Carbon fossils can be found in sedimentary rocks such as shale, limestone, and sandstone. These rocks contain organic remains that have been preserved over millions of years, eventually forming into fossil fuels like coal, oil, and natural gas. These deposits are typically found in areas where there was once abundant plant and animal life, such as ancient forests or shallow seas.
Paleontologists are looking for fossils in sedimentary rock.
The deepest fossils ever found are microbial fossils discovered in rocks from the ocean floor, known as serpentinized peridotites, in the Samail Ophiolite in Oman.
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
Yes, mammal fossils can be found in rocks. They are typically found in sedimentary rocks, such as limestone or shale, where the remains of ancient animals have been preserved over time. These fossils provide important insights into the evolution and history of mammals.
Fossils are typically found buried deep in the ground, ranging from a few feet to hundreds of feet below the surface. The depth at which fossils are found can vary depending on factors such as the age of the fossil and the geological processes that have occurred in that area.
