Species: ‭ ‬L.‭ ‬qianweiensis‭ (‬type‭)‬.
Diet: Carnivore.
Size: Estimated between‭ ‬6‭ ‬and‭ ‬7‭ ‬meters long.
Known locations: China‭ ‬-‭ ‬Sichuan Province‭ ‬-‭ ‬Dashanpu/Upper Shaximiao Formation.
Time period: Oxfordian of the Jurassic.
Fossil representation: Partial but otherwise very well preserved individual including skull and post cranial remains.‭ ‬A femur of a juvenile has also been attributed to the genus.

       Leshansaurus was a mid-sized theropod of the late Jurassic of China with jaws that were proportionately longer than most other theropods of the time that also widened slightly.‭ ‬These features might denote a prey specialisation for Leshansaurus,‭ ‬perhaps somehow helping it to deal with the large variety of relatively small stegosaurs of the time such as Chungkingosaurus,‭ ‬Gigantspinosaurus and Chialingosoreus‭ (‬e.g.‭ ‬longer reach for biting over stegosaur plates and spines‭)‬.‭ ‬However this is only early speculation.‭
       At the time of the initial description Leshansaurus was described as an allosauroid and possible relative to its contempory Sinraptor.‭ ‬However a cladistic analysis was not published at this time,‭ ‬and later observers have suggested that Leshansaurus might actually be a megalosauroid theropod.
