Abstrakt

Delphinites (Family Neocomitidae, Subfamily Platylenticeratinae) is described from Traill Ø and Wollaston Forland in North-East Greenland, where it is represented by two new species of the subgenus Pseudogarnieria: Delphinites (Pseudogarnieria) christenseni n.sp. and Delphinites (Pseudogarnieria) donovani n. sp. The material indicates the presence of equivalents of the Delphinites (Pseudogarnieria) undulatoplicatilis Zone of the Russian Platform, and of the Thurmanniceras pertransiens Zone of South-East France. These Greenland occurrences are therefore correlatable with the lowest biozones of the Valanginian Stage in both the Boreal and the Tethyan realms. The genus was previously known almost exclusively from the Russian Platform, and it has an essentially marginal Boreal distribution.
