And then there's the overview of the Triassic.

然后接下来是三叠纪的概观。

The researchers believe the dinosaur lived during the Triassic Period.

研究人员认为这种恐龙生活在三叠纪时期。

During the Triassic Period, all continents were part of a single land mass called Pangea.

Dinosaurs first appear in the fossil record during the Triassic period, some 230m years ago.

恐龙最早出现在三叠纪时期(距今约2.3亿年)的化石记录中。

They do not take over, though, until the end of the Triassic, 201m years ago.

但直至三叠纪末期(距今2.01亿年)恐龙才取得地球霸主地位。

The first dinosaurs and these other animals evolved during a time on earth called the Triassic Period.

最早的恐龙和其他动物是在地球上一个被称为三叠纪的时期进化出来的。

The Triassic (210 million years ago) and Cretaceous (65 million years) each wiped out 70 to 75 percent of species.

三叠纪（2l000万年以前）和自垩纪（6500万年以前）分别消灭了70%-75%的物种。

Until now, the end of the Triassic has been blamed on massive volcanic eruptions that went on for 600,000 years.

直到现在，人们都一直将三叠纪的终结归因于持续了60万年的大规模火山喷发。

Another mass extinction at the end of the Triassic about 201 million years ago killed off many early competitors to the dinosaurs.

另一次大规模灭绝发生在大约2.01亿年前的三叠纪末期，导致恐龙的许多早期竞争者死亡。

The Triassic period was an incredibly important 50 million years of evolution.

三叠纪时期是一个非常重要的 5000 万年的演化时期。

But afterward, in the Triassic, some amphibians still held on.

但后来，在三叠纪，一些两栖动物仍然坚持了下来。

Experts think dinosaurs, like those over there, appeared during the Triassic.

专家认为恐龙和那边的恐龙一样，出现在三叠纪时期。

The stage was set for the first act of the Mesozoic, the Triassic Period.

舞台是为 中生代的第一幕，三叠纪。

This is Earth, 250 million years ago, at the beginning of the Triassic Period.

这是地球，距今 2.5 亿年前， 三叠纪初期。

In fact, the dicynodonts became the most common group of land vertebrates during the Triassic.

事实上，二齿兽类成为三叠纪最常见 的陆地脊椎动物群。

Pangea did not begin to break apart until the end of the Triassic period.

直到三叠纪末期，盘古大陆才开始分裂。

Over the vast epochs of the Mesozoic era--the Triassic, Jurassic, and Cretaceous periods--dinosaurs evolved into myriad forms.

在中生代的漫长时期——三叠纪、侏罗纪和白垩纪——恐龙进化成了无数的形态。

Dinofluff - which experts technically call protofeathers - probably goes all the way back to the Triassic.

恐龙绒毛——专家们在技术上称之为原羽毛——可能一直追溯到三叠纪。

Remember, that early in the Triassic, dinosaur morphs were uncommon.

请记住，在三叠纪早期，恐龙变体并不常见。

There weren't many dinosaurs around at all during the early part of the Triassic.

在三叠纪早期，周围根本没有多少恐龙。
