Around 66 million years ago, an entire ecosystem disappeared, leaving nothing behind but a mysterious multitude of bones. How the ill-fated dinosaurs met their demise is debated to this day. Still, whether vanishing via a massive meteorite or an unprecedented volcanic eruption, it’s clear that these fascinating creatures left behind a mammoth legacy. The perfect gift for little dinos and old fossils alike, this clever, heat-sensitive ceramic mug is sure to make an equally impressive impact. All it takes is a warm beverage poured within to turn the glamorous, gangly dinos on its surface into mere shells of their former shelves – skeletons, to be precise. Watch eons pass in the blink of an eye – turning feisty new friends to fossils faster than you can say “Watch out for that asteroid!” Holds 12 oz. Disappearing mugs are not dishwasher safe but are microwave safe.
