Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: "Hamada (1971) favored Early Emsian age..His discussion suggests that this is the most likely assignment based on known ranges of the genera he recognized. It is unlikely that the age will be outside the Late Siegenian-Emsian range." |
Lithology and environment
Primary lithology: | green argillaceous,calcareous sandstone |
Secondary lithology: | sandstone |
Includes fossils? | Y |
Lithology description: "Shells occur in a calcareous, argillaceous, medium- to fine-grained greenish sandstone, as largely disarticulated specimens." Hamada also mentiones white, massive, hard, medium-grained sandstone. | |
Environment: | marine indet. |
Geology comments: "Typical BA 3 community...The size of the faunal list as well as the relative rarity of some of the shells, suggests that a few of the rarer taxa may have become admixed by current transport...Assemblages of this type normally repreesent relatively normal, level-bottom conditions within the BA 3 region." |
Taphonomy
Collection methods and comments
Reason for describing collection: | paleoecologic analysis |
Collection method comments: "Many slabs of fossiliferous sandstone" (Hamada). Table 20 of ref. 7183 (which includes specimen counts for brachiopods), taken from table 5 of Hamada (ref. 7190). Table 20 actually lumps two of Hamada's lists. I have kept Hamada's lists separate and have added other taxa mentioned by Hamada. |
