Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which ...

In this activity, your class will use images of trilobite fossils to explore how fossils preserve information about ancient life. They will sort the fossils into orders (closely related groups) by ...
