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，在拉布雷亚发现 400 多个杆状骨中，只有 8 个受伤恢复。

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 杆骨断裂比你想要少得多——这表明这些狼很好地适应了性竞争激烈生活方式。
