Chondrosteidae
Chondrosteidae /ˌkɒndroʊstiˈaɪdiː/ is a family of extinct marine actinopterygian fishes in the order Acipenseriformes. Three genera are known from the Early Jurassic of Europe, Chondrosteus, Gyrosteus, and Strongylosteus. Included species were of large size, with body lengths ranging from 2 metres (6.6 ft) up to 7 metres (23 ft). Their skeleton was largely made up of bones (unlike living chondrosteans), but ossification was reduced compared to other ray-fins.
