Kallie Moore manages the paleontology collection at the University of Montana and co-hosts the YouTube channel PBS Eons. Her love of paleontology started from a young age, and she even searched for tiny fossils in the gravel on her grade school's playground during recess. Kallie has consulted for Disney's Animal Kingdom Theme Park on renovations to the DINOSAUR ride, as well as hosted a livestream for the newly opened Deep Time Hall at the Smithsonian National Museum of Natural History in Washington, D.C.
