About This Object

Geologic period: Cenozoic — specimen chronology flagged for review

Age: Smithsonian's current catalog record labels this specimen Miocene. Broader Paraceratherium literature is commonly associated with Oligocene deposits, so SAGE retains the catalog record but flags the age for specimen-level review.

Feeding: Herbivorous.

Evidence: The skull provides direct evidence for cranial anatomy. Body size and posture are reconstructed using associated skeletons and related specimens.

Why it matters: Paraceratherium demonstrates the extreme body sizes achieved by hornless rhinocerotoids during the Cenozoic.

Plain Language Identity: A gigantic hornless rhinocerotoid and one of the largest terrestrial mammals known.

What You Are Looking At: A cast representing the enormous skull of Paraceratherium transouralicum.

Ecosystem: Asian Cenozoic terrestrial ecosystem.

Provenance Note: The Smithsonian catalog currently combines a Miocene age field, Hsanda Gol Formation terminology and a Pakistan locality. SAGE preserves those source fields but does not silently reconcile the apparent chronology/provenance conflict.

Open Questions: Specimen-level age and formation require additional catalog verification before a narrow numeric date is published.

Enrichment Method: SAGE curated research pass; title + scientific name + source scene matched; chronology and taxonomy conflicts retained rather than silently corrected; evidence separated from inference
