Our understanding of prehistoric sea creatures has changed. In the Caribbean Sea a 6-inch long shark tooth was found. The carbon dating revealed that the tooth was made around 1.5 million years ago. Scientist have come to a conclusion that this ancestor of the great white shark, called a Megalodon, was about 50 feet long, making it one of the longest vertebrate deep-sea predators known to man. This is an amazing find. Who knows what else lurks below?
