　　leading paleontologists to speculate that this dance would have been very simple.

　　因此也很原始这让古生物学家们猜测这种舞蹈应该非常简单。

　　Certainly, given the brain size of something like Majungasaurus which has a relatively² primitive brain,当然要是像玛君龙那样只有比较原始的大脑，

　　we would expect them to have the kinds of primitive, very ritualized,我们估计它们的求偶仪式会是很原始、很模式化，courtship rituals that we see in lizards³ and crocodiles today,就像现代的蜥蜴和鳄鱼一样，
