'''''Floridachoerus olseni''''' is an extinct peccary that lived during the Hemingfordian age of the Early Miocene, and was endemic to North America. ''F. olseni'' was in existence for approximately {{Mya|20.43-15.97|million years}}.<ref>[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=46551|T.E. White, J. Alroy at Fossilworks]</ref> Remains of this extinct mammal were located at the fossil rich Thomas Farm site in Gilchrist County, Florida (two collections) and Toledo Bend site, Newton County, Texas.<ref>[https://web.archive.org/web/20230817063241/http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&taxon_no=46551&max_interval=Miocene&country=United%20States&state=Texas&is_real_user=1&basic=yes&type=view&match_subgenera=1 Toledo Bend collection, Fossilworks]</ref> ''Floridachoerus olseni'' was named after Stanley.

==Lithology of sites== *'''Thomas Farm site''': An ancient sinkhole with an associated cave system not unusual for N. Florida. It's within a calcareous sandstone and blue claystone. The fossils are from multiple horizons including a joint clay; a layer of clayballs, lime sand; a bed of limestone, boulders with gravel and lime sand matrix; and a laminated bluish clay. Most of the material is from the lime sand. The biochronology points to an early Hemingfordian origin through the presence of the ancient bear, ''Phoberocyon'', the mustelid ''Leptarctus'', the rhino ''Floridaceras'', and ''Metatomarctus'', a canid.<ref>[http://www.flmnh.ufl.edu/vertpaleo/thomasfarm.htm Florida Museum of Natural History, Thomas Farm paleontological site]</ref> The Thomas Farm site is located on the Alachua Formation. *'''Toledo Bend site''': A coarse palaeochannel fill; a conglomerate likely from an episode of violent flood mixing of materials. (Albright, 1999). Also recovered with several mammals including two other Tayassuidae (''Marshochoerus'', ''Hesperhys'') three species of rhino, two species of horse, the ''Dinohyus'', ''Daphoedon'', and ''Nothokemas''.
