What anatomical evidence conclusively ties Paraceratherium to the rhino lineage?

Answer

Dental patterns and jaw structure

The definitive link between Paraceratherium and the rhinoceros family rests upon fundamental, internal anatomical structures, particularly the dental patterns and the overall structure of the jaw. Paleontologists rely on these deep homologies when classifying extinct megafauna, rather than focusing on potentially misleading external features like horns. The way the molars are shaped and aligned, along with the mechanics of the jaw articulation, aligns precisely with the expected blueprint for fossil rhinos. This shared anatomy distinguishes Paraceratherium from superficially similar large, hornless mammals like the uintatheres, whose jaw and tooth morphology would differ significantly.
