Fossil radiometric dating

More information
The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages. There are several different methods for estimating the ages of fossils, including:. Paleontologists rely on stratigraphy to date fossils.

Methods of Dating Fossils | History of Life on Earth

Metrics details. Earth scientists have devised many complementary and consistent techniques to estimate the ages of geologic events. Annually deposited layers of sediments or ice document hundreds of thousands of years of continuous Earth history. Gradual rates of mountain building, erosion of mountains, and the motions of tectonic plates imply hundreds of millions of years of change. Radiometric dating, which relies on the predictable decay of radioactive isotopes of carbon, uranium, potassium, and other elements, provides accurate age estimates for events back to the formation of Earth more than 4. Historians love to quote the dates of famous events in human history. They recount days of national loss and tragedy like December 7, and September 11,

Radiometric Age Dating

In fact, I believe that the question of how long life has existed on earth is even more important than the question of whether life was created or evolved. You see, the theory of evolution has so many problems that most people find evolution hard to accept, and I don't think many people are led to question their faith because of it. It just doesn't seem reasonable that life could develop on its own by chance, and the evidence that this actually happened is missing. It's also not a problem that geologists say that the sedimentary layers of rock took millions of years to form, since there are many evidences that the great geological formations on earth were formed rapidly and catastropically, as in the Biblical flood or subsequent catastrophic events.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
