It must avoid scavengers and decomposers that would destroy its remains, and it needs to have hard body structures. Soft body structures will decay. Even if a fossil does form, it might not be found. Fossils are sometimes crushed, weathered, eroded and even melted before they are ever discovered. Based on the passage, which of these best describes fossils?
