Also known as Peace River Area - Loon River Formation - Section 8 - Sample #8-L-11

Where: Alberta, Canada (57.1° N, 117.2° W: paleocoordinates 57.6° N, 65.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Loon River Formation, Middle Albian to Middle Albian (109.0 - 99.6 Ma)

• This sample is in either the Verneuilina porta or Marginulinopsis collinsi Foraminifera Zone. It is also in the Beudanticeras and Subarcthoplites Ammonite Zone.

• bed-level stratigraphic resolution

Environment/lithology: marine; shale

Size class: microfossils

Preservation: original sporopollenin

Collection methods: surface (in situ), chemical, sieve,

• Singh states that samples were sieved with a 100um seive, but that the residue in the sieve was scanned for identifiable specimens, thus no sieve size is entered.
