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。
Most probably so did Balaur as well, and this is the main challenge coming out of its discovery - understanding how it actually lived.
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。
