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.

塞雷诺还发现了别证据，显示有人常年住在格。团队收集到耳石，这是鱼类内耳骨质构造。

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

就像牙齿层层釉质，耳石会呈圈生长，每一季加上新一圈。

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

最外侧一圈表示一只鱼遭到捕捉时间。在格贝冢找到耳石，显示这里全年都在捕鱼。

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.

在每个类似呼拉圈管子里，有一些叫做耳石石头，这些耳石会在底部滚动，就像呼拉圈底部弹珠一样。
