Big lips rhinoceros (chilotherium) is a very prosperous country on a Pliocene animals. It belongs to the class Perissodactyla angle suborder (ceratomorpha) in the General Division rhinoceros (rhinocerotoidea).
Big lips rhinoceros stocky body, short limbs. Both before and after the three-toed feet. Skull short, nasal bone length and weak, no angle. Lower jaw with the Ministry of stout and expanded into a shovel-shaped. Incisors large, wide spacing, extending out the top. Smaller than the premolars and molars move forward rapidly after decreasing. The first molars with thick thorns and anti-stab before. Significantly larger second molar.

Within the toe around the foot (ie, big toe) and fifth hind toe are degraded disappeared; the fifth toe in the forefoot to keep the original type, the type of progress has disappeared. Therefore, Perissodactyla often enough before and after the class work of only three toes, and in the progress of the modern horse class, leaving only one in the toe. Perissodactyla class ankle, talus proximal (ie closer to that end from the body) has a double pulley-shaped protruding surface, and distal tibia (ie, far away from that end of the body) the relevant section of the talus far connecting the ankle bones and the other end was flat at the surface. The work focused on a few toes until a toe on the talus with a pulley structure, these two points makes Perissodactyla class to run faster to escape a dangerous predator, which is Perissodactyla class beyond the ankle section with an important class progressive features. In addition, Perissodactyla class backbone of the femur in a significant lateral protrusions, called the third switch section. |
