Hualongdong 6 (HLD-6)

3D Model

This model was obtained by applying advanced photogrammetry technologies and cutting edge techniques currently not applied to this field that have allowed me to recreate previously unattainable models like Harbin, Yunxian 2 and now HLD-6. This model represents a reconstruction of the HLD-6 cranium from the Hualongdong paleoanthropological site in Dongzhi County, Anhui Province, China.

The HLD-6 individual lived during the late Middle Pleistocene, approximately 300,000 years ago. Stratigraphic and geochronological studies place the Hualongdong hominin assemblage between roughly 331–275 thousand years ago.

This digital reconstruction was created using published anatomical descriptions and visual references from the study “Craniofacial reconstruction and morphological analysis of the HLD-6 skull” (Acta Anthropologica Sinica, 2025) and scaled using cranial measurements from the supplementary dataset of “The phylogenetic position of the Yunxian cranium elucidates the origin of Homo longi and the Denisovans.”
