The Big Burp: A Bad Day in the Paleocene [PDF]
This lesson focuses on global warming and a possible connection with the Paleocene extinction event. Students will explore how a global warming episode associated with the release of methane from methane hydrate deposits could have been responsible for ...

PLoS ONE, 2014 The Paleocene-Eocene Thermal Maximum (PETM) is correlated with the first occurrences of earliest modern mammals in the Northern Hemisphere. The latest Paleocene Clarkforkian North American Land Mammal Age, that has yielded rodents and carnivorans, is the

An effective palynological preparation procedure using hydrogen peroxide [PDF]
, 2007 Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively).

Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]
, 2010 Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.

The spread of marine anoxia on the northern Tethys margin during the Paleocene-Eocene Thermal Maximum [PDF]
, 2014 Records of the paleoenvironmental changes that occurred during the Paleocene-Eocene Thermal Maximum (PETM) are preserved in sedimentary rocks along the margins of the former Tethys Ocean and Peri-Tethys.

The Anatomical Record, Volume 309, Issue 4, Page 1037-1060, April 2026.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Ecology and Evolution, Volume 16, Issue 4, April 2026.A newly generated large‐scale molecular phylogeny of true ladybirds (Coccinellini) clarifies their evolutionary relationships and supports a boreotropical origin in the Paleocene, with multiple independent southward dispersals. Ancestral diet reconstructions suggest an initial specialization on aphids, followed by expansions in host range and ...
