That means that our record of Balaur is restricted to the very end of the Cretaceous.

这意味着我们有关巴拉乌尔龙的记录限定于白垩纪的晚期的晚期。

But, the bottomline is - Balaur being so closely related to animals from Asia and North America suggests interchanges with that area.

但是，至少我们知道——巴拉乌尔龙和亚洲和北美的动物关系如此密切，表明这些区域之间有物种交换。

巴拉乌尔龙很可能也是这样，而这就是这一发现之后所带来的主要挑战——理解它实际的生活方式。
