Answer:
Not everything that lives becomes a fossil. In fact, very few organisms are lucky enough to be preserved as well as most of the fossils we find. All fossils are found in sedimentary rocks. These are rocks that are formed from loose particles like sand or clay that over time turned to stone. The easiest example of this would be sandstone, which forms when sandy areas are compressed over time so much that the grains chemically fuse together to form one big conglomerate.
So, the first thing you have to do to become a fossil is to die in an area where there is a lot of sediment deposition, like the mouth of a river, and quickly become buried by sediment. Next, you are not allowed to decompose very fast. If you’ve chosen an area with a lot of oxygen for decomposers, then your body will be broken down too quickly and nothing will be left to find! The best fossils are found in areas that used to be anoxic (without Oxygen), where decomposers are not able to break down the organism.
