Stratigraphy
| Stratigraphy comments: Monograptus bouceki-M. perneri biozones. |
Lithology and environment
| Primary lithology: | calcareous mudstone |
| Lithology description: "Disarticulated adult and juvenile shells formed clumps on bedding planes of dark, calcareous mudstone." | |
| Environment: | marine indet. |
| Geology comments: "Very high density but low diversity population of one species only...Environment shallow, certainly below wave base, subtidal. Individuals attached to each other or to the sea bottom." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Despite distribution, text seems to imply that all faunal elements are found at type locality. | |
| Taxonomic list comments:Because of the vertical spread of these beds, it is not possible to tell with certainty from ref. 6630 which graptolites are present. | |
