Was it more like primitive taxa like the crocodiles?

它是不是更像鳄鱼那样的原始类群?

But, you know, we're very hopeful that there may be other taxa that are actually hiding among all these bones.

但是，我们非常希望这里可能隐藏着其他的分类群化石。

Paleontologists have a word for these kinds of organisms: They call them Lazarus taxa.

古生物学家对这类生物有一个词：他们称它们为 Lazarus taxa。

They ultimately accumulated 307 entries for particular combinations of taxon and site.

他们最终为分类单元和站点的特定组合积累了 307 个条目。

The researchers examined 557 dinosaur taxa spanning seven continents and 136 million years across the Jurassic and Cretaceous.

研究人员检查了跨越七大洲、跨越侏罗纪和白垩纪 1.36 亿年的 557 个恐龙类群。

In consequence, many species are being described poorly in isolated publications, with no attempt to relate a new taxon to existing species and classifications.

结果，“不知名的出版物里对许多物种的描述都很蹩脚，没有人会努力把一个新的分类单元与现存的物种和分类联系起来”。

There are at least four more spectacularly preserved taxa of bats from just a bit later, around 47 million years ago, from the Messel Pit in Germany, a site we've talked about before.

不久之后，大约 4700 万年前，德国的 Messel Pit 至少有四种保存完好的蝙蝠分类群，这是我们之前讨论过的遗址。

But, aside from blowing our minds by re-appearing when we least expect it, Lazarus taxa give us a fascinating lesson in the limits of what the fossil record can really tell us.

但是，除了在我们最意想不到的时候重新出现让我们大吃一惊之外，拉撒路类群还给我们上了一堂有趣的课， 让我们了解化石记录真正能告诉我们的东西的局限性。

These taxa get the reputation for being well, dead because their remains suddenly disappear from the fossil record, making it look like they've vanished, even though they've stayed around, often for millions of years.

这些类群以健康、死亡而著称，因为它们的遗骸突然从化石记录中消失，看起来就像已经消失了，即使它们已经存在了数百万年。
