Where: Indiana (40.8° N, 86.3° W: paleocoordinates 29.3° S, 47.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kenneth Limestone Member (Wabash Formation), Pridoli (423.0 - 419.2 Ma)

• member-level stratigraphic resolution

Environment/lithology: deep subtidal; limestone

• "Geographic and stratigraphic relations with associated communities make a BA 5 assignment reasonable, as does the generic composition of the community. [Reasons for low diversity unknown.]"

•SEP environmental call based on given description and knowledge of regional geology

• "The occurrences are in beds a few cm thick, consisting of fine-grained sediment, typically with a very high percentage of articulated shells."

Reposited in the USNM

• Abundances stated in text.
