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”。

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。

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。

And then there's the overview of the Triassic.

然接下来是三的概观。

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，游荡在三的沼泽中。

Wegener thought that there had actually been only one continent for most of geologic time and that the giant continent had fragmented in the late Triassic Period.

魏格纳认为，在地质期的大部分间里，实际上只有一块大陆，而这块巨大的大陆在晚三期分裂了。

And then we go into the Triassic period, a really hard time for life on Earth, the world is recovering from this Great Dying event.

然进入三，这是地球生命的艰难期，世界正在从“大灭绝”事件中恢复。

Another mass extinction at the end of the Triassic about 201 million years ago killed off many early competitors to the dinosaurs.

另一次大规模灭绝发生在大约2.01亿年前的三末期，导致恐龙的许多早期竞争者死亡。

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%的物种。

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。

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

这个代分为三个期：三、侏罗和白垩。

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。

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。

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

这种独特的三动物在三个不同的期进化，这几乎是不可能的。

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

然，在三之，真正进入了恐龙代的黄金期。

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。

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 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三期的陆地上，也就是今天的巴西南部。

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部分。

But certain Jurassic and Triassic forms are now commonly admitted to be teleostean; and even some palaeozoic forms have thus been classed by one high authority.

但是某些侏罗和三的形式现在普遍被认为是硬骨动物；甚至一些古生代类型也因此被一位权威机构分类。
