Bear Gulch Fossils

The Bear Gulch Limestone of Montana is a lagerstätte, a well-bedded sequence of limestone layers containing an extremely well-preserved assemblage of fossils. This deposit has yielded one of the most diverse and well preserved fossil fish assemblages in the world. The site also contains well preserved arthropods, sponges, starfish, conulariids, worms, and other soft-bodied organisms, as well as brachiopods, bryozoans, and molluscs. The Bear Gulch fossils are so well preserved that they provide a window into the life of the Mississippian that has never been available before
