在加拿大北極地區發現古代犀牛化石

Ancient Rhino Fossil Discovered in the Canadian Arctic

在一項顯著的古生物學突破中,科學家鑑定出一個名為 Epiaceratherium itjilik 的新古犀牛物種,其名在因紐特語中意為「霜凍」。

In a remarkable paleobiological breakthrough, scientists have identified a new, ancient rhinoceros species named Epiaceratherium itjilik, meaning "frosty" in Inuktitut.

此標本是在德文島的霍頓隕石坑(ㄏㄨㄛˋㄉㄨㄣˋㄩㄣˋㄕˊㄎㄥ)中發現的,是有史以來發現的最北端犀牛化石。

Discovered in the Haughton Crater on Devon Island, this specimen is the northernmost rhino fossil ever found.

這種小型無角犀牛生活在約 2300 萬年前的早中新世,居住在溫帶森林地景中,與現代的北極形成鮮明對比。

Living roughly 23 million years ago during the Early Miocene, this small, hornless rhino inhabited a temperate, forested landscape, a stark contrast to the modern Arctic.

此外,研究人員利用先進的古代蛋白質分析將這種生物與歐洲物種聯繫起來。

It suggests that the North Atlantic Land Bridge remained a viable route between Europe and North America much longer than previously assumed.

作為獨特的「時間膠囊」的霍頓隕石坑,很可能還保存著更多史前生命的證據。

Furthermore, researchers used advanced ancient protein analysis to link this creature to European species.
