Geography
Country: Mongolia
Coordinate: 45.15° N, 101.47° E
Coordinate basis: estimated from map
Time interval: Late Miocene
Zone: MN9
Geography comments: "in the Taatsiin Tsagaan Nuur Basin" (coordinate based on Taatsiin Tsagaan Nuur, which is a lake)
from layers 12 and 14 in the local section
"we correlate the Builstyn Khudag fauna with the early late Miocene, specifically with the early part of the Asian Bahean LMS/A and with the European Mammal Zone MN9 of the early Vallesian"

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: overbank deposit
Habitat comments: layer 12 is "3 m red to orange fine clayey silt with clay clasts and small vertebrate fossils embedded in the uppermost 10 cm thick layer" and layer 14 is "about 10 cm fossil rich silty orange clay" and these represent "floodplain deposits" and not channels
Methods
Life forms: rodents,other small mammals,snakes,lizards
Sampling methods: screenwash
Sample size: 897 specimens
Years: 1993, 1995, 1996
Museum: NHMW, Vienna
Sampling comments: "scattered vertebrate fossils were found... in 1993. Later, in the course of two field campaigns of the Mongolian-Austrian joint project (FWF-project: P-10505-GEO) a rich fossil collection was excavated in the summers of 1995 and 1996"
"The total amount was ca. 5000 kg sediment... The fossils are housed in the NHMW collection in Vienna, and in the MPC-col- lection in Ulaanbaatar" but only the NHMW fossils are detailed
"scattered bones of rhinos and proboscideans were collected" from "the flat area close to the base" of the section and "A mandible of a rhino was found in the upper part of the upper sandstone"
