Attachment scars of the brachiopod Coenothyris vulgaris (Schlotheim, 1820) from the Muschelkalk of Upper Silesia

Characteristic attachment scars of Coenothyris vulgaris (Schlotheim) occur in the Muschelkalk sequence of Upper Silesia. Their variability indicates· that the pedicle could be differentiated terminally into well-defined "rootlets". The pedicle allowed the brachiopods to colonize an otherwise inhospitable, soft-bottom environment.
