Summary
An international team of paleontologists has discovered one of the oldest and smallest mammals in China, according to Dr. Zhexi Luo of the Carnegie Museum of Natural History.
The small mammal, christened Hadrocodium wui, weighed only two grams and grew to a length of 32 millimeters, but may turn out to be an important character in the early evolution of mammals. Living 195 million years ago during the Jurassic, Hadrocodium possessed several key mammalian traits that may give insights into how mammals diversified.
"Mammals differ from non-mammalian vertebrates by possessing a very large brain and an advanced ear structure. It has been a challenge for scientists to trace the origin of these important mammalian features in the fossil record," Luo et al. 2001; Carnegie-IVPP collaboration.
