The parts of organisms are most likely to become fossils.?

The parts of organisms most likely to become fossils are hard structures, such as bones, teeth, and shells, because their mineralized composition makes them more resistant to decay and erosion. Soft tissues and organs typically decompose quickly and are less likely to be preserved. Additionally, organisms that lived in sediment-rich environments, where rapid burial can occur, have a higher chance of fossilization. Overall, the likelihood of fossilization also depends on environmental conditions and the presence of suitable sediment.
