Also known as Tanke Site 5

Where: Alberta, Canada (55.1° N, 119.5° W: paleocoordinates 64.0° N, 84.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wapiti Formation, Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; coal and gray, carbonaceous mudstone

• "The Red Willow Coal Zone is believed to represent deposition on a low gradient alluvial plain under high-accommodation conditions associated with reduction in sediment supply, high freshwater table, and abundant vegetation>"

• "The Red Willow coals are up to 1.5 m thick, extend laterally for a maximum of 5 km, and are commonly interbedded with dark gray, carbonaceous mudstone."

Size classes: macrofossils, mesofossils

Preservation: soft parts
