Geologists face challenges in accurately reconstructing ancient Ordovician environments, as many species from that period did not possess durable skeletal structures. When an organism dies, its soft tissues decompose quickly, leaving primarily the more resilient components, such as bones, shells, or teeth. If the organism is buried promptly after death, these components can undergo fossilization. However, if an organism lacked durable skeletal structures, its remains may only fossilize under rare conditions. Based on this information, which of the following can be logically inferred from these statements?
