156 ADVANCES IN PALAEOICHTHYOLOGY Therefore, biostratigraphic correlations are made. The northern Sigurdfjellet and Kapp Kjeldsen faunal divisions are equivalent to the southern Austfjord Member. This is based on their Doryaspis – Gigantaspis association (Fig. 2). The southern Dicksonfjord Member is correlated with the northern Keltiefjellet faunal division due to the common occurrence of Doryaspis nathorsti and Arctolepis decipiens (Fig. 2). The northern Stjørdalen faunal division is not clearly established due to the lack of recent faunal information. However the occurrence of Doryaspis minor (N. Heintz 1960) in this division is considered as equivalent of the presence of Doryaspis lyktensis in the southern Dicksonfjord Member (Fig. 2).

Lukševics and Mr. I. Zupinš (Riga, University of Latvia) who organised the Walther Gross Symposium and received one of us for the congress and the following field trip. This paper was substantially improved by the review of D.K. Elliott (Flagstaff, Northern Arizona University) and an anonymous reviewer. References Blieck A., Goujet D., Janvier P. 1987.

Vūdbejas formācijas biostratigrāfiskā korelācija (apakšējais devons, Špicbergena) Daži 1969. gada franču ekspedīcijas rezultāti VINCENTS PERNĒ un VINCENTS DJUPRĒ Līdz šim tie ģeologi un paleontologi, kas pētī Vūdbejas formāciju (apakšējais devons, Špicbergena), izmanto atšķirīgas stratigrāfiskās skalas. Ģeoloģijā tiek izmantota litostratigrāfisko vienību shēma, kas izstrādāta pēc griezumiem Diksonfjorda-Austfjorda rajonā, turpretī paleontoloģiskos pētījumos izmanto biostratigrāfisko shēmu pēc griezumiem Vudfjorda rajonā. Plašu paleontoloģisko materiālu abos minētajos rajonos ieguva 1969. gada Francijas ekspedīcijas (CNRS-MNHN) dalībnieki. Šis materiāls izmantots šajā darbā pirmajai paleontoloģisko un litostratigrāfisko vienību korelēšanai. Ir piedāvāts šāds korelācijas variants: Sigurdfjelletas un Kapkjeldsenas faunas vienības ir Austfjorda ridas laterālie ekvivalenti, bet Keltiefjelletas un Stjerdalenas vienības Diksonfjorda-Austfjorda rajonā ir ekvivalentas Diksonfjorda ridai.
