Meet the 19-meter Cretaceous kraken that swam with mosasaurs

Researchers found asymmetric beak wear in a 19-meter Cretaceous cephalopod, suggesting it had a side preference while feeding.

The pattern is being read as evidence of active hunting and more specialized behavior, not passive scavenging.

The study supports the idea that giant ancient cephalopods were intelligent marine predators.

The finding could change how scientists view Cretaceous oceans and the evolution of complex animal behavior.
