Three novel features are described in steinkerns of Hypomphalocirrus rugosus Linsley from the Middle Devonian Rogers City Limestone of Michigan.

The two other features are more enigmatic. They have a less stereotyped appearance and location. The first is interpreted as a field of mantle point-attachments and the other as a product of partial shell dissolution. Comparisons with extant and fossil molluscs confirm that the two features ascribed to biologic origins are within the scope of molluscan soft-part and shell attachment morphologies. 12 pp., 11 figs, 4.…
