Taxonomy
editFloridaceras was named by Wood (1964). Its type is Floridaceras whitei. It was assigned to Rhinocerotidae by Wood (1964) and Carroll (1988); and to Aceratheriinae by Prothero (1998).[1]
Fossil distribution
editThe only site known is the Thomas Farm Site in Gilchrist County, Florida, ~20.6—16.3 Ma.[2]
Description
editFloridaceras was of unusually large size for a rhinoceros of the Hemingfordian. It would have been roughly comparable to a black rhinoceros[3] in size, much larger than contemporaries such as the Menoceras. Like many primitive Aceratheriines, it has no horn, relatively long limbs and brachydont dentition (indicating it was a browser).[4]
