Top 10 Craziest Prehistoric Sharks

Stethacanthus: lived about 360 million to 340 million years ago, making it one of the very oldest sharks on this list! Often called the anvil shark

Hybodus: lived about 303.4 million to 66 million years ago and is possibly one of the longest living prehistoric sharks of all time. It’s definitely the longest living one on this list.

Cladoselache: lived more than 380 million years ago. While considered a shark, a Cladoselache has more in common with your average fish than your average shark today.

Edestus:Having lived about 300 million to 320 million years ago, the Edestus is another prehistoric shark that looks quite… odd. Also called the scissor-toothed shark.

Bluntnose Sixgill Shark:a shark that’s not even extinct! The bluntnose sixgill shark can trace its lineage back to the Jurassic era when dinosaurs roamed the Earth. 

 Ptychodus: was one of the largest prehistoric sharks, with some estimates placing is size up to 33 feet in length! Like today’s whale sharks it had a mouth full of teeth that were used to crush up .

Megalodon:Thought to be the largest fish and shark to ever live, megalodons were huge prehistoric sharks that were apex predators during their time. These giants lived from 23 million to 2.6 million.

Cretoxyrhina: lived during the Cretaceous geological period, a time where there were many large creatures in the ocean, all fighting for supreme dominance over others. 

Xenacanthus:Often called an eel shark, the Xenacanthus became extinct about 202 million years ago, making it another very old shark on this list. 

Helicoprion:also called the “buzzsaw shark”, lived about 290 million to 250 million years ago. This prehistoric shark also happens to be one of the most interesting additions to this list.
