Stratigraphy
Stratigraphy comments: Monograptus perneri and bottom of Istrograptus transgrediens 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 each. Environment shallow, certainly below wave base, subtidal. Shells attached to each other or to the sea bottom." |
Taphonomy
Collection methods and comments
Reason for describing collection: | paleoecologic analysis |
Collection method comments: Despite distribution, text seems to imply that all faunal elements are found at type locality. |
