Where: Wisconsin (43.0° N, 88.2° W: paleocoordinates 21.4° S, 53.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Brandon Bridge Formation, Telychian (438.5 - 433.4 Ma)
• STRATIGRAPHIC RELATIONS: From the Brandon Bridge Fm, which unconformably overlies the Kankakee Dolomite, and conformably grades up into the Waukesha Dolomite. AGE: Latest Llandovery; based on graptolite biostratigraphy; Monograptus spiralis. Conodonts from the top of the Brandon Bridge Fm also support a late Llandovery-early Wenlockian age. Early Telychian according to Haug et al., 2014. STRATIGRAPHIC POSITION: From a 12 cm thick layer overlying the lowest 2 m of strata.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; lithified mudstone and lithified dolomite
Size class: macrofossils
Preservation: soft parts
Collection methods: COLLECTOR: Not stated in text. REPOSITORY: University of Wisconsin.
