HY-1070 microscope.© Kaegen Lau
