Where: Lang Son, Vietnam (22.0° N, 106.4° E: paleocoordinates 21.9° N, 106.4° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Middle Pleistocene (0.8 - 0.1 Ma)
• from "Two distinct breccia layers, a lower light red unit and an overlying darker red one... the darker one [contains] most of the fossil vertebrate remains... there is no sharp discontinuity between the layers, which were deposited during the same period... faunal analyses... suggest a late middle Pleistocene age (probably around 300-250 Ka) for the entire contained mammalian assemblage"
• group of beds-level stratigraphic resolution
Environment/lithology: cave; lithified, shelly/skeletal, red breccia
Size class: macrofossils
Collected by T. K. Le, V. B. Tran in 1965, 1966
Collection methods: bulk, quarrying, mechanical,
• collected by "a joint Vietnamese and German (DDR) group... Blocks... were removed... using hammers and chisels, following which manual preparation of the specimens was completed in the laboratories of the Institute of Archaeology in Hanoi"
