| Comment: | This collection, submitted as Permian, was forwarded to me by Ralph Imlay who recognized that it contains Triassic kinds of bivalves. In fact, it includes species of Amussium (sensu lato), Minetrigonia, and Palaeopharus? which are elements of a fairly diverse molluscan fauna known from several localities on Cape Kekurnoi. It has been collected previously at or very close to your locality. Included in this fauna in other collections are the ammonites Halorites and Alloclionites which date it as early late Norian (or very latest middle Norian at the oldest).
Jack Miller collected some of this same fauna last summer from a limestone boulder in a volcanic agglomerate on the large island southwest of VABM Hike (his locality 80AJM5).
This collection will be returned to you, as requested. |

Both collections in this shipment are of post-Permian age. The collection with the large amount of coralline material (80ADt173) is Upper Triassic, perhaps Norian. The yellow-weathering calcareous sandstone (80ADt175) is probably Lower Jurassic.
George Stanley is examining the corals and will give additional details later. I am turning the other collection over to Ralph Imlay who will report on it together with the other Jurassic collections which you are shipping him.
This report confirms our telephone conversation of 8/20/80. |

| Comment: | This yellow-weathering, sandy limestone contains molluscan fragments, including Weyla? sp. and a number of gastropod molds and casts. Weyla has been found in Lower Jurassic beds at several places in south-central and southwestern Alaska. |
