Cupulocorona gemmiformis-Lecanocrinus pusillus Assoc., Waldron Member, Tennessee (Silurian of the United States)

Where: Tennessee (35.4° N, 88.0° W: paleocoordinates 29.7° S, 56.1° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Kockelella amsdeni zone, Waldron Member (Wayne Formation), Wenlock (433.4 - 427.4 Ma)

• member-level stratigraphic resolution

Environment/lithology: offshore ramp; ferruginous, glauconitic, shelly/skeletal wackestone

• "echinoderms generally disarticulated; holdfasts moderately common; brach's often articulated; no indication of winnowing or other signs of wave action; [Compared with Waldron sections to the north], deposition more offshore, in an area comparatively starved for clastic input, seems likely. The predominance of small echinoderms and the high brachiopod diversity suggesta outer BA 4"

•SEP environmental call based on given info

• "Moderately fossiliferous. Most frequently an echinoderm-rich wackestone with 20-40% skeletal debris...sand-sized detrital glauconite and ferric iron minerals..."

Collection methods: Abundances for four samples in table 45.41; these are combined for this collection.
