The Horsethief Sandstone is a Mesozoic geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[1] The southern part of the Two Medicine Formation grades into brackish water siltstone/sandstone series composing Horsethief Formation.[2] The sediments of the Horsethief represent shallower water deposits than the Bearpaw Shale adding further evidence of higher elevation areas existing to the south of the Two Medicine Formation's paleoenvironment.[2]
