Leptostyrax is an extinct genus of mackerel sharks that lived during the Cretaceous. It contains two valid species, L. macrorhiza and L. stychi, found in North America, Europe, Africa, and Australia .[2]
Vertebrae tentatively assigned to L. macrorhiza suggest lengths of 6.3–8.3 m (21–27 ft), making it one of the largest Cretaceous sharks.[6]
