| Stratigraphic resolution: | group of beds |
Lithology and environment
| Primary lithology: | glauconitic,gray,blue unlithified calcareous sandstone |
| Lithology description: Sand, dark-blueish-gray, massive, calcareous, glauconitic, fossiliferous. The upper beds contain abundant "Ostrea" thirsea but few other fossils. Bed 1, lower part, of Toulmin, LaMoreaux, and Lamphere, 1951, p. 61, contains a large number of species of beautifully preserved mollusks. The bed is now covered by the backwater from Coffeeville Dam. | |
| Environment: | shallow subtidal indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | mesofossils |
