The first nautiloid from the Upper Ordovician of the Carnic Alps (Austria)

Orthoceras sp. cf. O. regulare (SCHLOTHEIM, 1820) from the Uggwa Limestone (Ashgillian) of the Carnic Alps is described. This species was previously known from Estonia, Germany and Poland. This is the first record of cephalopods in the Ordovician of Austria.
