Short description: Extinct subfamily of ammonites

Nodicoeloceratinae
Temporal range: Toarcian
[1]
Scientific classification e
Domain: Eukaryota
Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Subclass: †Ammonoidea
Order: †Ammonitida
Family: †Dactylioceratidae
Subfamily: †Nodicoeloceratinae

The subfamily Nodicoeloceratinae comprises early Jurassic ammonite genera that lived during early to middle Toarcian stage. Origin of this subfamily is unknown, but first genus Nodicoeloceras has evolved from Dactylioceras (Orthodactylites) or Kedonoceras.[1]

Validity

Sometimes, this taxon is considered to be invalid and is included in Dactylioceratinae. This is not so in the case of scientists that describe Mediterranean faunal province that values phylogenetic, morphological and paleobiogeographical importance of this subfamily.[1][2]

Taxonomy

Following genera are members of this subfamily:[1]
