Name: Stenorhynchosaurus ‭(‬narrow snout lizard‭)‬.
Phonetic: Sten-o-ryn-ko-sor-us.
Named By: María E.‭ ‬Páramo,‭ ‬Marcela Gómez-Pérez,‭ ‬Leslie F.‭ ‬Noé,‭ ‬Fernando Etayo‭ ‬-‭ ‬2016.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Sauropterygia,‭ ‬Plesiosauria,‭ ‬Pliosauridae.
Species: S.‭ ‬munozi‭ (‬type‭)‬.
Diet: Carnivore/Piscivore.
Size: Holotype roughly about‭ ‬4.3‭ ‬meters long.
Known locations: Colombia‭ ‬-‭ ‬Paja Formation.
Time period: Barremian of the Cretaceous.
Fossil representation: Almost complete skull and post cranial skeleton.

       Fossil remains of Stenorhynchosaurus were first discovered in‭ ‬2000,‭ ‬and later excavation of the fossil site between‭ ‬2004‭ ‬and‭ ‬2005‭ ‬revealed an almost complete skeleton.‭ ‬Also in‭ ‬2005,‭ ‬paleontologist Oliver Hempe came to the theory that this pliosaur possibly represented a species of the genus Brachauchenius.‭ ‬Later more detailed study however identified this pliosaur as a distinct genus,‭ ‬and hence Stenorhynchosaurus became established as the new name.
       Stenorhynchosaurus is noted for having a narrow snout,‭ ‬which is also the main inspiration for the name.‭ ‬At a little over four meters in length for the holotype individual,‭ ‬Stenorhynchosaurus was small when compared to some of the monster pliosaurs such as Pliosaurus,‭ ‬and was likely a hunter of smaller aquatic organisms such as fish.
