Like, lycophytes were huge three hundred million years ago — literally.

比如，3 亿年前，石松植物是巨大的。

Horsetails and tree ferns grew to heights of fifty feet, club mosses to a hundred and thirty.

杉叶藻和桫椤长到l5米的高度，石松长到40米的高度。

In the walls were distinct impressions of fucoids and lycopodites.

墙上有明显的岩藻类和石松类的。

Some lycopods are still around today, like the low-lying, water-loving club mosses and quillworts.

一些石松类动物今天仍然存在，比如势低洼、喜的泥炭和金针茅。

He divided the mosses into six genera: Mnium, Hypnum, Polytrichum, Bryum, Sphagnum and Lycopodium — classifications that are useful today.

他把类分为六个：提灯、、金发、真、泥炭和石松，这些分类在今天仍然有用。

But it did just fine feeding on the seed ferns and lycophytes that were common during the Triassic, no teeth required.

但它以三叠纪时期常见的种子蕨类植物和石松类植物为食， 效果很好，不需要牙齿。

This is because scale trees were a type of plant called lycopods, which originated way back in the Silurian Period -- before seeds were even a thing!

这是因为鳞片树是一种叫做石松的植物，起源于志留纪时期——甚至在种子出现之前！

It was a lovely soft September afternoon — a day to lie under a Roman stone-pine, with one's eyes on the sky, and let the cosmic harmonies rush through one.

那是一个可爱而柔和的九月午后——一天躺在一棵罗马石松下，双眼望着天空，让宇宙的和谐在其中奔腾。

But lycopods were also the earliest vascular plants, which means they were the first plants to contain xylem, a special tissue that moves water and nutrients from the roots to the leaves.

但石松也是最早的维管植物，这意味着它们是最早含有木质部的植物，木质部是一种特殊的组织， 可以将分和养分从根部输送到叶子。
