Where: Oklahoma (34.3° N, 96.8° W: paleocoordinates 25.6° S, 63.0° W)
• coordinate based on political unit
• local area-level geographic resolution

• Placotriplesia beds are in the upper part of Fitzhugh Member, but it is not clear from data presented by Amsden whether a Sheinwoodian or Homerian age is more likely.
• group of beds-level stratigraphic resolution
Environment/lithology: deep subtidal ramp; shelly/skeletal grainstone and packstone
•SEP environmental call based on given info and on Amsden (1968) JP 42 sup. to 3
