The authors of the study found butchery marks on the bones of the ribs, metacarpals and both humeri suggesting that the rhino had been butchered by early humans or hominins.

A few years later, Ichiro Hayasaka of Taihoku Imperial University also rediscovered a more complete mandible near the site of Sato's specimen.

In December 1971, a team was formed by Taiwan Provincial Museum, including Prof. Chao-Chi Lin, Chang-Wu Pan, and Chun-Mu Chen (a well-known fossil collector from Zuojhen) to conduct the first excavation in Zuojhen to excavate rhinoceros fossils including teeth and limb bones, but some limb bones were still preserved in the original stratum.

[1] Both species are relatively small, and comparable in size to living Sumatran and Javan rhinoceros, with shoulder heights of 123–131 centimetres (4.04–4.30 ft), with Nesorhinus hayasaki being somewhat larger than N. philippinensis with an estimated body mass of approximately 1,018–1,670 kilograms (2,244–3,682 lb), in comparison to 998–1,185 kilograms (2,200–2,612 lb) estimated for N.

[10] The fossils from the Chiting Formation suggest that the habitat of the Nesorhinus hayasakai was probably an open grassland, and the animals in the ecosystem are collectively known as the Chochen fauna, which includes large animals such as mammoths, Elaphurus, wild boars, Rhinopithecus, Homotherium, Toyotamaphimeia that cohabitated with the Nesorhinus hayasakai.
