A decomposing body of a dead animal does not always leave ''fossils''.
Only a very small percentage die in the right conditions to survive MILLIONS of years.

The actual likelyhood of anything ever fossilising is very low. The conditions have to be ideal. Scavengers dismember the corpse, weather wears it down etc. The fact that we have fossils just shows how many dinosaurs there were. I read somewhere that experts estimate that we may have only discovered as little as 10% of dinosaur species.

there have been about 200 Dinosaurs found that were more or less intact. Dinosaur and Mammoth remains have also been found under the sea.The problem with locating Dinosaur remains is we are not sure where they are located. It is like looking for a needle in the proverbial haystack.The ones found under the sea are from the days when the land was joined to other land. When the ice age melted then these seas were formed and the land was no longer joined.

Many of the dinosaurs that have been fossilized died of natural causes or before the asteroid that struck earth, therefore there bones remained intact. However, the others that were located anywhere remotely near to asteroids epicenter were vaporized.
-
Because most organisms do not have the perfect conditions needed for fossilization when they die.
