Strongylosteus

Strongylosteus hindenburgi is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.[1][2]A large member of the Chondrosteidae and the largest non reptilian marine vertebrate of the Posidonia shale, with a size between 3 and 4.5 m, and an estimated weight over 800 kg to 1 tonne. Has been suggested as a junior Synonym of Chrondrosteus, although there haven't been any new revisions about the status of the genus. It is related to modern sturgeons, but with a different kind of mouth than common species, made for hunting prey in open waters, with a strong lower jaw, similar to modern Beluga Sturgeons.
