An Oligocene giant rhino provides insights into Paraceratherium evolution

A 155-character analysis places the 26.5 Ma Paraceratherium linxiaense as a derived member of a monophyletic Oligocene Paraceratherium clade, with detailed within-genus relationships remaining analysis-dependent.

Paraceratherium is treated as an Oligocene paraceratheriid genus; the six sampled species form a monophyletic clade in the cited 155-character analysis.

The atlas displays the 26.5 Ma Paraceratherium linxiaense LX1808 occurrence as a point sample and does not treat it as a genus-wide first or last appearance.

P. linxiaense preserves a giant skull, mandible and cervical vertebrae consistent with a large body and long flexible neck; the study does not support elephant-like stubby graviportal limbs.

Paraceratherium is represented as a giant terrestrial herbivore associated in the cited study with Oligocene Asian woodland–grassland mosaics; high feeding reach is an anatomical inference, not observed behavior.

The cited phylogeny and occurrence map place Paraceratherium species across the Mongolian Plateau, northwestern China, Kazakhstan and Pakistan and infer dispersal through the Tibetan region.
