Scollard Formation
Upper Cretaceous to lower Palaeocene stratigraphic unit of the Western Canada Sedimentary Basin / From Wikipedia, the free encyclopedia
The Scollard Formation is an Upper Cretaceous to lower Palaeocene stratigraphic unit of the Western Canada Sedimentary Basin in southwestern Alberta.[1][3] Its deposition spanned the time interval from latest Cretaceous to early Paleocene, and it includes sediments that were deposited before, during, and after the Cretaceous-Paleogene (K-Pg) extinction event. It is significant for its fossil record, and it includes the economically important coal deposits of the Ardley coal zone.
