This report covers 10 collections from the McCarthy C-1, C-2, and C-3 quadrangles, Alaska, made by D.L. Jones in 1972. Brachiopods from some of these have been identified by J.T. Dutro, Jr. The age, as suggested at the time the sections were received, is Early Permian, probably late Wolfcampian equivalent. |

[Note by Blodgett: This report by C.L. Rowett (prepared by J.T. Dutro, Jr.)
This report covers the 8 collections that contain corals from these three shipments. The Early Permian age assignment given by fusulinids and brachiopods, is substantiated. Rowett suggests that the collections with Sinopora and Tachylasma (USGS 23557-PC and 23564-PC) may be early Leonard.
The float specimen from Wiley Creek (USGS 23554-PC) is a Lithostrotion (Siphonodendron which, according to Rowett, is confined to the Carboniferous. It will be sent to A.K. Armstrong for examination.
The collections are being retained. |

This report covers 13 collections, from the McCarthy C-1, C-2, and C-3 quadrangles, made by D.L. Jones in 1972. Fusulinids were found in 8 collections and will be reported separately by Ray Douglass. Corals from 5 collections are being studied by C.L. Rowett. All evidence points to an Early Permian (Wolfcamp) age. Brachiopods are listed and discussed below.
The brachiopods are like forms reported by Waterhouse and from early Permian assemblages in the Yukon Territory. They correlate to some part of his Zone E, perhaps Zone Ey.

The material is being retained. |
