Succession and Speciation of the Pelecypod Aucella

ABSTRACT The pelecypod Aucella, of latest Jurassic and earliest Cretaceous age, has been subdivided into more than a hundred species on the basis of mirnor differences without allowing for biological variation, or for variation due to crowding that is normal for an attached gregarious pelecypod. As a result, in any large collection from a single locality, specimens can be selected that fit the definitions of a number of species and yet these so-called species are connected by many specimens showing transitional characteristics. Such an assocition appears, therefore, to represent a single variable population. If the species of Aucella are defined making allowance for variation, the number of species is greatly reduced, but the specific concepts can be grasped readily by geologists and used for mapping purposes. Seven zones based on species of
Aucella can now be recognized easily in the field in North America, as has been demonstrated by geologists of the U.S. Geological Survey. |
