(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. |

Comment: | The suite looks Permian. Nothing indicative of Upper Permian, so probably best to consider it Lower Permian (Asselian to Artinskian). |
