       The unusual boomerang shape of the head has been a source of interest ever since its discovery.‭ ‬The two main theories are that it either functioned as a hydrofoil allowing it to move in strong currents,‭ ‬or that it made it impossible for other predators to swallow. It may have course been a form of recognition between members of the same species.
