If the Late Cretaceous seas had a boss fight, it was Mosasaurus hoffmanni. Stretching up to 15 meters long (longer than a school bus), this marine reptile wasn’t a dinosaur, but a relative of modern monitor lizards and snakes. With a double-hinged jaw and rows of sharp, backward-curving teeth, it swallowed prey whole—fish, sharks, turtles, even other mosasaurs were on the menu. Fossils suggest it dominated oceans worldwide, making it the undisputed apex predator of its era. This hard enamel pin captures its massive head and toothy grin in polished metal and enamel—no submersible or fossil dive required. Specs: Premium metal base with polished hard enamel fill Secure clasp so your Mosasaurus doesn’t “swim off” Size: 37 x 30mm Zero chance of raiding your aquarium Perfect for marine reptile fans, dino-era enthusiasts, and anyone who likes their monsters with extra teeth and oceanic swagger.
