We once dubbed elephants among the cutest, yet most dangerous animals. We may be looking to retroactively remove it based on its prehistoric ancestor, the Platybelodon. During the Miocene Epoch, the lands of Asia were once inhabited by this strange looking Proboscidea. What warrants a spot on this list of creepy-looking prehistoric beasts, you ask? There’s just something about its odd-shaped mouth that we don’t like. The shovel-like shape, the two flattened modified incisors protruding from the lower jaw… it’s weird, very uncanny, and more than what we’re comfortable with.
