== Discovery == thumb|left|Strongylosteus hindenburgi skull close-upStrongylosteus hindenburgi is known from the Toarcian Posidonienschiefer Formation in southwestern Germany, specifically around Holzmaden and Dotternhausen. Initially identified by Pompeckj in 1914 as "Chondrosteus hindenburgi", hovewer the name was never formally published. Hauff (1921) mentioned it as a nomen nudum, and Hennig (1925) provided the first formal description, retaining the name but describing it in detail alongside additional specimens. Jaekel (1929) later reassigned it to the new genus Strongylosteus, correcting its taxonomic position.
