Paraceratheriidae

Paraceratherium is an extinct genus of hornless rhinocerotoids belonging to the family Paraceratheriidae. It is one of the largest terrestrial mammals that has ever existed and lived from the Early to Late Oligocene epoch (34–23 million years ago). The first fossils were discovered in what is now Pakistan, and remains have been found across Eurasia between China and the Balkans. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species P. bugtiense was originally placed.

Paraceratheriidae is an extinct family of long-limbed, hornless rhinocerotoids, native to Asia and Eastern Europe that originated in the Eocene epoch and lived until the beginning of the Miocene. They represent some of the largest terrestrial mammals to have ever lived.

Urtinotherium (meaning "Urtyn beast" in Ancient Greek) is an extinct genus of paracerathere mammals. It was a large animal that was closely related to Paraceratherium, and found in rocks dating from the Late Eocene to Early Oligocene period. The remains were first discovered in the Urtyn Obo region (now Dorbod Banner, Ulanqab) in Inner Mongolia, which the name Urtinotherium is based upon. Other referred specimens are from northern China.

Juxia ('joo-she-a'; from ) is an extinct genus of paraceratheriid, a group of herbivorous mammals that are related to the modern rhinoceros, that lived in Asia during the upper Eocene. The type species is J. sharamurenensis, named by Zhou Mingzhen and in 1964. thumb|left|Skull and neck of a mounted specimen of Juxia sharamurenensis, Paleozoological Museum of China As an early paraceratheriid, Juxia was a relatively small animal, around the size of a horse, compared to its later relatives, with a body mass estimated at or , held by elongated long legs and small skull firmly attached to a rela
