Sometime during the Cretaceous Period, 120 million years ago, a dinosaur wolfed down its last meal — a small mammal the size of a mouse. And it’s still there. A researcher with a sharp eye spotted the mammal’s foot preserved inside the guts of a fossilized Microraptor zhaoianus, a feathered therapod less than a meter long.
This new find adds a small mammal to their diet, suggesting these dinosaurs were opportunistic and not picky eaters,” Larsson, a coauthor of the study, said in a statement. “Knowing that Microraptor was a generalist carnivore puts a new perspective on how ancient ecosystems may have worked and a possible insight into the success of these small, feathered dinosaurs,” he explained.
