Why is radiocarbon dating not useful for most fossils


Yes, because the layers were still deposited horizontally, even if they are no longer horizontal If a river erodes layers, does the principle of lateral continuity still apply? Geologists measure the abundance of these radioisotopes instead to date rocks. Carbon dating only works for objects that are younger than about 50, years, and most rocks of interest are older than that. Radiometric dating of rocks from the moon and meteorites because they formed at the same time as Earth How old is the Earth? It is constantly being reshaped in a steady, uniform manner What is the basis for understanding the Earth's past? Measuring the ratio of C to C in the remains of dead organisms to determine how much time has passed since the organism died What is the half-life of carbon? A living organism takes in both carbon and carbon from the environment in the same relative proportion that they existed naturally. Younger sedimentary layers are deposited on top of older, horizontal sedimentary layers that have been eroded What is an angular unconformity? It is a surface on a layer of eroded rocks where younger rocks have been deposited How much of a gap in time does an unconformity represent? So, how do we know how old a fossil is? Sediment hardens around a buried organism and when the organism decays, an impression is left What is a cast? Disconformity, angular unconformity, nonconformity What is a disconformity?
