(in consultation with M. Gordon, Jr. and O. L. Karklins) Most of the brachiopods are not well preserved, but the samples are small enough to warrant keeping them in the P&S reference collection. The ammonites, on the other hand, are better than those that Gordon examined for his report on shipment no. A-68-12 from the same locality. They are the first specimens of the genus Uraloceras to be identified in the Western Hemisphere, and therefore constitute an important collection.

All except sample 23476-PC are Permian or at least not apparently other than Permian. No. 23476 has only fenestellids that might well be Permian, but cannot be determined at present. No. 23480 has a suite of brachiopods, clams, a possible chiton, and other things that do not look like those in the other samples, so a different age was suspected. The bryozoans indicate a Permian age, however, and in fact suggest an early Late Permian age.

Brief statement of problem and remarks (from collector):
Nine of these ten suites of fossils were collected during detailed mapping in the structurally complex area in the vicinity of the Denali-Totschunda fault junction. Field identification suggests all are Permian. Corroboration of our field identification is requested. The remaining suite (71-ARh-150) is an additional collection of ammonites from the Nabesna Mine area. An earlier collection (68-ARh-77) from this area has been reported on by M. Gordon, Jr. (shipment A-68-12, rept. 10/23/69).
