东田纳西州立大学的研究人员 发现了一个巨型飞松鼠的化石 大约相当于一只家猫的大小 追溯到500万年前 Researchers at East Tennessee State University have uncovered a fossil of a giant flying squirrel, about the size of a house cat, dating back 5 million years. 松鼠很可能在气候变暖时从亚洲迁移,并有人居住着古老的阿巴拉契亚森林,直到冰河时代将其赶向南方,导致其灭绝。 The squirrel likely migrated from Asia during a warmer climate and inhabited ancient Appalachian forests until Ice Ages drove it south, leading to its extinction. 该发现在《哺乳动物进化杂志》中详述, 也揭示了这个网站 产生了一个大型顶级掠食犬物种的化石。 The discovery, detailed in the "Journal of Mammalian Evolution," also reveals the site yielded fossils of a large, apex predator dog species.
