(narrow snout lizard).
Named By: María E. Páramo, Marcela Gómez-Pérez, Leslie F. Noé, Fernando Etayo - 2016.
Classification: Chordata, Reptilia, Sauropterygia, Plesiosauria, Pliosauridae.
Species: S. munozi (type).
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.
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.
more detailed study however identified this pliosaur as a distinct
genus, and hence Stenorhynchosaurus became
established as the new
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.
