The Department of Biological Sciences had four affiliated students offered a Graduate Research Fellowship on behalf of the U.S. National Science Foundation (NSF). The NSF announced recipients of the 2026 Graduate Research Fellowship Program awards on April 13.

Findings help clarify the biogeographic history of the earliest primate relatives and highlight the importance of continued fossil exploration in understudied regions.

A sediment-washing “bubbler” helped researchers recover 65.5-million-year-old teeth that illuminate how early primate relatives spread after the mass extinction.

Findings help clarify the biogeographic history of the earliest primate relatives and highlight the importance of continued fossil exploration in understudied regions.

Fossils of the earliest known euarchontan mammals, purgatoriid plesiadapiforms, first appear during the aftermath of the Cretaceous/Paleogene mass extinction. The oldest and most basally branching ...

The Picrodontidae from the middle Palaeocene of North America are enigmatic placental mammals that were allied with various mammalian groups but are generally now considered to have close affinities t...

New Findings Illuminate Ancient Species and its Evolutionary Connections to Modern-Day Humans.

Their fur may not have been flashy, but it served a purpose.

Palaechthonids are a likely paraphyletic or polyphyletic assemblage of dentally plesiomorphic plesiadapiforms known from the Paleocene of North Americ…
