Diplocaulus magnicornis
Diplocaulus magnicornisDiplocaulus magnicornis was an aquatic ambush hunter that prowled the muddy bottoms of Permian river systems and swamps. Its iconic boomerang-shaped skull functioned like a hydrodynamic foil, generating rapid vertical lift as the animal lunged upward to seize passing fish. Dorsally placed eyes and a flattened torso allowed it to lie virtually concealed beneath sediment while surveying the open water above.
