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，显示有人常年住在格伯托。他的团队收集，这是鱼类内的骨构造。

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

就像牙齿的，会呈小小的环圈生长，每一季加上新的一圈。

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

最外侧的一圈表示一只鱼遭捕捉的时间。在格伯托的贝冢找的，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.

在每个类似呼拉圈的小管子里，有一些叫做的小头，这些会在底部滚动，就像呼拉圈底部的弹珠一样。
