W2 tracksite (Cretaceous of Canada)

Also known as Smoky River Coal Mine

Where: Alberta, Canada (54.0° N, 119.3° W: paleocoordinates 55.2° N, 68.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Grande Cache Member (Gates Formation), Albian (113.0 - 100.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; bioturbated, fine-grained sandstone

• "Primarily laminated fine sands with a moderate amount of organic material. There is evidence of some water currents (cross-bedding) and multiple influxes of sediment (high energy). May have been close to a river tat flooded the area periodically."

Size class: macrofossils

Preservation: mold/impression, trace

Reposited in the TMP

Collection methods: surface (in situ),
