Geography
Country: Vietnam

State: Hoa Binh


Coordinate: 20° 37' 12" N, 105° 16' 25" E
Coordinate basis: stated in text

Time interval: Late Pleistocene

Min Ma: 0.066

Age basis: U/Th

Geography comments: "in Man Duc village" in Tan Lac District, Hoa Binh Province
there is one uranium series date of 66 +/- 3 ka on "flowstone, covering the level from which the teeth were recovered" that is stratigraphically a minimum

Environment
Lithology: breccia

Taphonomic context: cave,rodent accumulation

Habitat comments: "an argillaceous silty-clay at the base and a pisolite-rich fossiliferous muddy calcareous breccia above"
"almost all the finds... are isolated teeth with characteristic wear facets and gnawed roots indicating porcupine activity" but "water was the major taphonomic agent responsible for the transport and deposition of the teeth" and "No arguments show that humans might have a possible role in the taphonomic process"

Methods
Life forms: carnivores,primates,rodents,ungulates
