The earliest known eutherian mammal | Nature
Apr 25, 2002 — The skeleton of a eutherian (placental) mammal has been discovered from the Lower Cretaceous Yixian Formation of northeastern China. We estimate its age to be about 125 million years (Myr ...
An Early Cretaceous eutherian and the placental–marsupial ... - Nature
Jun 13, 2018 — This new fossil demonstrates that Sinodelphys is a eutherian, and that postcranial differences between Sinodelphys and the Jehol eutherian Eomaia—previously thought to indicate separate ...
The Sibling of All Placentals | Science - AAAS
Apr 25, 2002 — Eomaia's age and characteristics place it near the base of the placental-mammal family tree. Features of its teeth place it in Eutheria, the group that includes all the living placentals as well as extinct mammals that are closer to placentals than to marsupials.
Mother of All Marsupials | Science - AAAS
Now comes another record-breaker: the most ancestral marsupial known, in such good shape that even some of the fur is preserved. Described in today's issue of Science, the mouse-sized fossil will provide a wealth of information on how the earliest marsupials evolved.
