Fragments from mosses, algae, lichens and liverworts were trapped in the feathers.

他们发现其中残存着微量苔藓，藻类，地衣以及地钱片。

So while mosses, liverworts, and hornworts may be low to the ground, they are mighty.

因此，尽管苔藓、苔类植物和角苔类植物可能（长在）很低（地方），但它们很强大。

We're talking bryophytes and seedless vascular plants, the categories that include mosses and ferns, liverworts, and more.

我们说是苔藓植物和无籽维管植物，这类植物包括苔藓、蕨类、苔类等。

On land, signs of life were sparse -- there were bacteria, algae, early plants like liverworts, and possibly some of the first terrestrial arthropods.

在陆地上，生命迹象稀少——有细、藻类、地钱等早期植物，可能还有一些最早陆生节肢动物。

Creeping liverworts are here also in abundance, and several rare species of fungi, exceedingly small, and frail, and delicate, as if made only for beauty.

The general brown and purple of the ground, and the dead vegetation of the preceding year, give place to the green of mosses and liverworts and myriads of young leaves.

地面普遍呈棕色和紫色， 以及前一年枯死植被， 让位于绿色苔藓和苔藓以及无数嫩叶。

Paleobotanists are still debating what exactly the first type of land plant actually was, but they agree that it was small and moss-like, probably some kind of green algae or liverwort.

古植物家仍在争论第一种陆生植物到底是什么，但他们一致认为它很小， 像苔藓，可能是某种绿藻或地钱。

Despite their unfortunate name, liverworts do tons of cool, useful stuff, like helping rocks break down into soil, decomposing logs to return nutrients to the ground, and serving as materials for bird nests.

尽管它们名字很不幸，但地苔确实做了很多很酷、很有用事情，比如帮助岩石分解成土壤，分解木头把营养物质送回地面，还可以作为鸟巢材料。
