Belosaepia, occasionally incorrectly Belosepia,[2] is a genus of cuttlefish-like cephalopod known from the Eocene.[1]

Morphology

Belosaepia reached 18 centimetres (7.1 in) in length and 5 centimetres (2.0 in) across; it had a large siphuncle that penetrated its oblique septa.[1] The shell was endogastrically coiled.[1] It had a small belemnite-like guard, which took the form of a short horn at the posterior end of the shell;[1] usually, only a small portion of the shell closest to the guard is preserved. The chambers in the shell closely resemble those present in the cuttlebone of modern cuttlefish.[1]

Ecology

Belosaepia lived close to the sea floor.[1]
