Perchoerus is an extinct genus of suine from the Eocene and Oligocene of North America. Three species are known.{{cite book |last1=Prothero |first1=Donald R. |title=THE SYSTEMATICS OF NORTH AMERICAN PECCARIES (MAMMALIA: ARTIODACTYLA: TAYASSUIDAE) By · 2021 |date=2021 |publisher=New Mexico Museum of Natural History and Science |pages=6–8}}{{cite journal |last1=Prothero |first1=Donald R. |title=THE EARLY EVOLUTION OF THE NORTH AMERICAN PECCARIES |journal=Museum of Northern Arizona Bulletin |date=2009 |volume=65 |pages=509–542}} While often considered to be a peccary, other studies have recovered it to be a basal suine outside of either peccaries or Suidae.{{Cite journal |last1=Parisi Dutra |first1=Rodrigo |last2=Casali |first2=Daniel de Melo |last3=Missagia |first3=Rafaela Velloso |last4=Gasparini |first4=Germán Mariano |last5=Perini |first5=Fernando Araujo |last6=Cozzuol |first6=Mario Alberto |date=2016-09-13 |title=Phylogenetic Systematics of Peccaries (Tayassuidae: Artiodactyla) and a Classification of South American Tayassuids |url=http://dx.doi.org/10.1007/s10914-016-9347-8 |journal=Journal of Mammalian Evolution |volume=24 |issue=3 |pages=345–358 |doi=10.1007/s10914-016-9347-8 |issn=1064-7554|hdl=11336/54840 |hdl-access=free }} The oldest known species of Perchoerus is P. minor, which was only the size of a house cat. It is known from skull and tooth material.

The later P. nanus of the Orellan grew larger and is known from a skull and lower jaw. The latest and largest species was P. probus of the Oligocene (32-30 mya). It was much larger (about as big as living peccaries) and known from more remains than the other species.{{cite book |last1=Prothero |first1=Donald R. |last2=Williams |first2=Mary Persis |title=The Princeton Field Guide to Prehistoric Mammals |date=2016 |publisher=Princeton University Press |isbn=9781400884452 |pages=157–158}}

Palaeoecology

Low δ13C values from the teeth of P. probus suggest that it was an inhabitant of dense riparian habitats.{{Cite journal |last1=Boardman |first1=Grant S. |last2=Secord |first2=Ross |date=1 April 2013 |title=Stable isotope paleoecology of White River ungulates during the Eocene–Oligocene climate transition in northwestern Nebraska |url=https://www.sciencedirect.com/science/article/pii/S0031018213000862 |journal=Palaeogeography, Palaeoclimatology, Palaeoecology |language=en |volume=375 |pages=38–49 |doi=10.1016/j.palaeo.2013.02.010 |bibcode=2013PPP...375...38B |access-date=17 November 2024 |via=Elsevier Science Direct|url-access=subscription }}
