Gurilin Tsav tracksite [HMNS-GIN] (Cretaceous to of Mongolia)

Also known as Gurlin Tsav, Guriliin Tsav

Where: Omnogov, Mongolia (43.9° N, 100.1° E: paleocoordinates 41.0° N, 89.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Nemegt Formation, Late/Upper Campanian to Late/Upper Campanian (84.9 - 66.0 Ma)

• > 5 horizons with footprints

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; lithified, fine-grained, gray sandstone and mudstone

• "alternation of sandstone and mudstone layers. Thick sandstone layers are developed in the upper part of geologic section of this locality. Those layers might be partly of eolian origin. In the beds paleosol (calcareous concretions) are frequently developed. The paleocurrent direction observed in the trough-cross-stratification in sandstone layers shows south, southwest, and west. Strike of wave ripple mark on hard gray fine-grained sandstone layer with dinosaur footprints is 155 (or 335) degree."

Size class: macrofossils

Preservation: cast, trace
