Chondrosteiformes, an extinct order of ray-finned saltwater fishes (class Actinopterygii) comprising a single family Chondrosteidae. These fishes were prominent in seas during the Early Triassic to Late Jurassic (from 251 million to 146 million years ago). Some species were suctorial feeders that probably gave rise to present-day sturgeon.
