What did ancient octopus fossils reveal about their diet?

Fossilized beaks of ancient octopuses showed distinct wear patterns suggesting they routinely crushed hard bones and shells of their prey.

How large were some ancient octopus species?

Some ancient octopus species were estimated to reach up to 19 meters in length, making them among the largest invertebrates on record.

What does the wear on ancient octopus beaks suggest about their behavior?

The wear patterns on the beaks suggest these ancient octopuses were powerful and behaviorally sophisticated predators, likely using their arms and beaks to process hard prey.

Some species reached up to 19 meters long.
These creatures were top predators in Cretaceous oceans.

Fossil Study Reveals 19-Meter Kraken-Like Octopuses

Ancient octopus species from the Cretaceous period were colossal, bone-crushing predators, according to recent research. Analysis of numerous fossilized beaks, some dating back 100 million years, indicates these creatures were far more than just large versions of modern octopuses.

These ancient cephalopods, some estimated to be up to 19 meters long, likely dominated the marine food web. Their beaks displayed significant wear patterns, suggesting they routinely crushed hard bones and shells. This predator strategy might have included preying on large marine reptiles like mosasaurs.
