These preserved footprints, are a type of ichnofossil.

这些保存下来的脚印，是一种遗迹化石。

These are collectively called trace fossils, or more formally, ichnofossils.

这些统称为痕迹化石，或更正式地说，遗迹化石。

Ichnofossils are any track or trail, left behind by an animal.

遗迹化石是动物留下的任何足迹或小径。

But with ichnofossils, it's a lot trickier.

但是对于遗迹化石，它要棘手得多。

But these ichnofossils also tell us something important about what these animals were moving across.

但这些遗迹化石也告诉我们一些关于这些动物迁徙经过的重要信息。

They're also called ichnofossils, and they can give us important clues about things like ancient environments and animal behaviors.

它们也被称为遗迹化石，它们可以为我们提供有关古代环境和动物行为等方面的重要线索。

So instead of saying an ichnofossil is a T. rex footprint, for example, the trace is given its own two-part name, with an ichnogenus and an ichnospecies.

因此，例如，不是说化石化石是霸王龙足迹，而是给足迹赋予了它自己的两部分名称，一个是 ichnogenus 和一个 ichnospecies。

Ichnofossils can be a gateway into individual moments in the distant past, a snapshot of the Cretaceous - even if that picture is a little blurred by the passage of time.

遗迹化石可以成为通往遥远过去的个人时刻的门户，是白垩纪的快照——即使随着时间的流逝， 这张照片有点模糊。
