Why are most fossils found in sedimentary rock?

Fossils form in sedimentary rock because it helps to harden soft body parts of certain organisms. This is why there are so many fossils of worms in the fossil record.

Sedimentary rock is formed in habitats where there are high sedimentation rates. Anything that was deposited would be quickly buried, and decomposition would be low in the anoxic environment.

Fossils form in sedimentary rock because they are dried out while exposed on the surface to the elements, and then are slowly covered with more sedimentary layers.

Fossils typically form in moist, tropical environments because that is where some of the highest levels of biodiversity can be observed. Because of the high number of organisms that live there, it is likely that at least a small number of those organisms will be fossilized.
