Ptenophyllid Assemblage of the Pridolian in the Appalachian belt (Silurian of the United States)

Also known as Reef 1424

Where: Pennsylvania (41.0° N, 77.0° W: paleocoordinates 32.6° S, 40.2° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Jersey Shore Member (Keyser Limestone Formation), Pridoli (423.0 - 419.2 Ma)

• Assemblage is known from a range of formations in Pridolian through Lochkovian strata, but the understanding of Pridolian elements is based mainly on Jersey Shore member of Keyser Lst.

Environment/lithology: reef, buildup or bioherm; carbonate

• Stromatoporoid biostromes, interpreted as very shallow, subtidal, separating lagoonal area from somewhat deeper, more normal but still shallow shelf with moderately diverse shelly fauna. Rugosans occur intergrown with and in between the stromatoporoids that create the framework.

•SEP: environmental call sort of sketchy because of basin-scale analysis. however, these features should be common to the buildup portion of the Keyser Ls. everywhere

Collection methods: Emphasis here is on the rugosans. Tabulates, brachiopods, stromatoporoids, high-spired gastropods, and ostracodes are also present.
