And then there's the overview of the Triassic.

然后接下来是三的概观。

The researchers believe the dinosaur lived during the Triassic Period.

研究人员认为这种恐龙生活在三期。

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

它导致了接下来的三期恐龙的崛起。

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

恐龙化石来自晚三世期，被称为“恐龙的黎明”。

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

这个代为三个期：三、侏罗和白垩。

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

恐龙最早出现在三期(距今约2.3亿年)的化石记录中。

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

在三期，所有的大陆都是盘古大陆的一。

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，游荡在三的沼泽中。

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

但直至三末期(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的期进化出来的。

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

事实上，大多数早三世的恐龙都处于濒临灭绝，包括肉食动物，比如凶猛的骡子，体型大小的腔骨龙。

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，人们都一直将三的终结归因于持续了60万年的大规模火山喷发。

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

三（2l000万年以前）和自垩（6500万年以前）别消灭了70%-75%的物种。

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

三期是一个非常重要的 5000 万年的演化期。

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

科学家说三晚期是第一批恐龙出现的黎明期。

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，出现在三期。

The world was pretty different during the late Triassic period.

三晚期的世界截然不同。

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

舞台是为 中生代的第一幕，三。

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

首先是 2.52 亿年前的二-三大灭绝 ——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， 三初期。
