Gorman Creek Formation

The Gorman Creek Formation is an Early Cretaceous unit of the Western Canada Sedimentary Basin, dating to the Valanginian and exposed from northeastern British Columbia into west-central Alberta. Made chiefly of nonmarine sandstone, siltstone, mudstone, coal, and some conglomeratic beds, it preserves evidence of deltas, coastal plains, floodplains, and swamps along the margin of the Western Interior Seaway. It is especially significant for fossils, including plant remains, palynomorphs, other microfossils, and dinosaur trackways near the Narraway River, where more than 200 footprints in at least eight trackways include many from small theropods and one from a much larger biped.
