Submitter notes: I found this specimen a couple years back in the Arkona Formation. I have not been able to ID it. It is quite large for a pelecypod from the Arkona. This specimen is 7 cm across. Most Arkona formation pelecypods are a cm or less. Any help in ID'ing this specimen would be appreciated.
