Middle Ordovician conodonts from allochthonous limestones at Hoeyberget, southeastern Norwegian Caledonides

Middle Ordovician (llandeilo-early Caradoc) conodonts are recorded from the limestone at Hoeyberget, southern Norwegian Caledonides. The conodont fauna, including Pygodus anserinus Lamont & Lindstroem and Baltoniodus variabilis (Bergstroem), corresponds to the upper part of the Pygodus anserinus and the lower part of the Amorphognatus tvaerensis conodont zones. On the basis of the stratigraphic position the overlying black shale unit is correlated with the upper Nemagraptus gracilis and the Diplograptus multidens graptolite zones.
