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. 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.
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. Within Canada, the name term Belly River Group is more widely used for what is essentially the same stratigraphic interval as the Judith River. The wedge is exposed discontinuously in river drainages.

“In order to get to East Russet you take the Vermont Central as far as Twitchell’s Falls and change there for Torpid River Junction, where a spur line takes you right into Gormley. At Gormley you are met by a buckboard which takes you back to Torpid River Junction again.”
—Robert Benchley (1889–1945)
“The conflict between the need to belong to a group and the need to be seen as unique and individual is the dominant struggle of adolescence.”
