'Costistricklandia' castellana-Eospirifer Community, eastern Iowa (Silurian of the United States)

Where: Iowa (42.0° N, 91.0° W: paleocoordinates 21.1° S, 56.0° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Scotch Grove Formation, Telychian (438.5 - 433.4 Ma)

• "Late Llandoverian (late Telychian) and possibly earliest Wenlockian (celloni and amorphognathoides zones)."

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; dolomitic, shelly/skeletal wackestone

• "skeletal debris unabraded and commonly articulated...evidence of storm currents rare to absent...position below storm wave base indicated..Sedimentary evidence indicates significant deepeining for lowerr WElton strata...The Community must therefore be assigned a deeper [than BA 3] position...tentatively overlapping with transitional BA 4-5..nearl limits of photic zone, as occasional calcareous green algae are present.."
• "well-preserved molds in dolomitized skeletal wackestone fabrics (packed in part)"

Collection methods: Several localities (Table 50.1 and other occurrences mentioned in text) are combined. See Frest et al. (1999-PBDB ref. 4379) for more on echinoderms.
