haggarti — that lived 100-72 million years ago and could have been 7-19 m long. Wear on the jaws indicated the octopuses often crushed hard bones while asymmetric wear patterns suggested they were already highly intelligent.
The findings overturn the idea that ancient food chains were crowned by vertebrates alone.
