Domain: Eukaryota
Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda

Jeletzky, 1966
Genera and species
  • Groenlandibelus rosenkrantzi Jeletzky, 1966 (Birkelund, 1956)
  • Cyrtobelys fuchs et al 2012
  • Naefia Wetzel, 1930

Morphologically, its taxa seem to have some belemnoid characteristics, suggesting a possible intermediate relationship.[2]

Genera edit

Groenlandibelus Jeletzky, 1966 edit

Monospecific, Groenlandibelus rosenkrantzi Jeletzky, 1966 (Birkelund, 1956). The fossil range is from Campanian to Maastrichtian.[1] Some material originally was ascribed to Belemnoteuthis before being allocated its own genus.

Cyrtobelus Fuchs et al 2012 edit

Some taxa now assigned to the Groenlandibelus are now assigned to Cyrtobelus. Species:

  • Cyrtobelus birkelundae Fuchs et al. 2012
  • C. hornbyense Fuchs et al. 2012

The fossil range is from Upper Campanian to upper Maastrichtian with localities in Vancouver Island (BC) and West Greenland.

Naefia Wetzel, 1930 edit

The fossil range of Naefia is from Cenomanian to Campanian.[1]
