| 背面描述 | The reverse presents a high-relief sculptural rendering of disarticulated fossil skeletal remains of a Nimravidae, an extinct family of sabre-toothed carnivorous mammals, displayed across the central field. The fossil elements, including the distinctive elongated upper canine teeth characteristic of the taxon, are depicted with palaeontological accuracy against a polished field. The legend 'Nimravidae' is inscribed in Latin script along the upper left arc, while '2023' appears at lower left and 'EVOLUTION' is inscribed in large Latin capitals along the lower rim. |

Nimravidae — often called "false saber-tooths" — were not true felids but occupied an almost identical ecological niche across North America and Eurasia from the Eocene through the Miocene, a case of convergent evolution that still generates taxonomic argument. Mongolia's numismatic program has leaned heavily into paleontological subjects since the early 2000s, reflecting the country's status as one of the world's most productive fossil-bearing territories — the Gobi Basin alone has yielded type specimens for dozens of Cretaceous and Cenozoic genera.
