沥青坑

这些化石是拉布雷亚的沥青坑中发现的。这是已出土的一批极丰富的史前化石。

They were discovered in the tar pits of La Brea one of the richest finds of prehistoric fossils ever unearthed .

当研究人员把记录后的数据进行对比之后，他们很激动，因为数据表明吸引过来的群居食肉类动物比例，和发现在沥青坑里的的剑齿虎化石比例相匹配。

When they compared data , scientists were excited to find that the proportion of social predators attracted to the playbacks in Africa matched the proportion of Smilodon fossils found at the tar pits .

沥青坑里还有无数只鸟的尸体。

There are also endless numbers of birds in the tar as well .

立即掉进了沥青坑。

And were promptly bogged in the tar .
