Where: Iowa (42.2° N, 90.6° W: paleocoordinates 21.1° S, 55.6° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Farmers Creek Member (Hopkinton Formation), Telychian (438.5 - 433.4 Ma)

• "Apparently limited to the Late Llandoverian (C4)."

• member-level stratigraphic resolution

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

Collection methods: I have combined four separate collections listed, with abundances, in table 45.38, as well as other taxa mentioned in text. (Table includes echinoderms and brachiopods only.) Community is said to be similar to Stricklandia laevis Community of Witzke and Johnson (1999, PBDB ref. 7006, PBDB coll. 25038), but the collections listed here are different from those listed in Witzke and Johnson.

Purpose of describing collection: paleoecologic analysis
