Lithology description: "Sandstone is grayish orange to yellowish brown, fine- to medium-grained, subangular to rounded and moderately well sorted quartzarenite. Lower 20 cm has sinuous- and straight-crested ripples, low angle trough crossbeds, horizontal laminae and tool marks. The upper 10 cm is intensely bioturbated by both dinosaur footprints and numberous small, smooth-walled horizontal tubes. The sandstone overlies 2.1 m of light brownish gray silty shale."
