Exceptional Continental Record of Biotic Recovery after the Cretaceous–Paleogene Mass Extinction
Argonne Physics Division Colloquium - 27 Mar 2020
11:00 AM, Building 203 Auditorium

Sixty-six million years ago a 6 mile wide asteroid slammed into Earth and caused the extinction of more than 75% of life on Earth, including the dinosaurs. This was the single worst day for life on Earth. How and when life rebounded in the aftermath of the extinction has been shrouded in mystery due to a poor fossil record. An extraordinary new discovery east of Colorado Springs preserves a remarkably complete fossil record with entire fossil mammals, turtles, crocodiles, and plants and paints a vivid picture of how life rebounded after Earth’s darkest hour.
