If a radioactive isotope is said to have a half-life of 5, years that means after 5, years exactly half of it will have decayed from the parent isotope into the daughter isotopes. These isotopes break down at a constant rate over time through radioactive decay. To determine a fossil's age, igneous layers volcanic rock beneath the fossil predating the fossil and above it representing a time after the dinosaur's existence are dated, resulting in a time-range for the dinosaur's life. Fossils, by definition, are the remains or traces of organisms that lived at least 10, years ago. Since the rock formation contains both types of fossils the ago of the rock formation must be in the overlapping date range of to million years. Newer layers are formed on top of older layers, pressurizing them into rocks. Determining the actual existence-span of the species is very approximate. This can often be complicated by the fact that geological forces can cause faulting and tilting of rocks. The same rock formation also contains a type of trilobite that was known to live to million years ago. The earth itself is around 4. After death, organisms tend to decompose quickly. For example, when lava cools, it has no lead content but it does contain some radioactive Uranium U
