Collection methods and comments
| Reason for describing collection: | paleoecologic analysis |
| Taxonomic list comments:appears complete, with molluscs, barnacles, echinoids, and ostracods noted.
Unlike other collections in maunscript, forams not noted. Abundance counts determined as follows: whole gastropod shells and fragments with the top of the spire preserved were counted as individuals; valves (left or right) and umbonal fragments were counted and their number divided by 2. parietal plates of barnacles were counted and their number divided by 6 when dealing with Balanus and 4 when dealing with Verruca | |
