This report covers 5 collections, all of which contain poorly preserved, distorted, fragmentary molds and casts of brachiopods, mollusks and echinoderm debris. Most of these fossils are indeterminate, but can be compared with better preserved material from nearby areas. All but one are probably Late Devonian (Famennian) in age. One collection (77ANS013A) may possibly be Early Mississippian, but a Late Devonian age cannot be ruled out for this collection either.
[It is obvious in reading the individual notes for each locality, that the citation above referring an Early Mississippian age for collection 77ANS013 is an error, what was obviously meant was collection 77ANS070A (see accompanying note) - RBB comment]
SUMMARY. The presence of possible Cyrtospirifer, rhynchonelloids and the large productelloid brachiopod suggest a Late Devonian (Famennian) age. The characteristic corals and brachiopods of thie typical Hunt Fork Shale are not present. Calcareous sandstones of this age have been mapped as a separate member of the Hunt Fork Shale elsewhere in the cnetral Brooks Range. Similar rocks lie just below the type Kanayut in the area east of Shainin Lake.
The collections are being discarded.
