During the Triassic period, the continents were joined together into Pangea.

Around 250 million years ago, during the Triassic period, a class of reptiles called archosaurs split into two main groups.

The worst was 252m years ago between the Permian and Triassic periods, when 80% of marine species, as well as a lot of terrestrial ones, snuffed it.

最糟糕的是 2.52 亿年前的二叠纪和三叠纪时期，当时 80% 的海洋物种以及许多陆地物种都灭绝了。

But according to a new study published in the journal Nature Communications, we were wrong The study is about an archosauromorph called Dinocephalosaurus, a marine reptile dating back to the Triassic period.

但根据发表在《自然通讯》杂志上的一项新研究，我们错了。 这项研究是关于一种名为恐龙头龙的主龙类动物， 这是一种可追溯到三叠纪时期的海洋爬行动物。
