Groenlandibelidae is a family of coleoid cephalopods believed to belong to the spirulids.
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]
