An international team of researchers has found the first evidence of a dinosaur eating a mammal. In their paper published in Journal of Vertebrate Paleontology, the group describes their reexamination of a fossil found more than 20 years ago.
The work builds on the findings of a prior team who studied the fossil, Microraptor zhaoianus, back in 2000. It was found in the Jiufotang Formation in a western part of China. Back then, the research team dated it to approximately 120 million years ago, and noted that the fossil was missing most of its middle part but its rib cage was still intact.
