Megalodon sharks are only known from fossilized teeth. Even before the Renaissance, megalodon teeth had been found, but they were believed to be the petrified tongues of dragons or snakes. In 1667, Danish naturalist Nicolaus Steno, recognized that they were shark teeth. He revealed his findings in a book called The Head of a Shark Dissected.
Whales with bristle teeth eat plankton found on the bottom of the ocean. Whales with real teeth tend to eat animals like seals found in cold waters.
Although there were sharks in the Mesozoic Era, Carcharodon megalodon was not one of them. C. megalodon lived during the Neogene Period, 40 million years after the dinosaurs went extinct.

YES,,, I personally discovered and found megalodon teeth fossils here in the Philippines , can be the first record of megalodon fossils in the Philippines and perhaps may upgrade the records of biodiversity in the country
The only Carcharodon megalodon fossils that have been found are teeth. They lived between 28 and 2 million years ago. They have been discovered all over the world, which is known as a cosmopolitan distribution.
The teeth of the megalodon are about 7 inches long.
The oldest fossilized shark remains that have been found are teeth, identified as the megalodon.
Archeologists have recovered up to 7 inch long Megalodon tooth fossils.
Most sharks have about 3-5 rows of teeth at any time. The front set does most of the work. The first two rows are used for obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth. Megalodon may have had hundreds of teeth at one time.
The megalodon is only known from fossilized teeth. They date from 25 to 2 million years ago. Megalodon died out during the early Quaternary period of the Cenozoic era.
