Two pre-Permian collections in this shipment contain brachiopods. This report, together with that of Armstrong dated 1/12/72, completes the work on this shipment.

Note: In collating this report with Armstrong's, please change the field locality of USGS 23451-PC to 71ADt283(-100 ft.)
Report by: J. Thomas Dutro , Jr.
Referred by: Robert L. Detterman
Age: Carboniferous
Formation: Wahoo Limestone (Wahoo Limestone (Lisburne Group))
Comment:In addition to the coral this collections: echinoderm and fenestrate bryozoan debris, Archimedes, and fragmentary brachiopods, possibly Neospirifer and Derbyia. The foramifers from 50 feet below indicate a Zone 21 age; and these fossils are interesting in that they provide clues as to other elements that occur in the upper part of the Wahoo Limestone.
