WebThe Perissodactyla contains only seventeen living species, classified into three living sub-groups: the horses, the rhinoceroses, and the tapirs. In the early Cenozoic , perissodactyls were much more diverse, including the great extinct brontotheres and Indricotherium , the largest land mammal of all time. WebThere are two main subgroups, or suborders under the order of Perissodactyla. These two suborders are Hippomorpha and Ceratomorpha. Perissodactyls who fit into the suborder of Hippomorpha are, today, fast runners with long legs and one toe per foot. The only extant family of this suborder is Equidae, whose sole surviving genus is Equus.

WebThe most recognizable, defining external structure that defines an organism as a member of the order of Perissodactyla is the trait of having either one or three toes on their hind legs. In addition to this, all Perissodactyla share the traits of … WebThis order has remained abundant and diverse since that time (18 extinct families of ungulate artiodactyls are known in addition to the ten modern families), while the formerly highly successful Perissodactyla have continually declined. The highly specialized cetaceans are believed to have evolved from the Archaeoceti, a group of primitive ... WebPerissodactyls are characterised chiefly by: mesaxonic feet (line of symmetry down third digit); a full set of incisors; greatly molarised pre-molars. They were once a very widespread and diverse group, but have been on the wane since the late Miocene as the artiodactyls have prospered. SUBORDER CERATOMORPHA. check river island gift card
