The dinosaur fossils are from the Late Triassic period, called the “dawn of the dinosaurs.”

化石来自晚叠世时期，被称“黎明”。

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

最早出现在叠纪时期(距今约2.3亿年)化石记录中。

It led to the rise of dinosaurs during the following Triassic Period.

它导致了接下来叠纪时期崛起。

And then there's the overview of the Triassic.

然后接下来是叠纪概观。

This little creature spends its days splashing in Late Triassic swamps with a host of other reptiles.

这种小生物与其它爬行动物一起，游荡在叠纪沼泽中。

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

但直至叠纪末期(距今2.01亿年)才取得地球霸主地位。

The researchers believe the dinosaur lived during the Triassic Period.

研究人这种生活在叠纪时期。

It was thunderingly unlikely that this unique triassic animal could have evolved on three separate occasions.

这种独特叠纪动物在个不同时期进化，这几乎是不可能。

In fact, most early Triassic dinosaurs were on the shrimpy side, including predators like the fierce, mule-sized Coelophysis.

事实上，大多数早叠世都处于濒临灭绝，包括肉食动物，比如凶猛骡子，体型大小腔骨。

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

最早和其他动物是在地球上一个被称叠纪时期进化出来。

The era is divided into three periods: Triassic, Jurassic, and Cretaceous.

这个时代分个时期：叠纪、侏罗纪和白垩纪。

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

在叠纪时期，所有大陆都是盘古大陆一部分。

And then after the Triassic, we really get into kind of the sweet spot of the dinosaur age.

然后，在叠纪之后，我们真正进入了时代黄金时期。

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

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

The small reptile would have lived in the Triassic Period on land which is today southern Brazil.

这种小型爬行动物应该生活在叠纪时期陆地上，也就是今天巴西南部。

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，人们都一直将叠纪终结归因于持续了60万年大规模火山喷发。

The world was pretty different during the late Triassic period.

叠纪晚期世界截然不同。

One of the oldest pterosaurs currently known is Eudimorphodon, from the late Triassic of Europe.

目前已知最古老翼之一是尤迪莫福顿，它来自欧洲晚叠纪。

This right here would be the permian triassic extinction.

这便是二叠纪-叠纪大灭绝事件。

Triassic before that, but that's more the rise of the dinosaurs.

在那之前叠纪，不过那主要是崛起时期。
