And their bacula can be 45 to 60 cm long.

它们的杆状骨可长达 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，在拉布雷亚发现的 400 多个杆状骨中，只有 8 个显示出受伤和恢复的迹象。

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.

拉布雷亚 (La Brea) 保存了大约 400 只恐狼的杆状骨——这使我们能够研究它们的大小和形状，以寻找它们交配行为的线索。

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，总的来说，Canis dirus 的杆骨断裂比你想象的要少得多——这表明这些狼很好地适应了性竞争激烈的生活方式。
