Cambrian predator might have eaten soft food

Anomalocaris, that fearsome predator of ancient seas, may have to return its title. A new analysis suggests that the monstrous shrimplike creature, which lived more than 500 million years ago, couldn’t handle crunchy food.

Researchers modeled the stresses that Anomalocaris jaws would have undergone while feeding on snacks as hard as lobster tails.
