Castoroides ohioensis localities occur throughout the eastern two 
thirds of North America, and are concentrated in the area south of the 
Great Lakes (Dallman 1969). The species has also been reported in the 
Southeast, including Georgia, South Carolina (Hay 1923), Tennessee 
(Parmalee et al. 1976) and Florida (Martin 1969). 
Castor canadensis (Kuhl) — beaver 
Material.— HS. 104, right femur. 
Remarks.— Although the species is a common constituent of fossil 
faunas, this specimen may be modern. 
Family Hydrochoeridae 
Neochoerus pinckneyi (Hay) — giant capybara 
Material. — Ch M . PV 2439, RM 3 ; ChM.PV2440, RI 1 . 
Remarks.— This giant capybara was described by Hay (1923) as 
Hydrodchoerus pinckneyi on the basis of a left upper third molar from the 
Charleston area with which ChM.PV2439 closely compares. In 1927 Hay 
erected Neochoerus for the species. It is morphologically similar to the 
living Hydrochoerus, but of larger size. Capybara remains are common in 
Florida (Simpson 1930; Webb 1974).

Suborder Odontoceti 
Family Delphinidae 
Tursiops cf. T. truncatus (Montague) — Atlantic bottlenose dolphin

Suborder Mysticeti 
Family Balaenopteridae, gen. et sp. indet. 
A vertebral fragment (ChM.PV2431) and an auditory bulla 
(ChM.PV2433) represent balaenopterids of indeterminate genus or 
genera. 
Order Cetacea, gen. et sp. indet. 
Three vertebral fragments (ChM.PV23 18-2320) and two auditory 
bullae (ChM.PV2435 and HS.A-90) are of cetacean origin, but generic 
identifications remain to be determined.
