Scientific name
Clupeocephala
Patterson & Rosen , 1977

The Clupeocephala are an overcohort of the Teleostei (bony fish i. E. S. ). With the exception of the osteoglossomorpha (osteoglossomorpha) and the elopomorpha (eel-like, among others ), they include all other (more highly developed) taxa of the real bony fish.

features

According to Arratia (1997) they are defined by seven skeletal synapomorphies :

  1. The retroarticular bone (skull bone) has no contact with the articular surface of the square leg .
  2. In the lower jaw are articulated leg (articular) and Angularknochen merged.
  3. No middle pharynx plates on the first to third basibranchial (middle bones at the base of the branchial arch under the hypobranchial) or on the hypobranchial cartilage.
  4. No pharyngeal teeth associated with gill arches 1–3.
  5. The neural arch of the first vertebra bearing the hypuralia (after the branching of the caudal artery) is reduced or absent.
  6. The two most anterior uroneuralia are long and separated from other bones.
  7. Six hypuralia or less.
