Milk River #9 (GSC 3934) (Cretaceous of Canada)

Where: Alberta, Canada (49.1° N, 113.5° W: paleocoordinates 50.4° N, 71.0° W)

• coordinate based on nearby landmark

When: Milk River Formation, Early/Lower Cenomanian (99.6 - 93.5 Ma)

• formation-level stratigraphic resolution

Environment/lithology: terrestrial

• In outcrop the Milk River Formation comprises three members: the Telegraph Creek, Virgelle, and Deadhorse Coulee (lower Eagle Formation equivalent). These members form a regressive succession from offshore marine to non marine coastal plain deposits.


• "The strata consist generally of alternating series of sandstones and shales with all gradients between the two....contains clay ironstone concretions, large plant stems and tree trunk imprints and casts, ripple markings, worm borings... carbonaceous fragments and coal seams..."

Size class: macrofossils

Preservation: mold/impression, adpression, original carbon

Reposited in the GSC

Collection methods: bulk,
