Ungulates Educational Poster 24.5x36.5 - Laminated This poster is 24" x 36" with a .25" laminate border and makes the perfect addition to classrooms, studies, offices, and children's or student's bedrooms. The lamination protects it from tears, dirt, dust, and moisture for many years of enjoyment. Ungulates are hoofed animals. Most use the tips of their toes to sustain their entire body weight while moving. Under the Linnaeus classification system, all were originally classified into one order, Ungulata. It was later split into two orders: (1) the Perissodactyla, or odd-toed ungulates, which includes horses, tapirs, and rhinoceri totaling 15 living species; and (2) the Artiodactyla, or eventoed ungulates. It contains about 220 species that includes pigs, camels, hippopotamuses, chevrotains, deer, giraffes, sheep, goats, cattle, and America’s unique pronghorn antelope, the sole species in its family. There is controversy regarding classification. Some scientists maintain that ungulates are a cladistic (evolution-based) group. Others argue that they are a phenetic group or folk taxon (similar, but not necessarily related) because not all ungulates appear as closely related as once believed. Whatever the outcome of this dispute, it is fairly certain that regardless of whatever classification system eventually prevails, it will almost surely contain the same species. This poster is divided into two sections, one for each of the two orders. Within them, all of the families are explored.
