雄浑壮阔的中国北方草原,曾是远古马类繁衍、辐射的中心,也是现代马生息,驰骋的乐园。马的演化历史可追溯到距今5000多万年前的始新世早期,最初个体很小,后经漫长的演化过程,才成为现在魁伟的体魄。迄今为止,内蒙古发现最早的马化石是距今1000万年前中新世中期的戈壁安琪马,其个体接近现在的驴,前后脚均为粗壮的三趾型,生活于湿热的森林草原。到距令800万年争500万年前的晚中新世,内蒙古有了较大型的三趾齐氏中华马、环齿三趾马、蒙古三趾马等。更新世早期,北方出现单趾型的真马类,即前后脚
The magnificent grassland in the north of China was once the center of ancient horse breeds and radiations and also a paradise for modern life and gallop. The horse’s evolutionary history dates back to the early Eocene ages more than 50 million years ago. Initially, the individual was very small. After a long evolution, the horse became the burly body now. So far, the earliest horse fossil found in Inner Mongolia is the Gobi An Qi Ma, dating back to the middle of the Miocene 10 million years ago. Its individual is close to the present donkey. Both feet are thick, three-toe-type feet and live in hot and humid forest grasslands. In the late Miocene 5 million years ago from the order of 8 million years in Inner Mongolia, there were larger three-toed Qihwa Chinese horses, ring-shaped three-toed horses and Mongolian three-toed horses in Inner Mongolia. In the early Pleistocene, the northern one-toed type of real horse, that is, front and rear feet
