Sharks are one of the most successful species in the history of life. They inhabited the oceans of Earth for more than 450 million years. All modern sharks are dwarfed by CHARCHARODON MEGALODON, a gargantuan 50 ft. shark which existed 10-25 million years ago. Its teeth reached a length of up to 7" (21 cm). Excavate, restore and display an authentic 5" (13 cm) reproduction of such a giant MEGALODON tooth which was cast from an original. In addition, your excavations will yield a real 16 million year old shark tooth.
