The Stories of Rocks

In today's Presentation of the Day, "The Stories of Rocks" (from PKN New Westminster, Vol. 2), we find that, through studying trace fossils, Johnstone can infer the behavior and the environments of countless ancient species. Using tools and evidence developed by scientists over many years, he can explore the narrative of the rock that he is studying.
