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

那是奇鱼类和铠装海百合的时代。

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代海百合的踪迹，它们看起来只是花香四溢；实际上是与海星和海胆有关的无脊椎动物。

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

看起来有点像翻过来的无茎海百合。

Heading into the Ordovician Period, around 485 million years ago, eocrinoids diversified into thousands of forms.

进入奥陶纪时期， 大约4.85，早期海百合分化出了数千种形态。

Species like conodonts, ammonoids, crinoids and green algae suffered particularly  high extinction rates during the CPE, as did reef builders.

在卡尼期洪积事件期间， 诸如牙形石、菊石、海百合和绿藻等物种遭受了特别高的灭绝，礁建造者亦未能幸免。

Some eocrinoids, like Gogia, developed stem-like stalks that raised their arms higher into the water column, further from the sediment.

一些早期海百合， 如戈吉亚，进化出了类似茎的柄， 将它们的臂抬高到水柱中，远离沉积物。

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

无论如何，古生代依然由海百合和其他棘皮动物主导。

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

现代海星利用它们的管足移动，这种方式与海百合将食物扇入嘴中的方式类似。

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

如果有的话，带茎的早期海百合和海百合正逐渐远离海星那种低矮的身体结构。

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

古生物学家好奇移动能力是否帮助海星比固定不动的海百合更好地生存下来。

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

海百合成为了奥陶纪最丰富的棘皮动物，其中一些是今天无茎羽状海百合和有茎海百合的祖先。

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

Cantabrigiaster 有海星一样粗的手臂，但像海百合一样， 手臂边缘没有小的硬板。

Eocrinoids first appeared in the fossil record roughly 517 million years ago.

早期海百合最早出现在大约5.17的化石记录中。

One of these groups, called eocrinoids, had a bunch of spaghetti-like feeding arms spread out around an upward-facing mouth.

这些群体中的一种被称为早期海百合，它们有一堆类似意大利面的触手围绕着一个朝上的嘴巴。

Early Cambrian eocrinoids stuck lightly to sediment or just rested on it while suspension-feeding.

寒武纪早期的早期海百合轻盈地附着在沉积物上，或者只是躺在上面进行悬垂摄食。

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的海百合，将嘴巴放在海底。

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的进食方式——它们不再是面朝上的悬浮式喂食器，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.

但我们仍然需要更多的化石证据来帮助我们确定坎特布里海星是否真的是从海百合向海星过渡的动物。

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，各大洲周围都是广阔的浅海，里面充满了奇异的生物，如皱纹、海百合和无颌鱼。

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.

以及外形相似且亲缘关系密切的群体——早期海百合，它们出现了并分化成许多具有不同悬垂式进食身体结构的物种。
