And then there's the overview of the Triassic.

然后接下来是三叠纪概观。

The researchers believe the dinosaur lived during the Triassic Period.

研究人员认为这种恐生活在三叠纪期。

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

它导致了接下来三叠纪期恐起。

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

恐化石来自晚三叠世期，被称为“恐黎明”。

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

这个代分为三个期：三叠纪、侏罗纪和白垩纪。

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

恐最早出现在三叠纪期(距今约2.3亿年)化石记录中。

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

在三叠纪期，所有大陆都是盘古大陆一部分。

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，游荡在三叠纪沼泽中。

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.

最早恐和其他动物是在地球上一个被称为三叠纪期进化出来。

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

事实上，大多数早三叠世恐都处于濒临灭绝，包括肉食动物，比如凶猛骡子，体型大小腔骨。

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终结归因于持续了60万年大规模火山喷发。

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%物种。

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

三叠纪期是一个非常重要 5000 万年演化期。

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

科学家说三叠纪晚期是第一批恐出现黎明期。

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

专家认为恐和那边恐一样，出现在三叠纪期。

The world was pretty different during the late Triassic period.

三叠纪晚期世界截然不同。

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

舞台是为 中生代第一幕，三叠纪。

First was the Permian-Triassic extinction 252 million years ago -- aka the Great Dying.

首先是 2.52 亿年前二叠纪-三叠纪大灭绝 ——也就是大灭绝。

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。
