Also known as Owen's Branch; OBB
Where: Clinton County, Kentucky (36.9° N, 85.1° W: paleocoordinates 23.1° S, 33.3° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Gnathodus texanus conodont zone, Fort Payne Chert Formation, Osagean (352.0 - 343.0 Ma)
• JA: originally entered as late Osagean; falls entirely within the Gnathodus texanus zone (Ausich and Meyer 1990), which in turn is Chadian to Arundian (Work and Mason 2004)
• group of beds-level stratigraphic resolution
Environment/lithology: reef, buildup or bioherm; green shale and packstone
•
•However, Krivicich et al. (2014) report these taxa only from the green shale, which are the "bottom" beds. This is described as a green shale packstone.
Size class: macrofossils
Reposited in the OSU, USNM
