Bobasatrania is an extinct genus of prehistoric bony fish that survived the Permian-Triassic extinction event.

The genus originated during the late Permian, survived the Permian-Triassic extinction event, and underwent a speciation event during the Triassic (approx 240M years BP) in the shallow coastal waters off the Pangaean supercontinent. Their fossils are therefore found throughout the world,^[1] with some of the best examples coming from the Wapiti Lake region of British Columbia, Canada.^[2] They have a distinctive diamond-shaped body, forked tail and long thin pectoral fins. The larger Permian species are up to a metre in length, though the Triassic species are considerably smaller. The structure of their teeth suggests they fed on small shelled animals.
