Near-horned beast
Indricotherium, also known as Paraceratherium, represents an extinct genus of some of the largest land mammals to have ever existed. These colossal animals could reach heights of 16 feet and lengths of 24 feet, weighing between 15 to 20 tons. Despite its classification debate, Indricotherium is recognized for its unique anatomical features, including a robust body supported by long, straight legs, reminiscent of modern elephants. Unlike today’s rhinoceroses, Indricotherium lacked a prominent horn but possessed short tusks formed by incisors, which it used for foraging high tree foliage and for defense. Its diet mainly consisted of leaves and plants, as its shorter neck limited its ability to graze on ground vegetation.
Fossil evidence indicates that Indricotherium inhabited forests and wooded plains across central Asia, Eastern Europe, and the Middle East. This solitary animal likely had a reproductive strategy similar to that of modern large mammals, with females giving birth to a single calf after a long gestation period. The sheer size of Indricotherium meant it faced minimal predation threats, allowing it to thrive in its environment until its eventual extinction.

Indricotherium
Paraceratherium, sometimes call the near-horned beast, is an extinct genus containing some of the largest land mammals that ever lived. Scientists continue to debate the classification of these animals. It was once classified as being in the genus Indricotherium, but this was changed to Paraceratherium. It could eat the leaves in trees as high as 25 feet (7 1/2 meters).
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Perissodactyla
Family: Paraceratheriidae
Genus: Paraceratherium
Species: Various (see below)
Four species existed in the paraceratherium genus. Scientists continue to debate this animal's classification. At a height of 16 feet (almost five meters), length of 24 feet (7 1/3 meters), and weight of 15 to 20 tons (between 13 and 18 metric tons), Paraceratherium was by far one of the largests land mammals to have roamed the earth. Because of its great weight, Paraceratherium could not bend its legs easily without hurting them. So, like elephants today, it kept its legs fairly straight when it walked. It had long feet with short elephant-like toes. Supporting its large, heavy head was a short, muscular neck. The mouth had a flexible upper lip and a row of tough teeth. Although it was from the rhinoceros family, Paraceratherium did not have a horn like the rhinoceros we see today. It had short tusks that were formed by a pair of upper and lower teeth called incisors. It used these teeth for eating and to defend itself when being attacked. The male Paraceratherium used its tusks to show its strength to other males.
Paraceratherium lived on a diet of plants, leaves, and vegetation. Because the animal's neck was shorter than its front legs, it could not reach down to eat the grass and low vegetation. It used it height to feed on the higher trees. The front legs of Paraceratherium were longer than its rear legs. This made it possible for it to reach even higher. The upper lip of this giant animal was rubbery and allowed it to nibble at the branches delicately. Fossils of Paraceratherium's cheek teeth showed it probably preferred foliage, or leaves, over grass because it was easier to grind up and digest.
Because of its large size, Paraceratherium had very few enemies.
Paraceratherium lived in the forests and on wooded plains. It was believed to have been a solitary animal, or one that chose to live alone.
Little is known about the breeding habits of Paraceratherium. They were probably similar to today's big land mammals like the elephant. The female was pregnant for up to two years. She gave birth to one calf, or baby mammal, at a time. The baby then depended on its mother for milk until it was old enough to be on its own.
Fossil remains of Paraceratherium have been found in central Asia. It is also believed to have lived in Eastern Europe and the Middle East. The species of Paraceratherium are extinct.
