Paleontologists Discover New Mammal
An artist's representation of Yanoconodon allini, a 125 million-year-old mammal that lived during the Mesozoic Era in what is now the Hebei Province in China.
The fossil discovery, which was made by a National Science Foundation-funded international team of researchers, provides first-hand evidence of early evolution of the mammalian middle ear--one of the most important features for all modern mammals.
