Lithology and environment
| Primary lithology: | ferruginous sandstone |
| Secondary lithology: | siltstone |
| Includes fossils? | Y |
| Lithology description: Formation as a whole: "alternation of sandstones, siltstones, and shales". This sample: "fossils occur in a ferruginous sandstone and are evidently replaced" | |
| Environment: | marine indet. |
| Geology comments: random shell orientation; fragmentation; disarticulation; dominance by coarsely costate rhynchonellids, weakly concavo-convex productids, and some inarticulates; interpreted as shallow marine, near coast, BA2. | |
