The supercontinents of Laurasia and Gondwanaland fractured, forming the lands that man would inhabit millions of years later.

劳亚和冈瓦纳两个超级大陆分裂后，形成了人类在亿万年后居住的大陆。

America and Eurasia, together known as Laurasia, collided with Gondwana.

北美和欧亚大陆（统称为劳亚大陆） 与冈瓦纳大陆相撞。

These two small super continents are called Laurasia and Gondwana.

这两个小型超级大陆被称为劳亚大陆和冈瓦纳大陆。

Eventually, Gondwana and Laurasia broke apart into the smaller continents that we know today.

最终，冈瓦纳大陆和劳亚大陆分裂成我们今天所知的较小大陆。

Laurasia was made up of present-day Asia, Europe, and North America, while Gondwana was composed of South America, Australia, Africa, Antarctica, Madagascar, and India.

劳亚大陆由今天的亚洲、欧洲和北美洲组成，而冈瓦纳大陆由南美洲、澳大利亚、非洲、南极洲、马达加斯加和印度组成。

Finally, in the Late Cretaceous, the continued break up of both Laurasia and Gondwana led to a similar, further break up of the different dinosaur groups.

最后，在晚白垩世，劳亚大陆和冈瓦纳大陆的持续分裂导致了不同恐龙群的类似进一步分裂。
