Pinhorn Range #93-2, RTMP L1133 (Cretaceous of Canada)

Also known as PHR 93-2

Where: Alberta, Canada (49.1° N, 110.8° W: paleocoordinates 56.4° N, 76.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Lower Member (Oldman Formation), Middle Campanian (83.5 - 70.6 Ma)

• lower unit of formation; 24.5 m above top of Taber Coal Zone

• bed-level stratigraphic resolution

Environment/lithology: "channel"; lenticular sandstone and fine-grained sandstone

• "The host lithosome is a 1.25 m-thick, fining-upward sandstone body, composed of 75 cm of large-scale trough cross-beds that then pass into heterolithic incliined units. The heterolithic beds comprise fine-grained sandstone with abundant plant debris. Vertebrate microfossil remains occur in the transition from the cross-bedding to the heterolithic inclined beds."

Size class: mesofossils

Reposited in the TMP

Collection methods: bulk, sieve,
