Protosphyraena perniciosa
Protosphyraena perniciosa was a medium-sized predatory fish from the Late Cretaceous of Kansas. It resembles swordfish in many ways, but is not especially related to them. I don't actually know very much about fish, and this is my first proper reconstruction, so it may be errorful. I got most of my information from Mike Everhart's stupendous Oceans of Kansas.
