Brief statement of problem and remarks (from collector):
These fossils are the best and most prolific zone yet found in this area, and appear to be part of a clastic rock unit dated as Upper Devonian on basis of earlier collections. Ref. A-64-17, A-67-6, 16AMt-64a (Bull. 872, p.102), A-63-10M (62ACh-12f).
