FIGURE 15. Cretaxinus hurumi gen. et sp. nov. (A) Lateral view of left valve of articulated internal mould, showing broadly rounded ventral margin. (B–C) Detail of anterior margin showing weak and descending anterior adductor muscle scar fading posteriorly and its serrated dorsal margin. (D) Anterior view showing shape and size of lunule. (E) Dorsal view showing shape of the posterodorsal margin and escutcheon. (F–G) Cross-section through a ligament showing its thickness. (H) Lateral view of left valve of articulated internal mould with less rounded margin than specimen shown in (A). (I–J) Detail of a anterior margin showing weak anterior adductor muscle scar fading posteriorly. (K–L) Anterior view showing shape and size of the lunule, anterior adductor and pedal retractor muscle scars. (M) Dorsal view showing shape of the posterodorsal margin and escutcheon. (N) Lateral view of right valve internal mould. (O–P) Detail of anterior margin showing very weak anterior adductor muscle scar visible only at its anteriormost portion. (A–G) PMO 225.128, (H–M) PMO 217.172, (N–P) PMO 225.136. Scale bars 10 mm.
