Stippled frame denotes the μCT region of interest. h Virtual section through the 3D μCT dataset, anterior facing right. The asterisk denotes ingested sediment. i, j Right lateral and oral views of the surface-rendered 3D model of the upper beak (Additional file 3). k, l Left lateral and oral views of the lower beak. m Virtual section through the 3D μCT dataset showing the anterior part of the radula in sagittal section. n Volume rendering of the radula, oral view. The asterisk denotes ingested sediment, arrow points to the rhachidian tooth. o, p Dorsal and right lateral views of the shell, anterior facing down. Stippled line denotes the fin cartilage insertion. q, r Dorsal and left lateral views of the male reproductive system, anterior facing left";
