Almost 66 million years ago, an asteroid struck the Earth, killing all non-avian dinosaurs and allowing mammals to dominate.
But just how did we evolve from rat-like creatures running between the feet of dinosaurs to take over their ecological niches? Dr. Kendra Chritz, assistant professor in the UBC department of earth, ocean and atmospheric sciences, aims to find out.
Dr. Chritz is co-leading a new research project to learn how ecosystems and organisms recover after a catastrophic, climate-changing event. She explains in this Q&A that clues may lie in the fossilized teeth of mammals.The Cretaceous-Paleogene extinction event was a really tumultuous time in Earth's history, when a cataclysmic extinction event killed off 75% of the planet's species. It set Earth on a course to become the world that we have today.
We don't know much about this period because fossils of smaller organisms tend to not preserve as well as larger organisms. The fossils are delicate and can become easily damaged over millions of years. Luckily, a few years ago, researchers found a rich trove of mammal fossils from this time period in Colorado a few years ago.
