Colobodontidae

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; the genera Chaohuperleidus and Gabanellia may also belong to the family. The colobodontids typically were medium-sized, somewhat deep-bodied fishes with a durophagous diet. Like most other stem-neopterygian families, it was traditionally placed in the paraphyletic order Perleidiformes, but in 2024 it was moved to the new, monotypic order Colobodontiformes.

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
