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]

gollark: I should be getting a few reds in december because I traded that ND from ages ago for an IOU for 4 new releases, 30 reds and 30 balloons.
gollark: I have an excess of aeons and a shortage of reds.
gollark: I got 18 AP hatchlings and it took me *ages* to name them all...
gollark: The barrier to entry is low, so honestly quite a lot of them are bad.
gollark: Those are the second-rarest kind, yes.
