"Stratigraphy and Paleontology of the Upper Cretaceous of the Pacific Northwest"

"Stratigraphy and Paleontology of the Upper Cretaceous of the Pacific Northwest" studies the layers of rocks (stratigraphy) and the fossils preserved within them (paleontology) from the late Cretaceous period in the Pacific Northwest region of North America. This research helps scientists understand the Earth's history, climate, and ecosystems during that time, revealing how ancient environments looked and how life—like dinosaurs, marine animals, and plants—evolved and interacted. Analyzing these rock layers and fossils provides insights into changes over millions of years, informing our knowledge of prehistoric life and geological processes in this region.
