Scientists have found fossils of a new shark that is believed to be the true ancestor of the white shark - the planet's largest predatory shark.
During the past 150 years, the evolution of white sharks has caused a lot of controversy in paleontology. This species has been classified as a megatooth shark with an ancestor, the largest predatory shark that ever lived Carcharocles megalodon.
However, according to the new mako shark fossil analysis dating back to 6.5 million years, the paleontologist at Monmouth University in New Jersey said that white sharks have ancestors through intermediate stages are sharks. Mako, then proceeds to the direct ancestor of the modern shark, the Hubbelli white shark.
Mako shark teeth have the same amount of matching white shark teeth.
Because fossils show that mako sharks have the same number of teeth as the current white shark with 222 teeth and 45 vertebrae. While modern sharks are jagged on teeth to eat and swallow marine mammals, while mako sharks lack serrated teeth because they mostly eat fish, but Hubbelli white shark there is a coarse jagged layer, showing a transition from mako sharks to modern sharks.
It is known that the current great white shark (Carcharodon Carcharias) is the largest predatory shark in the world, has a length of 20 feet (6 meters) and is more than 5,000 pounds (2.5 tons), often hunting in waters in the Atlantic, Pacific and Indian Ocean. They can swim 43 miles (about 80km) an hour to chase prey.
