Parodoceratidae is one of five families of the Tornoceratoidea superfamily, a member of the Goniatitida order. They are an extinct group of ammonoid, which are shelled cephalopods related to squids, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloids.
Tornoceratoidea, also known as Tornocerataceae, is a superfamily of goniatitid ammonoids included in the suborder Tornoceratina. Tornoceratoidea, or Tornocerataceae, is essentially the Cheilocerataceae of Miller, Furnish, and Schindewolf (1957) in the Treatise Part L, revised to accommodate new taxa and new perspectives on the phylogeny.
In biological classification, taxonomic rank is the relative level of a group of organisms in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc.
In biological classification, the order is
- a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family. An immediately higher rank, superorder, may be added directly above order, while suborder would be a lower rank.
- a taxonomic unit, a taxon, in that rank. In that case the plural is orders.
