Also known as Peace River Area - Peace River Formation - Cadotte Member - Section 7 - Sample #7-C-3

Where: Alberta, Canada (56.7° N, 117.2° W: paleocoordinates 57.2° N, 65.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cadotte Member (Peace River Formation), Middle Albian to Middle Albian (109.0 - 99.6 Ma)

• This sample is in the Gastroplites Ammonite Zone.

• bed-level stratigraphic resolution

Environment/lithology: siltstone

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.
