in 1859 for the species then known as ''Chalicotherium sivalense'', itself named in 1843 by Falconer and Cautley from early Pleistocene material from India. The shortened faced and brachyodont dentition suggests it belongs to the subfamily Chalicotheriinae. ''Nestoritherium fuguense'' was named from partial lower jaw and palate material from Miocene beds in Fugu County, China in 2014. 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''. A femur of possible chalicothere origin was recovered from Pliocene deposits in Yenangyaung in 1897.
