Only the teeth are found , because a sharks skeleton is made out of cartilage. This results in poor to no fossilization of their skeletons and therefore is rarely found. I hope this is a sufficient answer.

∙ 11y agoCommon fossils of sharks mainly include the thousands of teeth lost by ancient sharks. It is extremely rare to find the exoskeleton of a shark because they are 99% cartilage and it is very soft and is biodegradable. A very common and popular shark tooth find is the megalodon. The shark grew up to 65 feet and could kill a sperm whale with one bite! The largest complete megalodon tooth on record is 7" and is nearly as sharp as a serrated knife. But no worries, the shark went extinct over 65 million years ago and there are none in Earth's waters.....we think.

is a megalodion shark?
There are no shark species with that name. I guess you were asking if the are MEGALODON sharks; in this case, the answer is afirmative. C. Megalodon was the largest known shark ever, and it is belived to be very recently extinct (in geological time scale). We have a large fossil register, mostly teeth but also some rare vertebral centra, which is made of a very hard cartilage. The oldest fossils of Megalodon are teeth dated from the late Oligocene (about 30-28 milions of years ago), and the more recent fossils are only one and a half million years old.
