This showcase features a portion of a 11.5-meter tubular core sample that shows physical and biological effects of Earth's collision with a giant asteroid 65 million years ago, which resulted in the extinction of the dinosaurs. The sample, taken from 130 meters below the ocean floor east of St. Augustine, Florida, contains the best preserved Cretaceous/Tertiary sequence yet recovered. The exhibition highlights the work of Smithsonian micropaleontologist Brian Huber, who interprets past climate change by studying tiny marine fossils.
