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
Groenlandibelus Jeletzky, 1966
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
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
The fossil range of Naefia is from Cenomanian to Campanian.[1]
