The subject of this week’s Fossil Friday is a rhinocerotid (commonly known as rhinos) that has been found in Florida and Panama called Floridaceras whitei. Rhinocerotids (Family Rhinocerotidae) belong to the order Perissodactyla, the odd-toed ungulates. This specimen of Floridaceras whitei is from the Hemingfordian Thomas Farm locality in Florida, however it is also known from the Gaillard Cut Local Fauna (Cucaracha Formation) of Panama of similar age. This specimen consists of a right dentary with the lower deciduous second through fourth premolars (dp2-dp4), showing that this dentary belonged to a juvenile F. whitei.
