Life restorations are artistic reconstructions based on fossil evidence; true coloration and soft-tissue details remain uncertain.
Coelodonta
Coelodonta antiquitatis (Coelodonta · ケブカサイ)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 A weight of about 2.9 tons is similar to the combined weight of about 2 passenger cars (about 1.5 tons each) (Comparison).
- 💡 The average weight of an adult's nasal horn, just over 6 kg, is slightly more than half of a 10 kg bag of rice (Comparison).
- 💡 A record-breaking horn measuring 164.7 cm in length was discovered in the permafrost of Sakha (Yakutia), Russia, and studied.
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.

📖 1. Overview
Coelodonta antiquitatis is a rhinoceros representing the mammoth–woolly rhinoceros fauna of northern Eurasia during the Late Pleistocene. Covered in thick, long hair, it was adapted to the cold.
🦴 2. Anatomy & Morphology
Its heavy body (about 2.9 tons), short legs, wide lips, low-slung head, long nasal horn, and high-crowned teeth were well suited for grazing grass. In adults, the nasal horn averaged over 1 m in length and weighed just over 6 kg on average.
🔍 3. Fossil Record & Paleoecology
Tooth wear patterns and plant remains indicate that it was a grazer that fed mainly on tough grasses. Some studies also suggest that it changed its diet with the seasons.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
