The real Diplocaulus

Diplocaulus magnicornis is recognized by the broad, boomerang-like projections at the back of its skull. Its small body and swimming tail belong to an extinct amphibian relative.

The unusual head has inspired several functional hypotheses. Its skull projections are directly documented, while their exact role in swimming or other behaviour remains debated.
