Mr. Irvin L. Tailleur Alaskan Mineral Resources Branch U.S. Geological Survey Dear Irv: My conclusions regarding the following three of your collections from the De Long Mountains and Pt. Hope quads are: [see comments below] Specimens from all three of these localities have been added to the Triassic reference collections of the P&S Branch in Menlo Park, and the unwanted scraps from collections -35 have been returned to the Alaskan Branch. It would be interesting to have these processed for conodonts. Either L.C. Mosher at Univ. Arizona or Walter Sweet and his associates at Ohio State might be approached to do this. Many thanks for the materials on radiometric dates for the Triassic that you had duplicated for me, and for the other Xerox copies, too. |

Comment: | The fossils in this collection represent a species of "Posidonia" like that from just below the "chert member" of the "Shublik" on Monotis Creek (in unit 5 of Patton and Tailleur, 1964, fig. 74, p. 436) where it occurs with ammonites of Anisian (early Middle Triassic) age. As the actual stratigraphic range of this species is not known, the significance of its occurrence in the Pt. Hope region is open to interpretation. |
