Colobodontidae is an extinct family of marine stem-neopterygian fish known from the Triassic of Asia and Europe. It contains at least three genera: Colobodus, Crenilepis and Feroxichthys;[2] the genera Chaohuperleidus and Gabanellia may also belong to the family.[1] The colobodontids typically were medium-sized, somewhat deep-bodied fishes with a durophagous diet.[3] Like most other stem-neopterygian families, it was traditionally placed in the paraphyletic order Perleidiformes,[2] but in 2024 it was moved to the new, monotypic order Colobodontiformes.[4]
