This article contains a list of fossil-bearing stratigraphic units in the state of Wyoming, U.S.
Viverravidae is an extinct monophyletic family of mammals from extinct superfamily Viverravoidea within the clade Carnivoramorpha, that lived from the early Palaeocene to the late Eocene in North America, Europe and Asia. They were once thought to be the earliest carnivorans and ancestral to extant ones, but now are placed outside the order Carnivora based on cranial morphology as relatives to extant carnivorans.
The Belle Fourche Formation or Belle Fourche Shale is a fossiliferous early Late-Cretaceous geologic formation classification in Wyoming. Named for outcrops in Belle Fourche River, Wyoming, this unit name is also used in Montana, North Dakota, and South Dakota.
The Gros Ventre Formation is a geologic formation in Wyoming, USA. It preserves fossils dating back to the Cambrian period. The Gros Ventre consists of three main members; the Wolsey Shale, the Death Canyon Limestone, and the Park Shale.
