Question

why are the fossils not in the formation of their rocks

Answer 1

Fossils are often found in sedimentary rocks, which are formed from the accumulation and lithification of sediment over time. The position of fossils within the rocks may be influenced by a number of factors, including the movement of sediment, tectonic processes, and erosion. Fossils can also be displaced from their original location by geological events such as earthquakes or landslides. Additionally, fossils may be reworked into younger rocks through the process of erosion and deposition. Overall, the complex nature of geological processes means that fossils may not always be found in the same formation as the rocks in which they originated.
