Nestoritherium is an extinct genus of chalicothere; it has been dated to have lived from the late Miocene to the Early Pleistocene (11.6–0.781 mya).[2][3][4] This range makes Nestoritherium one of the most recently dated chalicotheres. It has been found in fossil sites in Myanmar and China.[4]

The genus Nestoritherium was erected by German paleontologist Johann Jakob Kaup in 1859 for the species then known as Chalicotherium sivalense,[5] itself named in 1843 by Falconer and Cautley from early Pleistocene material from India.[6] The shortened faced and brachyodont dentition suggests it belongs to the subfamily Chalicotheriinae.[1]
Nestoritherium fuguense was named from partial lower jaw and palate material from Miocene beds in Fugu County, China in 2014.[6]
Material consisting of a fragmentary upper and lower molar recovered from the (early Pleistocene) Irrawaddy Formation in Myanmar has been referred to the genus Nestoritherium.[7] A femur of possible chalicothere origin was recovered from Pliocene deposits in Yenangyaung in 1897.[8]
