The Menefee Formation consists of fluvial sandstone, shale, and coal.Based on ammonite biostratigraphy, the age of the Menefee Formation can be constrained to 84.2-79 million years (), based on the presence of Baculites perplexus in the overlying Cliff House Sandstone, and ammonites from the late Santonian in the underlying Point Lookout Sandstone.
