Fossil of Pholidophorus bechei in the Urwelt-Museum Hauff Holzmaden, photographed by Ghedoghedo.

Belongs within: Actinopteri.
Contains: Pachycormidae, Teleocephala.

The Teleostei are a clade including the majority of living ray-finned fishes. Teleosts are characterised by the presence of one or more uroneurals, modifications of the vertebral neural arches that support the caudal fin (Bond 1996).

Synapomorphies (from Friedman et al. 2010): Internal carotid foramen present through parasphenoid; symplectic articulation on inner medial surface of quadrate; uroneurals present; pectoral propterygium fused to first pectoral fin-ray.
