This report covers 11 collections from the Delong Mountains Quad. of which 4 are from the Kogruk Limestone, 5 are from a Mississippian shale-chert-sandstone sequence and 2 are from Triassic cherts. All collections from the Kogruk are float and three of these consist only of indeterminate crinoid columnals. The fourth is a lithostrotionoid coral, typical of this late Mississippian formation in the western Brooks Range. |

| Comment: | These three collections [30107, 30461, F-1] are pelmatozoan calcarenite composed of large crinoid columnals and other bioclastic debris. The rock type is characteristic of some beds in the Kogruk, but the fossil debris is indeterminate. |
