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 to with localities in Vancouver Island (BC) and West Greenland

Naefia Wetzel, 1930[]

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