This report covers eight collections of fossils from unnamed Lower Cretaceous and undivided Jurassic and Cretaceous rocks. Most of the fossils are poorly preserved and fragmentary, but the presence of Buchia crassicollis (Keyserling) indicates Lower Cretaceous (mid-to- late Valanginian) strata.


***
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.
