科學家在北極發現古代犀牛化石
Scientists Discover Ancient Rhinoceros Fossil in the Arctic
區分在加拿大發現的中新世（ㄓㄨㄥ ㄒㄧㄣ ㄕˋ）時期的「化石骨骼遺跡」與在西伯利亞發現的更新世（ㄍㄥ ㄒㄧㄣ ㄕˋ）時期的「木乃伊屍體」非常重要。
It is important to distinguish between the 'fossilized skeletal remains' of the Miocene era found in Canada and the 'mummified carcasses' of the Pleistocene epoch discovered in Siberia.
在加拿大，研究人員鑑定出了小古犀（Epiaceratherium itjilik），這是一種生活在2300萬年前溫帶森林中、無角的小型犀牛。
In Canada, researchers identified Epiaceratherium itjilik, a small, hornless rhino that lived 23 million years ago in temperate forests.
這項發現證實了早期犀牛曾利用陸橋往返於歐洲和北美之間。
This discovery proves that early rhinos used a land bridge to travel between Europe and North America.
相反地，西伯利亞的發現則與披毛犀（ㄊㄧ ㄇㄠˊ ㄒㄧ）有關，這是一種適應冰河時期嚴酷「猛獁象草原（ㄇㄥˇ ㄇㄚˇ ㄒㄧㄤˋ ㄘㄠˇ ㄩㄢˊ）」的生物。
Conversely, the Siberian discoveries involve the woolly rhinoceros, a creature adapted to the harsh 'mammoth steppe' of the Ice Age.
由於這些遺跡保存於永久凍土層中，因此被發現時為軟組織木乃伊，而非僅是骨骼。
Because these remains were preserved in permafrost, they are found as soft-tissue mummies rather than just bones.
雖然加拿大的化石改變了我們對遷徙模式的理解，但西伯利亞的木乃伊使科學家能夠研究內部的解剖結構和適應特徵，例如神秘的脂肪肩峰。
While the Canadian fossils change our understanding of migration patterns, the Siberian mummies allow scientists to study internal anatomy and adaptations, such as a mysterious fatty shoulder hump.
