Stratigraphy
Lithology and environment
| Primary lithology: | calcareous "shale" |
| Secondary lithology: | sandstone |
| Includes fossils? | Y |
| Lithology description: "This comm. occurs in thickly bedded shales. The lime content is very low, and there are some very thin fine-grained sandstone interlayers." | |
| Environment: | offshore indet. |
| Geology comments: "...signs of transport [valve ratios] within habitat...clearl shallowing trend throughout section... offshore environment and deposition immediately below storm wave base...A BA 5 assignment is likely..." | |

Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Table 22.5 gives absolute and relative abundances. This collection reflects the same material as collection number 13845, but species names and other taxa have been added. | |
| Taxonomic list comments:Some taxa not listed to genus level. | |
