Stratigraphy
| Formation: | Foremost | Member: | Blood River Sandstone | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Blood River Sandstone, which overlies gradationally the Late Campanian Bearpaw Shale, and is presumably overlain by the Eastman Fm (Early Maastrichtian). AGE: Late Campanian on the basis of ammonite (and other groups) biostratigraphy; Baculites compressus zone. Late Campanian according to Dawson et el. - Geological Atlas of the Western Canada Sedimentary Basin. STRATIGRAPHIC POSITION: From unknown position within the Foremost Fm. | |||||
