They settled on the mudflats of Chongming Island and Nanhui tidal flat near Shanghai.

他们定居在上海附近的崇明岛和南汇滩涂的泥滩上。

Then they likely died pretty quickly, and were washed onto the tidal flat where they were preserved.

然后它们可能很快就死了，并被冲到保存它们的滩涂上。

Well, back in the Miocene, Cerro Bellena was a beach, a tidal flat where dead and dying animals washed ashore over time.

好吧，回到中新世， Cerro Bellena 是一个海滩，一个潮滩，随着时间的推移， 死亡和垂死的动物被冲上岸。

And groups of unlucky marine mammals swam through the toxic blooms, died, and then floated toward the tidal flat, where storm surges lifted them onto the sand.

一群群不幸的海洋哺乳动物游过有毒的水华，死了， 然后漂向潮滩，风暴潮将它们卷到沙滩上。

And while most of the skeletons preserved at Cerro Ballena are whales, there are still other species, like seals, that should've been able to get back off the tidal flat and into the ocean.

虽然保存在 Cerro Ballena 的大部分骨骼都是鲸鱼，但还有其他物种， 如海豹，应该能够离开潮滩回到海洋。
