Fossils are generally found in sedimentary rock — not igneous rock.Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.C in the atmosphere haven’t been constant throughout history (for instance, Noah’s Flood lowered the total amount of available carbon by burying lots of animals and plants).So something that lived (and died) when the proportion of C was less than normal would appear to have died more years ago than it actually did (for example, it might give an age of 3,000 years before the present, rather than its true age of 2,000 years).So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock (e.g.rock that forms from lava from a volcanic eruption)—perhaps in the rock layers above where the fossil was found, or in the layers below.Of course, the best method is to check the account of a reliable eyewitness, if one is available. Since it is the written Word of God, we can trust it to tell us the truth about the past.Carefully studying the Biblical record, we find that the universe has an age of around 6,000 years, and that a world-changing, global Flood occurred about 4,300 years ago.

Scientists date igneous rock using elements that are slow to decay, such as uranium and potassium.

The universe is full of naturally occurring radioactive elements.

Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.

By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.
