Protosphyraena Scale Protosphyraena pernicosa

Protosphyraena was a large predatory fish adapted to high-speed swimming. It’s sharp, conical snout and forward-facing anterior teeth were probably used in a torpedo-like attack to spear through prey head-first at great velocity. Every fin of this incredible fish was adapted to provide optimal speed and acceleration. The speed of Protosphyraena might have been unmatched by anything, reptile or fish, in the Western Interior Seaway.
