What did ancient crocodiles eat? Study says as much as a snout can grab

To study the diet of ancient crocodiles, two researchers combined mathematical analyses of the animals' shapes, surveys of modern crocodiles' diet, modeling methods for reconstructing the diet of fossil groups, and forensic-style interpretations of damaged bones from the distant past.
