Stratigraphic range: Lower Cretaceous
Kinds of fossils: Mollusks
Quadrangle or area: Point Hope 1:250,000
Shipment No.: A-61-5M
Referred by: Campbell, Russell H.
Report prepared by: Jones, David L.
Date: 12/31/1963

The following report is a re-evaluation of Buchias collected by Russ Campbell and reported on by me in 1961. The identification of B. "sublaevis" rather than B. crassicollis changes the age to early Valanginian rather than middle or late Valanginian. The probable presence of B. subokensis suggests a Berriasian age for some of the section at Point Hope.

Locality data are given in the previous report.

Brief statement of problem and remarks (from collector):
Chief problem is ages of the units in this little known part of Alaska. Fossils are generally very rare in these rocks and this collection is from beds representing about 10,000-15,000 feet of Jurassic and/or Cretaceous strata.
