Aniamls with solid substances in their body can be easily preserved in the right conditions and dug up many years later like all the dinosaurs we've found, for example. However, animals like jellyfish that don't have bones in their body are more likely to be preserved like leaves, that are molded into the dirt.
fish fossils and little animal fossils and also shells

Mineralization occurs in the original remains, inside the shells bones and teeth, of animals and fish. This process turns remains into fossils.
It is the skeleton of an animal or shells pushed under rock for thousands of years and then it is a fossil.
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.

shells, bones and fossils
No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
fossils are something like a plant or bone preserved in rock, then when the preserved thing finally decays there is an impression left in the rock. marine fossils are marine animals, plants, or shells (basically anything in the water, hence marine) that are now fossils.
Some fossils are found in the sedimentary rocks - along with shells and sediment.
They can become sedimentary rock, most likely limestone.
The fossils of their shells, etc.
