This past month I co-chaired a technical session at the national Geological Society of America conference in Denver. The session was entitled "Paleontology, Paleobiogeography, and Stratigraphy of the Late Cretaceous North America Seas: A Tribute to Bill Cobban." Dr. Cobban is a scientist at the US Geological Survey who has over 60 years of experience working on the statigraphy and paleontology of the Late Cretaceous Western Interior Seaway. The Western Interior Seaway (WIS) ran through the middle of the U.S.
The word “fossil” often conjures images of Tyrannosaurus rex skulls, mammoth femurs, or other large bones. But those aren’t the only ones that survive through the millennia, and certainly aren’t the only ones that have importance.
