Like other sharks, Megalodon's skeleton is made of cartilage, not bone. That means it doesn't fossilize well. The vast majority of Megalodon fossils that we have are teeth, and we also have a few vertebrae. From these, we can tell that Megalodon was a huge shark, but it is still difficult to get an exact size estimate (maximum figures say it was about 50+ feet long, compared with great whites which are only 20 feet long, at the largest). We also know that Megalodon had a global distribution, and that it lived between 15.9 and 2.6 million years ago. The other thing we know is that they probably ate cetaceans, such as whales, because some whale skeletons from the period show tooth marks that match those of Megalodon.
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.

There are many clues to what ancient climates were like. One of them include what fossils are found in an area.
Fossils help us learn about the past, like if a fish fossil was in your backyard, then your backyard was covered with water. They also help us with the fossils where the setting was then, and what animals lived there.

Scientists learn about dinosaurs by studying their fossils and those of other contemporary organisms. This helps them to learn what a dinosaur looked like, what it ate, and what its adaptations were. They also learn about what the climate, plant life, and other animals it interacted with were like. Fossils such as those of eggs, nests, and footprints can leave clues as to a dinosaur's social behavior.
