Strangest Prehistoric Creatures To Rule The Earth
This was an ancient relative of todays sperm whale, which as we all know (or should know) is huge, eats lots of squid and has never been known to attack humans without provocation. Acrophyseter was the complete opposite; it was moderately sized, and didnt feed on squid but rather on other marine mammals and even on sharks! Its horriblelooking teeth were deadly weapons and have given Acrophyseter and its ancient relatives the nickname of killer sperm whales. Acrophyseters fossil remains have been found in Peru; it lived in the Miocene period, which seems to have been the best epoch for scary marine monsters including giant dolphins, colossal sharks and even monster penguins and seals.
