Bobasatraniiformes

Bobasatraniiformes is an extinct order of durophagous ray-finned fish that existed from the late Permian to the Middle Triassic in both marine and freshwater environments.

The order includes two families: Bobasatraniidae, with the genera Bobasatrania, Ebenaqua, and Ecrinesomus, and Dorypteridae, comprising only the genus Dorypterus (monotypy).

Bobasatraniiformes had a somewhat global distribution; fossils are found in Africa (Madagascar), Asia (Pakistan), Australia, Europe, and North America.

[1] Most bobasatraniiforms were small [25 centimetres (9.8 in) or less], but some species of Bobasatrania grew up to 1.2 metres (3.9 ft) long or larger.

Instead, they possessed strong tooth plates used to crush shelled prey animals similar to Modern osteoglossomorphs (Teleostei).
