And then there's the overview of the Triassic.

然后接下是叠纪概观。

The researchers believe the dinosaur lived during the Triassic Period.

研究人员认为这种恐龙生活在叠纪时期。

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

它导致了接下叠纪时期恐龙崛起。

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

恐龙化自晚叠世时期，被称为“恐龙黎明”。

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

在叠纪时期，所有陆都是盘古陆一部分。

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

这个时代分为个时期：叠纪、侏罗纪和白垩纪。

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

恐龙最早出现在叠纪时期(距今约2.3亿年)化中。

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)恐龙才取得地球霸主地位。

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。

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。

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

最早恐龙和其他动物是在地球上一个被称为叠纪时期进化出。

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

事实上，多数早叠世恐龙都处于濒临灭绝，包括肉食动物，比如凶猛骡子，体型小腔骨龙。

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，我们真正进入了恐龙时代黄金时期。

The world was pretty different during the late Triassic period.

叠纪晚期世界截然不同。

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。

Turtles first evolved back in the Triassic.

海龟最早是在叠纪时期进化而。

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60万年规模火山喷发。

Scientists say the late Triassic period was the dawn of the first dinosaurs.

科学家说叠纪晚期是第一批恐龙出现黎明时期。

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

专家认为恐龙和那边恐龙一样，出现在叠纪时期。

This is an echo of what life was like back in the Triassic.

这是叠纪时期生活历史回声。
