MATERIALEXAMINED.—Peyrère:oneventralMNHN.F. A46481 and two dorsal valves MNHN.F.A46482. — Abesse: nine dorsal valves MNHN.F.A46483, A46484 .

OCCURRENCE. — In the fossil record this species is known from the Neogene of the Mediterranean region. Today it lives in the eastern North Atlantic and the Mediterranean Sea, having a wide depth range from 3 to 1665 m ( Logan 1979, 1998; Logan & Long 2001).

REMARKS

Novocrania anomala is rare (12 specimens) in the studied material, found only in two localities. ffle material is poorly preserved, both outer and inner surfaces are usually worn but it corresponds well with that hitherto described ( Logan 1979, 1998; Logan & Long 2001; Álvarez & Emig 2005). ffle shell is small with maximum length 15.6 mm, subcircular in outline, wider than long. ffle posterior adductor muscle scars are large, subcircular, situated near posterior margin in both valves. ffle anterior adductor muscle scars are oval, elevated. On some specimens mantle canals can be observed ( Fig. 2C, D ). fflis is the only inarticulate brachiopod in the investigated assemblage.
