An international team of paleontologists has discovered a new species of mammal that lived in China's Liaoning Province 123 million years ago. This remarkably well preserved fossil, as reported in the Oct. 9 issue of Science, offers important insight into how the mammalian middle ear evolved. Such exquisite dinosaur-age mammals provide evidence of how developmental mechanisms have impacted the evolution of the earliest mammals.Full Story
