Could Fossils Be Preserved in Places We Least Expect — Like Caves?

Fossils, the preserved remains or traces of ancient organisms, have traditionally been associated with sedimentary rock formations exposed at the Earth’s surface. Paleontologists typically search for these prehistoric treasures on eroded hillsides, cliff faces, and in quarries. However, the scientific community is increasingly recognizing that fossil preservation occurs in unexpected environments that challenge conventional understanding. ...
