Carcharodon megalodon is an extinct species of shark that lived approximately 28 to 1.5 million years ago, during the Cenozoic Era (late Oligocene to early Pleistocene). Megalodon is regarded as one of the largest and most powerful predators in vertebrate history, fossil remains suggest that this giant shark reached a maximum length of 52–67 feet, and also affirm that it had a worldwide distribution. The open jaws of this massive ancient shark are large enough to drive a small car through when open. Scientists suggest that megalodon looked like a larger and stockier version of the Great White Shark. Megalodon is represented in the fossil record primarily by teeth and fossilized remains of the vertebral column as megalodon's skeleton was formed of cartilage rather than bone, resulting in mostly poorly preserved fossil specimens. The most common megalodon fossils are its teeth. Characteristics include - triangular shape, heavy-duty structure, large size, fine serrations and visible v-shaped neck. Megalodon teeth can measure over 7" in length, and are the largest in size of any known shark species. We are offering a 4.5" long specimen from the Cooper River region of South Carolina, which exhibits much fossilized enamel along edges of the tooth's exterior side and nearly full enamel on its interior side. Exc. A tooth from one of the oceans' top all-time predators is a must have.
