It was the age of weird fishes and plated sea lilies.

那是奇怪鱼和镀金海百合时。

Either way, the Paleozoic Era continued to be dominated by the crinoids and other echinoderms.

无论哪种方式，古生继续由海百合和其他棘皮动物统治。

The amateur fossil fiend spotted traces of ancient sea lilies, which only look flowery; they're actually invertebrates related to sea stars and urchins.

这位业余化石爱好者发现了古海百合踪迹，们看起来只是花香四溢；实际上是与海星和海胆有关无脊椎动物。

And it kinda looked like a flipped-over stalkless sea lily.

看起来有点像翻过来无柄海百合。

Modern starfishes move using their tube feet in a way that's similar to what crinoids do to waft food into their mouths.

现海星使用管脚移动，其方式类似于海百合将食物送入方式。

If anything, the eocrinoids and crinoids with stalks were moving away from the low-profile body plan of a starfish.

如果说有什么不同话，那就是带有茎海百合和海百合正在远离海星低调身体计划。

Paleontologists wonder whether the ability to move around might've helped starfishes fare better than the stationary crinoids did.

古生物学家想知道四处移动能力是否比静止海百合更能帮助海星生存。

Cantabrigiaster had the thick arms of a starfish but, like sea lilies, lacked small hard plates along the edges of its arms.

Cantabrigiaster 有海星一样粗手臂，但像海百合一样， 手臂边缘没有小硬板。

Sea levels were high, and the continents were surrounded by vast, shallow seas, full of exotic creatures like rugose corals, crinoids, and jawless fish.

海平面很高，大陆被广阔浅海包围，充满了奇异生物，如长皱纹珊瑚、海百合和无颌鱼。

So, the first starfish may have originated from a sea lily that faceplanted, putting its mouth down on the seafloor.

因此， 第一只海星可能起源于一种面朝下海百合，将巴放在海底。

It looks like some of the crinoids might've taken a different approach to feeding - instead of staying face-up suspension feeders, they went face-down.

看起来有些海百合可能采取了不同进食方式——们不再是面朝上悬浮式喂食器，而是面朝下。

But we still need more fossil evidence to help us figure out whether Cantabrigiaster really was a transitional animal between crinoids and sea stars or not.

但是我们仍然需要更多化石证据来帮助我们弄清楚 Cantabrigiaster 是否真是海百合和海星之间过渡动​​物。

Crinoids became the most abundant echinoderms of the Ordovician, and some were the ancestors of today's stalkless feather stars and stalked sea lilies.

海百合成为奥陶纪最丰富棘皮动物，有些是今天无柄羽星和有柄海百合祖先。

Including the similar-looking and closely related group - the crinoids, also called sea lilies - which showed up and diversified into many species with different suspension-feeding body types.

包括外观相似且密切相关群体——海百合，也称为海百合——们出现并多样化为许多具有不同悬浮喂养体型物种。

And crinoids are still around, too, but their species number in the 600s, in contrast to the 6000 known species that've lived throughout Earth's history.

海百合也仍然存在，但们物种数量只有 600 种，而地球历史上已知物种数量为 6000 种。

But starfishes and their skinny-armed cousins called the brittle stars made it through, along with a few crinoids, sea cucumbers, and sea urchins – the groups we still see today.

但是海星和们被称为海蛇尾瘦臂表亲以及一些海百合、海参和海胆——这些我们今天仍然能看到群体——成功了。

I explain it on two grounds, I replied. In the first place, because vertical currents, which are caused by differences in the water's salinity and density, can produce enough motion to sustain the rudimentary lifestyles of sea lilies and starfish.

我用两个理由来解释，我回答，第一，因为那些上下垂直往来水流，由海水不同咸度和不同密度决定，发生一种运动，足以维持海百合和海星一类原始基本生活。

So, as odd as the starfish body plan seems, something about it was successful -- from their ancient bilateral ancestors, to the radial crinoids with their upward-facing arms, to the predatory, downward-facing starfish.

因此， 尽管海星身体计划看起来很奇怪，但某些方面是成功——从们古老双侧祖先，到手臂朝上放射状海百合，再到捕食性、面朝下海星。
