Abstract
The oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation.
