LA Subway Excavation Uncovers Cache of Fossils

洛杉矶修地铁挖出大量史前生物化石

This huge collection of fossils was found underneath the street of Los Angeles. Underneath Wilshire Boulevard to be exact where workers are excavating an extension of the city subway.The fossils were saved thanks to strict California laws requiring paleontologists to be part of any extensive excavations.We're incredibly lucky that in California there are such strict mitigation so that there is requirement for there to be a paleontologist anytime you're digging in native soils.That way any fossil or artifacts that peaks out of that dirt is seen immediately and can be saved.These laws don't exist everywhere and so fossils are probably being lost all the time.

这个巨大的化石系列是在洛杉矶的街道下面发现的。确切地说,是工人们在挖掘威尔希尔大道城市地铁的延伸部分时发现的。由于加州法律对此很是严格,要求任何大规模的地下挖掘施工工作都要有古生物学者的参与,因而这些化石得以保存。我们非常幸运的是,在加利福尼亚有这么严格的减缓措施,任何原生土壤发掘工作,都需要有古生物学家在旁边。通过这种方式,不论是任何化石或手工艺品,只要在土里一露出来,就可以被保护起来。但这些法律并不是哪里都有,所以很多化石其实都没了。

Some of the most interesting discovery include a well preserved skull from the mammoth nicknamed Haydon.Here is the skull of a giant sloth and vertebrae and bones from giant saber-toothed cats and dire wolfs.Stopping work to dig up fossils can be expensive but LA official Dave Sottero says the paleontologists,the city and the excavation contractors generally figured out a way to get the fossils out of the ground and get the work done.

一些最有趣的发现中包括一个保存完好猛犸象头骨,绰号海顿。这是一个巨大的树懒的头骨,巨大剑齿虎的椎骨和惧狼的骨头。停止地铁施工去发掘化石价格不菲,但洛杉矶的官员戴夫·索特罗表示,古生物学家、市政府和挖掘承包商能够共同寻找解决办法,把化石从地下发掘出来的同时完成地铁施工。

I think in California we have the distinction is having the most stringent environmental rules anywhere in the country and possibly the world.So it behooves us to work very closely with the paleontologists to work very closely with the contractor and develop a set of best practices that will help us preserve the fossil record but still get our project done.

我认为在加州,我们最具特色的是拥有在全国乃至全世界的最最严格的环境法规。因此,我们有必要与古生物学家密切合作,与承包商密切合作,开发一套最佳实践方略,帮助我们保存化石的同时,仍能完成我们的项目。

The fossils provide a great look at this region 20, 30 and even 50 thousand years ago.Paleontologist Emily Lindsey says they can teach us about some issues we are dealing with today.Climate change which is something that caused great interests to people today and was also something that the world's experiencing when those of these large animals when they extinct and also how human activities can impact ecosystemsbecause around the time that human's arrived in the Americas is also around the time that we see most of those big animals that people are so excited about finding here extinct.

这些化石为我们提供了一个绝佳视角来观测这个地区在2万、3万甚至5万年前的情况。古生物学家艾米丽·林赛表示,它们可以教给我们一些如今人们棘手的问题。气候变化,这是如今人们最关注的,也是这个世界当下正在经受的,尤其是这些大型动物的灭绝人类活动从何种方面影响了生态系统。因为当人类定居美洲的时候,也是他们看到这些大型动物而感到兴奋的时刻,而如今它们却灭绝了。

The new fossils will go on display at the Natural History Museum of Los Angeles County.As for the new subway system, It will not be ready for the passengers until 2027.Plenty of time to find more fossils.

这些新化石将在洛杉矶自然历史博物馆展出。但由于新的地铁线路的缘故,化石要到2027年才能对游客开放展出。仍有足够的时间去寻找更多的化石。
