Euteleostei


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. It is divided into Protacanthopterygii and Neoteleostei.

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