Lithology and environment
Primary lithology: cherty/siliceous "limestone"
Lithology description: ... a gray limestone, 11 ft thick, containing numerous chert nodules. These nodules and the limestone commonly contain specimens of Millerella marblensis, Fusiella, various textulariid genera, a linguloid brachiopod, hexactinellid sponge spicules, and crinoid fragments in addition to the dominant gastropods. The matrix consists of well-sorted invertebrate fragments about the same size as the majority of the gastropods, along with scattered glass sponge spicules.
Environment:offshore shelf
Geology comments: This suggests an off-shore environment. However, Lane (1981: 200-201) cited evidence of several Pennsylvanian faunas such as those in the Perth Limestone of Indiana where spiculites are associated with coal cyclothems indicating
shallower water. However, in much of the Paleozoic, spiculites are suggested to represent off-shore, deepwater niches.
