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]

The cladogram is based on Near et al. (2012) and Betancur-Rodriguez et al. 2016.^[5] They explored the phylogeny and divergence times of every major lineage, analysing the DNA sequences of 9 unlinked genes. They calibrated (set actual values for) branching times in this tree from 36 reliable measurements of absolute time from the fossil record.^{[6][clarification needed]}
