Abstract.  The ammonoid beaks found for the first time in the Urals and belonging to the Late
 Carboniferous goniatitids Prothalassoceras, Gleboceres, Aristoceras and Eoasianites and
 prolecanitid Uddenites and the lower and upper beaks with unknown assignment sirnilar to
 the former are described.  In Aristoceras the fragmentary preserved radula was found within
 the body chamber.  The beaks from the Urals are compared to those from the Uruguay, USA
 and Germany.  The environmental conditions in Southern Urals at the time of the burrial of the
 beaks are discussed.  Short review on the diet and feeding habits of Recent coleoids is given.
 On the basis of the morphological data obtained the general scheme of the beak structure of
 goniatitids and prolecanitids is concluded. lt conforms to that of  recent coleoids.
