How does a scientist “date” a fossil
WebOne way scientists date fossils and artefacts is to look at the soil layers in which they are found. Because fossils are often found in layers of sedimentary rock, paleontologists can determine their age by examining minerals above or below sedimentary rocks. Paleontologists still use biostratigraphy extensively to date fossils, often internally.
