= | =How to date fossil remains?= | ||
There are two ways to date fossil remains: relative dating and physical dating. The first method calculates the layers and the origin of the deposits on the fossil. The second method uses natural clocks (that use physical properties) to calculate how much time has passed since the organism has died. The most famous method is called radiocarbon dating which detects carbon-14 (which is a form of carbon). By measuring the amount of carbon-14 left in the deceased organism, we can determine when the organism died. Another technique that combines relative and physical dating is palaeomagnetism. It uses the Earth's magnetic poles and the position at which they were when the organism died, allowing us to calculate at which period of time that was. | |||
