Relive the 5th mass extinction event on Earth (The Cretaceous-Paleogene extinction event, to be precise) with this temperature-sensitive coffee mug. Watch as the dinosaurs in the image change from living to extinct, leaving only their bones behind, when hot liquid is poured into the mug. Slowly, the image will revert back to the living dinosaurs as the hot liquid inside cools or is removed. A fun paleontological conversation starter for the home or the office.
