On August 22, 2011, the Anhui provincial government reorganized the province and split Chaohu into three parts that were absorbed by neighboring prefecture-level cities.

The human remains discovered at Hexian includes a vault, cranial fragments, mandibular, and dental elements catalogued as PA830-PA835 and PA840-PA845.

The site containing hominin material was excavated in 1980 and May through June 1981 by IVPP teams alongside many other transitional mammalian fossils in layer 4 of Longtan Cave.

[8] It was once called Homo erectus hexianensis,[9] but other studies suggest that the differences in the specimen are not differentiating on the subspecies-level.

[6] The thickness, profile, brow, and distinct nuchal-occipital boundary are alike Chinese Homo erectus.

However, a lack of postorbital constriction, increased width, a curved sagittal profile, a long parietal, and a high temporal are unlike these groups.

The mandibular body was robust, and a well-differentiated mylohyoid line and a posteriorly-positioned lateral prominence are derived traits.
