Judith River Group
The Judith River Group is a group of geologic formations in western North America dating from the late Cretaceous and noted as a site for the extensive excavation of dinosaur fossils.[citation needed] The formation is named after the Judith River in Montana. The group is also called the Judith River Wedge. It is stratigraphically equivalent with the Belly River Group in Alberta.[citation needed]
It comprises the Judith River Formation in north central Montana, as well as the Foremost, Oldman, and Dinosaur Park formations in Alberta and Saskatchewan in Canada.[citation needed] Within Canada, the name term Belly River Group is more widely used for what is essentially the same stratigraphic interval as the Judith River.[citation needed] The wedge is exposed discontinuously in river drainages.
