A new ichnotaxonomic name for burrows in vertebrate coprolites from the Miocene Chesapeake Group of Maryland, U.S.A

Swiss Journal of Palaeontology, 2022
A new ichnotaxonomic name, Transexcrementum cuniculus , is applied to tubular (cylindrical) tunnelings in coprolites. The type series of T. cuniculus consists of burrowed vertebrate (probably crocodilian) coprolites that originate from the Miocene ...

Pre-Clovis occupation of the Americas identified by human fecal biomarkers in coprolites from Paisley Caves, Oregon

Science Advances, 2020
We unequivocally confirmed pre-Clovis human occupation of the western Great Basin using fecal lipid biomarkers and a new 14C date. When and how people first settled in the Americas is an ongoing area of research and debate.
