Dr. Tyler Lyson is a vertebrate paleontologist who studies the extinction of the dinosaurs, the rise of placental mammals, and the evolutionary origin of various reptiles, particularly turtles. He combines developmental, genetic, and fossil data with high-resolution chronostratigraphic data to address his research questions. Tyler has conducted fieldwork throughout the American West and has active field sites in North Dakota, Montana, and Colorado. Tyler was born in North Dakota and has been doing paleontology fieldwork since he was in middle school. Tyler received his BA from Swarthmore College and his PhD from Yale University. Tyler joined the Museum in 2014 after a postdoctoral position at the Smithsonian Institution.

Earth's Last Dinosaur Ecosystem
Join Dr. Tyler Lyson, associate curator of vertebrate paleontology, for a discussion on how the fossil records of plants and animals help to address the tempo and cause(s) of Earth's last mass extinction event.
After the Asteroid: Colorado Discovery that Rocked the World
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 paints a vivid picture of how life rebounded after Earth's darkest hour.
