兩棲魚龍

魚龍（百度）。

江大勇國際合作團隊在自然雜誌上發表了《中國下三疊統一短吻原始魚龍》，廣泛被認為填補了進化史上的一項空白。

Ichthyosaur fossil Cartorhynchus lenticarpus

The oldest known ichthyosaur lived 248 million years ago, and had characteristics such as flippers that may have allowed it to spend part of its life on land.

這是相關的報道：路透社，美網Huff Post，北大新聞網。也有說是”加州大學戴維斯分校研究人員領導“的，帶頭人乃Ryosuke Motani。他確實是文章的第一作者。搞不清楚。

土撥鼠

Vintana, seen in an artists's conception, is the second-largest mammal known from the age of dinosaurs, when most mammals were shrew-sized, behind only the badger-like Repenomamus from earlier in the Cretaceous Period.

據說新發現哺乳動物的土撥鼠和恐龍生活在一起，讓人大大開了眼界。這是加拿大廣播公司轉載路透社的報道。
