FOSSILS SPECIMEN: PERISSODACTYLA

Fossils are defined as any evidence of prehistoric life. There are two types of fossils: Body Fossils include remains of skeletal bones, shell, carapace, test and teeth. Trace Fossils are clues the organism existed such as foot prints, tracks, burrows and coprolites (fossil dung).

Perissodactyla meaning “odd fingers”, are more commonly called Odd-toed ungulates; are a taxonomic order of mammals that bear their weight on one of five toes, usually the third (or middle) toe. The modern representatives of this group are horse, tapirs and rhinoceros, but they have a greater diversity in the fossil record than today. To see my Perissodactyl models click here.
