Pinhorn Range #1, RTMP L1125 (Cretaceous of Canada)

Where: Alberta, Canada (49.1° N, 110.9° W: paleocoordinates 56.4° N, 76.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Foremost Formation (Belly River Group), Middle Campanian (83.5 - 70.6 Ma)

• upper unit of formation (base of third unit), 25 m below Oldman Fm

• bed-level stratigraphic resolution

Environment/lithology: shoreface; fine-grained, pebbly, carbonaceous sandstone and mudstone

• "it is interpreted as a regressive surface of erosion that is related to a drop in relative sea-level."
• "massive (about 3.5 m thick), fine-grained sandstone body, which rests sharply on the underlying dark marine shales of the fourth parasequence of the middle (mudstone) succession. THe overlying sandstone body comprises low-angled to planar sets of ripple-laminated sandstone, with a massive and pebbly base that is traceable about 10 m laterally."

Size classes: macrofossils, mesofossils

Reposited in the TMP

Collection methods: bulk, sieve,
