Where: Oklahoma (34.7° N, 96.6° W)

• Paleocoordinates: 31.1° S, 89.9° W (Wright 2013)

• coordinate based on political unit

When: Henryhouse Formation, Ludlow (427.4 - 423.0 Ma)

• Association is known from lower and middle Henryhouse. It is not clear from the text which of these is the source of this collection.

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; shelly/skeletal marl

Collection methods: Table 45.48, which gives abundances. I have added Bryozoa indet. and Ostracoda indet., which are mentioned in text but not listed in table. "The Bryozoan parts of this collection could not be relocated for counting..."
