Cornuodus erectus FAHRiEUS, 1966 (=Drepanodus longibasis LINDSTROM, 1955). Opis
Diagnosis. - Elements of the apparatus with deep, conical basal cavities, bases of oval crosssection, cusps bent knee-like.
Remarks. - LOFGREN (1978) first properly identified the main element types of the Cornuodus apparatus and distictions between species. Despite the very generalized morphology of the elements in the apparatus, up to six discrete element types can be distinguished in samples with numerous specimens of the genus. The standard notation of the element types proposed here is, obviously, very tentative and based on some similarity to Drepanodus. This does not necessarily mean that these genera are closely related to each other. An alternative interpretation is suggested by the close similarity in the apparatus organization to that of Dapsilodus. Especially the elements with widened bases clearly seem homologous in these apparatuses. If Dapsilodus is related to Besselodus, a genus with the apparatus organization known from a complete cluster (ALDRIDGE 1982), this wide element type would be the ne one. There are elements in the apparatus of Cornuodus that may be homologous to tr elements of higher conodonts but their extremely simple morphology makes any interpretation difficult.
