Paleontologists say they have identified foot of mouse-sized mammal in fossilised rib cage of predatory microraptor
It may have been a pressing fear for the fictional characters in the 1993 film Jurassic Park, but scientists believe they have uncovered the first known incident of a mammal being eaten by a dinosaur.
However, the fossils from 120m years ago are not of a human ancestor, but instead the foot of an animal inside the ribcage of a small feathered dinosaur, known as a microraptor.
