Okay, now the Mastodon is from the semi-late Jurassic period.

接下来这头乳齿象是来自侏罗纪中后期。

So the milk tooth falls out .

因此乳齿就会掉下来。

Scientists from UNSW and the University of Newcastle used a computer-based technique called Finite Element Analysis to test the bite force and feeding mechanics of the sabertooth, which preyed on giant bison, horse and perhaps mammoths and mastodons.

新南威尔斯大学和纽卡素大学的科学家们，使用名为「有限元素分析」的电脑科技，分析剑齿虎的咬力和进食力学，它通常猎捕长角野牛、马、也许还有长毛象和乳齿象。

Finding out more about mastodons and why they became extinct will help archeologists understand more about the people who lived thousands of years ago.

找出乳齿象的特性与他们绝灭的原因，将有助於考古学家更加了解数千年前人类的生活。

Archeologists say that for the people who lived then, mastodons were important, because people needed them for food.

考古学家表示，对生活在当时的人类来说，乳齿象是重要的食物来源。

There were dinosaurs and mastodons and dodo birds and such.

比如很多现在已经见不到的：恐龙、乳齿象、渡渡鸟等等。。。

As a boy, I was amazed by the huge fossils of mammoths and mastodons at the American Museum of Natural History in New York.

我小时候参观纽约的美国自然历史博物馆时，看到猛犸象和乳齿象的巨大化石十分吃惊。

Mastodons were large, furry animals over 3m tall that lived in North America thousands of years ago.

乳齿象是数千年前住在北美洲的巨型多毛动物，身高超过三公尺。

His chain suggested, not the beams, which it was its office to transport, but the mastodons and mammoth s which it might have served to harness

对手释放了精灵王，并且热血战歌+烈焰仪式后放出了一个相当大的净空繁殖地，跟着延缓了高大乳齿巨象。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
