Is most likely to become preserved fossil?

Most likely to become a preserved fossil are organisms with hard parts, such as bones, teeth, and shells, as they are more resistant to decay. Additionally, rapid burial in sediment and anoxic (low-oxygen) environments enhance preservation by limiting decomposition and scavenging. Organisms living in or near water bodies, like rivers or lakes, are also more likely to fossilize due to the conducive conditions for sediment accumulation. Overall, the combination of hard structures and favorable burial conditions significantly increases the likelihood of fossilization.
