Price Creek tracksite 1 (PCr1) (Cretaceous of the United States)

Also known as Western Centennial Mountains, WCM

Where: Beaverhead County, Montana (44.6° N, 112.1° W: paleocoordinates 49.0° N, 75.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Frontier Formation, Coniacian (89.8 - 86.3 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: alluvial fan; lithified, fine-grained sandstone and siltstone

• "Conglomerates are rare at the WCM and URR localities where the successions are dominated by fine-to-medium grained, cross-bedded sandstones, ripple-laminated siltstones, and mudstones. Medium-to-coarse grained, trough-crossed bedded and ripple-laminated sandstones form relatively thin and extensive channel bodies isolated by thick sets of fine-grained, overbank lithofacies"

•"The track-bearing horizon herein described consists of a 20 cm thick, fine-grained, cross-bedded sandstone, extending laterally about 15 m."

Size class: macrofossils

Preservation: cast, trace
