One hundred million years later, the warm, shallow seas were packed with tiny plants and animals — essentially, hors d'oeuvres for a plethora of bigger creatures like trilobites, conodonts, brachiopods, and corals.

一千万年之后，温暖的浅海充满了微小的植物动物——基大量大型生物的开胃，如同三叶虫，牙形虫，腕珊瑚。

We've got little seashells and things like bivalves and brachypods.

我们有小的海贝壳双壳、腕等东西。

Scientists began to realize that this pattern  of change was also replicated in other small, specialized marine creatures of the Silurian, like  the eel-like conodonts and clam-like brachiopods.

科学家开始意识到，这种变化模式也在志留纪其他小型特化的海洋生物中重现，比如鳗鱼状的牙形石蛤蜊状的腕。
