3

Its front teeth were weaker than its back teeth, which were stronger and more blunt.2

5

Its radius bone, in the front flipper, had two notches on the front edge, which is a special feature.2

Aurkikuntza
The first fossil, a partial skeleton, was found in the Guanling Formation in Guizhou, China. It was first named Mixosaurus panxianensis in 2006, but in 2010 Michael W. Maisch gave it its own genus, Barracudasauroides.12
Oraindik eztabaidagai
Scientists are still debating whether Barracudasauroides should be its own genus or just a species of Mixosaurus, because some think the differences are not big enough.2
