Fossilized Sumatran rhino skull found in Guizhou

Chinese scientists recently found a fossilized skull of a Sumatran rhino, a critically endangered species, in Asia's longest cave in the southwestern province of Guizhou.

The discovery may enrich understanding of the region's ecology in ancient times and provide insights into the animal's extinction in China.

The fossil was unearthed by a team of researchers from the Guizhou Institute of Mountain Resources in an upper passage of the Shuanghe Cave in Zunyi. The entire cave system is more than 409 kilometers long and as deep as 912 meters.
