Report on Referred Fossils

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. |

| Comment: | Fossils, almost entirely pelecypods of the genus Buchia (=Aucella), are abundant locally in the lower zone of interbedded mudstone and sandstone and sparsely distributed in the overly mudstone, but most of the beds of the Kisimilok Formation are relatively barren of fossils. The collections have been examined by David L. Jones, of the Geological Survey, who reports (written commun., 1961, 1963): Jones concludes that the collections containing B. "sublaevis" are probably from early Valanginian rocks, and that the probable presence of B. subokensis suggests a Berriasian age for some of the section (written commun., 1963). On the basis of the pelecypod fauna, the Kisimilok Formation is assigned an Early Cretaceous age. A correlation with part of the Okpikruak Formation of Early Cretaceous age (Gryc and others, 1951, p. 159-160) is suggested on the basis of the Buchia species, following the zonation of Imlay (1959, p. 165).
