Dr. Tao Deng from Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, and his team report a well-preserved skeleton of a 4.6 million-year-old three-toed horse (Hipparion zandaense) from the Zanda Basin, southwestern Tibet. Morphological features indicate that the Zanda horse was a cursorial horse that lived in alpine steppe habitats.
