当古生物学家们研究这些齿痕时，他们使用高倍显微镜来更深入地了解这些证据。

　　What they found were tell-tale serrations meaning the culprit who chewed these bones had serrated teeth and jaws powerful enough to cut the bone.

　　他们发现了泄露秘密的锯齿痕迹，这表明咬到这些骨头的肇事者拥有锯齿状牙齿，而且颌部有力能够切开骨头。

　　Since no other dinosaur on Madagascar had been found with teeth this large, pretty much ruled out all of the predators.

　　因为在马达加斯加没有其它恐龙有这么大的牙齿，这就基本排除了所有其它掠食者。

　　Measuring the width, length and serrated edges of the teeth and calculating the spacing between the teeth and the jaw,通过测量这些牙齿的宽度长度和锯齿状边缘并且计算牙齿和颌骨间的间隙，scientists were able to determine that the teeth and jaws of Majungasaurus match the gash marks in the bone almost perfectly.

　　科学家们能够确定玛君龙的牙齿和颌部与骨头上沟痕的匹配近乎完美。

　　Majungasaurus has serrated teeth. Each one of those little serrations is call a denticle.

　　玛君龙有锯齿状的牙齿。每一个这样小的锯齿叫做小齿。

　　The denticle marks found in the bones were spaced about 0.48 millimeters apart.

　　在被发现的骨头上的小齿痕迹之间的间隙大概是0.48毫米。

　　In studying Majungasaurus teeth, paleontologists just discovered that they had an average spacing for about 0.5 millimeters.

　　通过研究玛君龙牙齿古生物学家们也发现了这些小齿间隙的均值是大概0.5毫米。

　　That's nearly identical to those left on the bone.

　　这和骨头上的痕迹几乎一模一样。

　　What began as a routine dig was looking to change history.

　　一次例行的挖掘看来会改变历史。

　　Two Majungasaurus in a fight to the death.

　　两头玛君龙进行了生死搏斗。

　　These bite marks were not just the result of the fight.

　　这些咬痕不只是搏斗的结果。

　　One Majungasaurus appears to have eaten the other.

　　看起来一头玛君龙吃了另一头。

　　We know that this isn't just fighting, not just bite marks on the snort, for example.

　　我们知道这不仅是打斗不像是在鼻子上留下的咬痕。

　　These are tooth marks that are on the inside bones of the body,在其身体内部的骨头上也有齿痕，

　　on leg bones and back bones and ribs that you couldn't get to from the outside.

　　包括腿骨、脊柱和肋骨这样的地方从外面咬不到。

　　So clearly, at least on occasion, Majungasaurus ate other Majungasaurus.

　　所以很明显，起码有一次一头玛君龙吃了另一头。

　　With what appeared to be proof that they were looking at cannibalism,在看来好像是同类相食的证据之外，

　　other evidence was needed to piece together why these creatures might have fought this battle.

　　仍然需要其它证据来弄清楚为什么它们要进行这场搏斗。
