Belly River Group

The Belly River Group is composed of very fine grained sandstone with coarse grained beds and minor bentonite, coal, green shale, and concretionary beds. Hydrocarbon production Gas is produced from the Belly River Group in the Deep Basin, in west-central Alberta and in the Canadian Rockies foothills. ==Paleofauna==

Dinosaur remains are among the fossils that have been recovered from the formation. ==Distribution==

The Belly River Group reaches a maximum thickness of in its western reaches, and thins out eastward to about in the Canadian Plains. It is found throughout southern Alberta, and as far east as eastern Saskatchewan. From south to north, it is present from the United States border to the Wapiti River region, south of the Peace River Country. ==Relationship to other units==

The Belly River Group is conformably overlain by the Bearpaw Formation and gradually overlies the Wapiabi Formation, the Colorado Group shale or the Lea Park Formation shale. It is equivalent to the Milk River Formation and Pakowki Formation. The Belly River has group status in the Canadian Rockies foothills and is replaced by the Oldman Formation (Judith River Formation in Montana) and Foremost Formation in southern Alberta. ==See also==
