Sumatran rhinoceros
All three Asian rhinoceros once lived in China. Most depictions of rhinoceroses in Shang, Zhou and Han art show two distinct horns, and in some cases wrinkles around the eyes are also evident, which are features only found in the Sumatran Rhinoceros (Indian and Javan rhinoceroses only having a single horn). However, a few examples of sculptures showing one-horned rhinoceroses are also known, for example on a bronze cylinder supported by three rhinoceroses from the tomb of King Cuo of Zhongshan (late 4th century BC). Some historians have taken this as evidence that, in addition to the Sumatran Rhinoceros and Northern Sumatran rhinoceros which were more widely distributed within China, the one-horned Javan Rhinoceros was also present in ancient China. On the other hand, the posterior horn of the Sumatran Rhinoceros is often undeveloped and inconspicuous, so it is still possible that such examples of one-horned rhinoceroses may in fact also represent the Sumatran Rhinoceros.
