Below this is a series of gray clays, siltstones and organic-rich clays, extending to a 6-foot lignite 50 feet below the base of the sandstone. This section continues in the Hell Creek Formation below the lignite to a total of 415 feet, but not to the contact with the underlying Fox Hills Sandstone. The megaspore samples are all from above the lignite, and are all in the Hell Creek Formation on the basis of an analysis of the pollen a | "shale" | 145 - 66 Ma Cretaceous |
