Also known as Russian-Mongolian Palaeontological Expedition, Khermeen Tsav

Where: Omnogovi, Mongolia (43.5° N, 109.1° E: paleocoordinates 42.2° N, 98.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Barun Goyot Formation, Late/Upper Campanian (83.5 - 70.6 Ma)

• Middle layers of the section on the northern slope in the Khermeen Tsav

• bed-level stratigraphic resolution

Environment/lithology: eolian; sandstone and red, white, carbonaceous conglomerate

• "perhaps eolian in origin"
• "Near the top of a sandstone unit about 15-20 m below a unit containing the carbonate concretions on a steep slope"

Size classes: macrofossils, mesofossils

Collected by RMPE in 1991

Collection methods: surface (float), surface (in situ), mechanical, sieve,

• 40 fragments are unidentifiable. Eggshell fragments found associated with the avian bones.
