And then there's the overview of the Triassic.

然后接下来是三概观。

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

它导致了接下来三时期恐龙崛起。

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

恐龙化石来自晚三世时期，被称为“恐龙黎明”。

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

这个时代分为三个时期：三、侏罗和白垩。

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

恐龙最早出现在三时期(距约2.3亿年)化石记录中。

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2.01亿年)恐龙才取得地球霸主地位。

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

事实上，大多数早三世恐龙都处于濒临灭绝，包动物，比如凶猛骡子，体型大小腔骨龙。

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（2l000万年以前）和自垩（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.

三时期是一个非常重要 5000 万年演化时期。

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，出现在三时期。

The world was pretty different during the late Triassic period.

三晚期世界截然不同。

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

首先是 2.52 亿年前二-三大灭绝 ——也就是大灭绝。

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。

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

这是地球，距 2.5 亿年前， 三初期。

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

事实上，二齿兽类成为三最常见 陆地脊椎动物群。

252 million years ago, between the Permian and Triassic periods, the Earth's land masses gathered together into the single supercontinent Pangaea.

52亿年前， 在二和三时期之间，地球上陆地聚集 成 一个超级大盘古大陆。

The End-Triassic extinction saw the end of many of the pseudo sukian archosaurs that were dominant during the Triassic.

三末灭绝见证了许多在三期间占主导地位伪苏氏主龙终结。
