Secondary lithology: | marl |
Includes fossils? | Y |
Lithology description: "Occurs chiefly as articulated specimens in several thin interbeds, 5-15 cm thick, of dark gray, commonly argillaceous limestone, interbedded with thin marl, argillaceous shale, and dark brown, fine-grained sandstones and thicker dark gray limestones containing Atrypoidea prunum gigas Community." | |
Environment: | marine indet. |
Geology comments: "Interbedding of communities suggests similar BA position...Community interpreted as quiet water, soft, level bottom unit near BA 2-3 boundary in agreement with associated fossils." |
