BBC媒体英语 'Biggest dinosaur ever' discovered 史上最大恐龙化石出土

更新时间:2014/5/24 14:48:27 来源:本站原创 作者:佚名

古生物学家说,他们在阿根廷发现了迄今为止地球陆地上最大恐龙的骨骼化石。根据对其庞大的大腿骨做出的测量推算,这条恐龙体长 40米,身高 20米。

These creatures have yet to be given a name, but they belong to a group known as Titanosaurs. They had long necks and tails and are claimed by those who discovered them to have been the largest creatures ever to have walked the Earth. At full stretch they were the height of a seven-storey building and weighed more than ten full-grown elephants. Yet they were probably not fearsome, but mild-mannered vegetarians.

The giant dinosaurs lived 100 million years ago, in what is now Patagonia. Dr Bill Sellers, a palaeontologist at the University of Manchester, says it's a very exciting discovery:

"This is an amazing find because they’ve got so many dinosaurs there, I mean, this is seven individuals and these things are enormous! And actually it's really important because we don't know very much about these. We actually have very very few complete skeletons, and it looks like they've got quite a lot of bones here. So I think we'll be able to piece together what's a real animal rather than a sort of composite."

So far more than 200 bones have been found. The discovery should increase our understanding of how these magnificent creatures evolved.

According to palaeontologists, it weighed more than ten adult elephants.

2. What is the name of the place where the bones were found?
Patagonia.

3. Why is the finding important?
Because the scientists don't know much about these animals. The discovery of seven animals will allow them to piece together a complete skeleton and increase our understanding of how they evolved.

4. True or false? This species of dinosaur was a gentle creature, according to scientists.
