Primary lithology:lenticular,current ripples,coarse,very coarse,white,yellow lithified sandstone
Secondary lithology:planar lamination claystone
Includes fossils?Y
Includes fossils?Y
Lithology description: "the bones are for the most part found in a very hard layer of sandstone, though they occasionally extend down for a short distance into the underlying clays." Sandstone described as "heavily bedded". Bones in a "coarse to gravelly, pale yellowish white sandstone." Sandstone body is broadly lenticular.
Environment:"channel"
Geology comments: "river, lake, or estuary origin rather than consolidated beach sands"; "lower lacustrine unit, dominated by laminated mudstones and shales"; channel top-point bar in moderately drained floodplain. Most bones in upper channel lag, rather than lower point bar.
