“We're used to thinking of the Age of Dinosaurs as a time when dinosaurs ruled the world, and the tiny mammals cowered in the shadows." “This turns the old story on its head,” Brusatte said. But the new find also suggests that mammals may have actually preyed on dinosaurs several times their size, and didn't just scavenge ones that were already dead, Mallon said. That mammals ate dinosaur meat had been proposed before: another fossil showed a mammal died with dinosaur remains in its gut. “I've never seen a fossil like this before," Mallon said. The mammal is perched on the dinosaur, its paws gripping the reptile's jaw and a hind limb while its teeth plunge into the ribcage. The fossil, described Tuesday in the journal Scientific Reports, shows two creatures from around 125 million years ago, during the Cretaceous period.Įven though the mammal is much smaller, researchers think it was attacking the dinosaur when they both got caught in the volcanic flow, said study author Jordan Mallon, a paleobiologist at the Canadian Museum of Nature. “It does seem like this is a prehistoric hunt, captured in stone, like a freeze frame,” University of Edinburgh paleontologist Steve Brusatte, who was not involved with the study, said in an email. The find comes from a site known as “China's Pompeii,” where mud and debris from long-ago volcanoes buried creatures in their tracks. The fossil shows a badgerlike creature chomping down on a small, beaked dinosaur, their skeletons intertwined. New York, Jul 18 (AP) An unusual find in China suggests some early mammals may have hunted dinosaur for dinner.
