Livyatan Melvillei scale model.

Approximately 50 centimetres long. This is a reconstruction of the only creature that could rival Megalodon being the greatest predator ever to exist on earth.  This giant prehistoric toothed whale was also sculpted for the digital rendering to display in the new ocean exhibit at the Historyland museum in Hellevoetsluis. These monstrous whales would have grown to huge proportions measuring up to 18m in length weighing 50 metric tons. With the largest known functional teeth in the animal kingdom ever measuring up to 35 cm long root to tip they would have been phenomenal predators killing whatever they pleased.  It was a type of macroraptorial sperm whale that like the adult Megalodon sharks were on the top of the food chain and thus had no natural enemies.
