Lartetotherium is an extinct genus of rhinocerotid that lived during the Miocene in Europe and possibly China.Deng, T.; Li, S., 2023. Restudy of Rhinocerotini fossils from the Miocene Jiulongkou fauna of China. Vertebrata PalAsiatica 61: 198-211 - DOI: 10.19615/j.cnki.2096-9899.230630
The type species Lartetotherium sansaniense was a unique cursorial rhinoceros with a distinctly long horn. Its teeth were brachyodont, indicating its diet contained a high quantity of soft plants and a lower proportion of woody material.
A 2023 study reassigned the species Dicerorhinus cixianensis (Chen and Wu, 1976) from the Middle Miocene of Cixian County, Hebei Province, China, to the genus. The species is known from a single partial skull and juvenile mandible, notably small in size.
Palaeoecology Analysis of δ18O and δ13C values suggests that L. sansaniense was an inhabitant of relatively open environments.
