Title: Report on Referred Fossils ,  1979 (02/02)
Report by: William A. Oliver , Jr.
Referred by: David A. Brew , R. P. Morrell
Age: Middle Ordovician-Permian
Comment:Three of the coral-like objects were thin sectioned but none are identifiable and none are even certainly corals. One is sugguestive, however, of a favositid coral which in turn suggests a Mid Ordovician to Permian age.
Other megafossils are in the same blocks; if they give more helpful results, additional reports will be sent.

Title: Report on Referred Fossils ,  1980 (02/07)
Report by: Ellis L. Yochelson
Referred by: David A. Brew
Age: Devonian (Devonian?)
Comment:Collection 78RM382A was reported by William Oliver as lacking corals and as indeterminate as to age. I have examined the pseudocorals and suggest that they might be allied to "Dentalium" martini. Although this form is supposed to be a scaphopod it is not a mollusk and is a "worm" tube of some kind or another. The wall is thicker on one part of the circumference than on the remainder, a feature shown by the Alaska material. The form was originally described from the Columbus Limestone and I have seen it from the Cedar Valley of Iowa.
The organism has not been investigated and I can only add that the collections of the National Museum contain one specimen from Wisconsin and one from Colorado of Devonian age which conceivably belong to the same general group.Thus this Alaska collection might be Middle Devonian or at least Devonian. It is a long distance from Ohio to Alaska and I emphasize that this age determination is only a suggetion.
An indeterminate gastropod in the collection is a high spired form of mid-Paleozoic aspect (post Lower Ordovician and pre-Mississippian). This blue sky speculation of possible Devonian age is helped by the occurrence of similar gastropods in the Manitoba Group of western Canada. A mysterious "Dentalium" also occurs in this fauna but I have not examined the specimen.
Representative samples are being retained under number 10058-SD and will be placed in the Museum "worm" collection for future reference.
