This listing offers a well-preserved upper molar of Stephanorhinus kirchbergensis (Merck’s rhinoceros), a Pleistocene rhinoceros species significantly rarer in the fossil record than the contemporaneous Coelodonta antiquitatis (Woolly Rhinoceros). Specimens of S. kirchbergensis are typically associated with the Eemian interglacial, and this tooth originates from Pleistocene deposits along the Amur River. The fossil exhibits a clearly defined occlusal wear pattern and a well-preserved linefeed (lamellar) enamel structure, both characteristic diagnostic features of the species. These attributes enhance its suitability for morphological comparison, taxonomic reference, and paleoecological study. Overall, this is a scientifically valuable and comparatively uncommon specimen, appropriate for research collections, institutional reference series, or advanced private collections.
