Sereno has found other evidence that implies people lived year-round at Gobero. His teams have collected otoliths, the bony structures from the inner ears of fish.

塞雷诺还发现了别的证据，显示有人常年住托。他的团队收集到耳石，这是鱼类内耳的骨质构造。

Like layers of enamel in teeth, otoliths grow in tiny rings, adding a new one each season.

就像牙齿的层层釉质，耳石会呈小小的长，每一季加上新的一。

The outermost ring suggests when a fish was caught. The otoliths found in Gobero's middens indicate the fish were caught throughout the year.

最外侧的一表示一只鱼遭到捕捉的时间。托的贝冢找到的耳石，显示这里全年都捕鱼。

And inside of each of those little hula hoop-like tubes, there are little stones called otoliths, okay, you heard that word earlier, that roll around on the bottom, just like marbles at the bottom of a hula hoop.

每个类似呼拉的小管子里，有一些叫做耳石的小石头，这些耳石会底部滚动，就像呼拉底部的弹珠一样。
