ADVANCES IN PALAEOICHTHYOLOGY<br />

Therefore, biostratigraphic correlations are made. The northern Sigurdfjellet <strong>and</strong><br />

Kapp Kjeldsen fa<strong>un</strong>al divisions are equivalent to the southern Austfjord Member. This<br />

is based on their Doryaspis – Gigantaspis association (Fig. 2). The southern Dicksonfjord<br />

Member is correlated with the northern Keltiefjellet fa<strong>un</strong>al division due to the common<br />

occurrence of Doryaspis nathorsti <strong>and</strong> Arctolepis decipiens (Fig. 2).<br />

The northern Stjørdalen fa<strong>un</strong>al division is not clearly established due to the lack of<br />

recent fa<strong>un</strong>al information. However the occurrence of Doryaspis minor (N. Heintz<br />

1960) in this division is considered as equivalent of the presence of Doryaspis lyktensis<br />

in the southern Dicksonfjord Member (Fig. 2).<br />
