And their bacula can be 45 to 60 cm long.

它们杆状骨可长达 45 至 60 厘米。

And, sure enough, of the 400-some bacula found at La Brea, only 8 show signs of injury and rehealing.

而且，果然，在拉发现 400 杆状骨中，只有 8 显示出受伤恢复迹象。

And about 400 bacula of Dire wolves have been preserved at La Brea – which has allowed us to study their size and shape for clues into their mating behavior.

拉 (La Brea) 保存了大约 400 只恐狼杆状骨——这使我们能够研究它们大小形状，以寻找它们交配行为线索。

But the point is, overall, Canis dirus had far fewer broken bacula than you'd expect -- evidence that these wolves were well-adapted to a lifestyle where sexual competition was fierce.

但关键是，总来说，Canis dirus 杆骨断裂比你想象要少得——这表明这些狼很好地适应了性竞争激烈生活方式。
