Brief statement of problem and remarks (from collector):
With the possible exception of a belemnite reportedly identified on the spot but not collected (Alaskan Branch paleo file, p. 1706-1707), no fossil Mollusca are known to have been found heretofore in the Yakutat group in the type area or adjoining parts of the Yakutat and Malaspina districts. The group is now considered to be probably Cretaceous and possibly largely or entirely of Late Cretaceous age (USGS Oil and Gas Inv. Map OM 189). The present collections are from argillite near a depositional contact with greenstone, a relationship similar to that described in the type area by Tarr and Butler (USGS Prof. Paper 64, p. 152-154), and hence are probably from the basal part of the Yakutat group.
