Barrett Wall 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)

• two track-bearing horizons

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; shale

• "There is a patchy, friable upper horizon composed of relatively fine-grained, organic sediments and an extensively exposed underlying horizon that is slightly shaly but more consolidated than the upper horizon."

Size class: macrofossils

Preservation: mold/impression, trace

Collected by McCrea, Currie, Pemberton in 2001; reposited in the TMP
