Line 3: Line 3:
Lambeoceratids are characterized by long dorso-ventrally flattened shells with the dorsal and ventral sides about equally rounded, acutely joined along the mid plane. Shells may have reached lengths of about a meter, with a maximum width of about 25cm and height (thickness) of around 10cm (3ft x 10in x 4.5in.). The apical end in broadly rounded, the siphuncle narrow and near central.

''Lambeoceras'' had been included with ''Gonioceras'' in the [[Gonioceratidae]] by Teichert in the Treatise part K, 1964, with which it bears only superficial reseblence but was recognized by Rousseau Flower (1968) as being derived from the [[Actinoceratidae]], and possibly from ''Kochoceras''. where it split from the [[Hurinidae]].

While its lifestyle is unknown for sure, it seems that ''Lambeoceras'' may have spent it time moving close over shallow open sea bottom or burried in shallow sediment, hidden from view.
