Bobasatrania is an extinct genus of prehistoric bony fish that survived the Permian-Triassic extinction event. Fossils of Bobasatrania were found in beds of Changhsingian (late Permian) to Ladinian (Middle Triassic) age. It was most speciose during the Early Triassic. The genus was named after the locality Bobasatrana in northeast Madagascar, from where the type species was described. 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, with some of the best examples coming from the Wapiti Lake region of British Columbia, Canada. They have a distinctive diamond-shaped body, forked tail and long thin pectoral fins. B. ceresiensis was about long. The structure of their teeth suggests they fed on small shelled animals.
