Comment: | Age: Oligocene. The doubtfully identified Bruclarkia suggests assigment to the "Lincoln Stage" of the Pacific coast megafaunal chronology of Weaver and others (1944). It is closely related to the well-known "Lincoln" index species B. columbiana, differeing from it principally in having a much higher spire. In northwestern Washingtopn, B. fulleri is restricted to the lowermost of Durham's "Lincoln" zones, the Molopophorus stephensoni zone. |
