Euteleostei Explained

Euteleostei, whose members are known as euteleosts, is a clade of bony fishes within Teleostei that evolved some 240 million years ago, although the oldest known fossil remains are only from the Early Cretaceous.^[1] It is divided into Protacanthopterygii (including the salmon and dragonfish) and Neoteleostei (including the lanternfish, lizardfish, oarfish, and Acanthopterygii).^{[2] [3] [4]}

Taxonomy

The following taxa are known:

• Clade Pan-Euteleostei
  • Genus †Avitosmerus
  • Genus †Barcarenichthys
  • Genus †Beurlenichthys
  • Genus †Casieroides
  • Genus †Chardonius
  • Genus †Erihalcis
  • Genus †Gaudryella
  • Genus †Gharbouria
  • Genus †Helgolandichthys
  • Genus †Parawenzichthys
  • Genus †Santanasalmo
  • Genus †Scombroclupeoides
  • Genus †Tchernovichthys
  • Genus †Wenzichthys
  • Cohort Euteleostei
    • Superorder Lepidogalaxii
    • Superorder Protacanthopterygii

The divergence dates on the cladogram are based on Near et al. (2012), and the topology is based on Betancur-Rodriguez et al. 2016.^[5] In the topology of Near et al. (2012), Galaxiiformes were found to be sister to Neoteleostei instead. Near et al. (2012) explored the phylogeny and divergence times of every major lineage, analysing the DNA sequences of 9 unlinked genes. Near et al. also calibrated (set actual values for) branching times in this tree from 36 reliable measurements of absolute time from the fossil record.^[6]
