Fig. 1. Soft−tissue attachment structures in cephalopods from the Wissenbach Schiefer (early Eifelian). A. Bactrites gracile (Blumenbach, 1803), NHW 62.11/W−23/64, dorsal view, note the two different grayish bands (arrows) forming a lobe. B. Bactrites sp. A, NHW 402, dorsal view (B1), note two successive, slightly undulated grooves. Same specimen, lateral view (B). Same specimen, ventral view (B), note the small lobe in suture line. Same specimen, +
