The two largest valves have a wide calcified inner lamella and are adult ( Figs 3C ; 4C ). In both specimens, the AMS are located within the cavity underlying the swelling of the ventro-lateral ridge but are weathered and cannot be satisfactorily observed. The RV (Fig. 5) is small, thin-walled, and has a narrow calcified inner lamella; it is an instar. The AMS pattern is plain, consisting of eight elongate scars organised in four parallel diagonal rows (Fig. 5C). The species identification of this juvenile is uncertain.
