This report concerns 9 collections, comprising over 100 specimens, from Middle Paleozoic through Late Triassic age. The unusual Late Triassic assemblage (FET-1630) includes Spondylospira), corals, and a variety of molluscan genera. Similar associations are known from southeastern Alaska and the north shore of Iliamna Lake (see Martin, 1926, USGS Bull. 776, p. 59-60, 70-73).

Three collections are probably of Permian age (FET-1680, FET-1680A and WCG-185) and another (FET-1684) may possibly be Permian, although Carboniferous cannot be ruled out. An Early Mississippian age is possible for FET-1676.

The occurrence of Carboniferous, Permian, and Triassic fossils, in corkcs from the south end of the Alaska-Yukon geanticline (of Cady), indicates that equivalents to rocks of the Holitna group, are present in the Lime Hills region.

Of the remaining three collections, only WCG-187 can be dated. It is probably Devonian.
