Background The rich rodent assemblages from the Eocene–Oligocene deposits of the Jebel Qatrani Formation (Fayum Depression, Egypt) have important implications for our understanding of the origin and paleobiogeography of Hystricognathi, a diverse clad...

Ancient DNA of the pygmy marmoset type specimen Cebuella pygmaea (Spix, 1823) resolves a taxonomic conundrum (2021)
Journal Article

The pygmy marmoset, the smallest of the anthropoid primates, has a broad distribution in Western Amazonia. Recent studies using molecular and morphological data have identified two distinct species separated by the Napo and Solimões-Amazonas rivers....

Widespread loss of mammalian lineage and dietary diversity in the early Oligocene of Afro-Arabia (2021)
Journal Article

Diverse lines of geological and geochemical evidence indicate that the Eocene-Oligocene transition (EOT) marked the onset of a global cooling phase, rapid growth of the Antarctic ice sheet, and a worldwide drop in sea level. Paleontologists have esta... Read More about Widespread loss of mammalian lineage and dietary diversity in the early Oligocene of Afro-Arabia.

An early Oligocene age for the oldest known monkeys and rodents of South America (2021)
Journal Article
Campbell, K., O'Sullivan, P., Fleagle, J., de Vries, D., & Seiffert, E. (2021). An early Oligocene age for the oldest known monkeys and rodents of South America. Proceedings of the National Academy of Sciences, 118(37), e2105956118. https://doi.org/10.1073/pnas.2105956118

The Santa Rosa fossil locality in eastern Perú produced the first Paleogene vertebrate fauna from the Amazon Basin, including the oldest known monkeys from South America. This diverse paleofauna was originally assigned an Eocene age based largely on... Read More about An early Oligocene age for the oldest known monkeys and rodents of South America.

The evolution of mammalian brain size (2021)
Journal Article

Relative brain size has long been considered a reflection of cognitive capacities and has played a fundamental role in developing core theories in the life sciences. Yet, the notion that relative brain size validly represents selection on brain size... Read More about The evolution of mammalian brain size.
