Also known as Milk River
Where: Alberta, Canada (49.1° N, 110.7° W: paleocoordinates 56.3° N, 76.3° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Oldman Formation (Belly River Group), Late/Upper Campanian (83.5 - 70.6 Ma)
• in the upper member of the formation, ca. 25 m above the top of the Comrey Sandstone
• bed-level stratigraphic resolution
Environment/lithology: fluvial; green mudstone and paleosol/pedogenic, gray, sandy siltstone
•"The hadrosaur tracks occur at the surface of a thick, drab mudstone and are hosted within a light gray siltstone."
•"Strata exposed in the study area consist of interbedded mudstones, siltstones, and cross-stratified to laminated sandstones."
•"The tracks are exposed atop a drab green, structureless mudstone unit; however, their host sediment is a thin, light gray, sandy siltstone layer that immediately overlies this mudstone."
Size class: macrofossils
Preservation: cast, mold/impression, trace, concretion
