Abstract

The Beartooth Butte Formation is found in many mountain ranges throughout central Montana and northern Wyoming. This study combines a variety of geologic data to provide a clearer understanding of the fossil fauna and environmental setting of this rock unit. Results show not all exposures of this unit are fossil-bearing and where present, faunal data vary significantly from locality to locality. Also, not all exposures of the Beartooth Butte Formation are the same age. Lastly, isotopic data show a consistent pattern of ancient salinity for this rock unit through time, suggesting a constant environmental setting for approximately 20 million years.
