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.
Sharks have skeletons made of cartilage, which is less likely to fossilize compared to bone. Additionally, shark bodies are usually scavenged by other marine animals before they can be preserved as fossils.
there's no such thing as a common shark. There are over 400 species of sharks and not one can be deemed common. Lengths can vary from just under 2 feet to as long as almost 20 feet. Unless you seriously count the whale shark as a shark then it goes as high as 50 feet long.
The noun 'shark' is a singular, common, concrete noun; a word for a thing, a living thing.
The shortfin mako shark (Isurus oxyrinchus) is more common than the longfin mako shark (Isurus paucus). Shortfin makos are found in tropical and temperate waters around the world, while longfin makos are typically found in deeper, colder waters.
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.
it was in the palozoic.

There are no fossils on the moon, since the moon has never been able to support living creatures.
Yes, unless you are talking about a specific shark. But shark itself is common.

Shark teeth fossils found in the mountains of North Carolina are a result of the area being underwater millions of years ago. During that time, the movement of tectonic plates caused the seabed with shark teeth to be pushed up to form the mountains. The shark teeth fossils are evidence of the region's geological history and ancient marine ecosystems.
