This considers the positions of the different rocks in sequence in relation to each other and the different types of fossil that are found in them.

The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks. Scientists find out the age of a dinosaur fossil by dating not only the rocks in gotham actors dating it lies, but those oof and above it. Sometimes, scientists already know the age of the fossil because fossils of the same species have been found elsewhere and it has been possible to establish accurately from those when the dinosaur lived.

Geologists call this the principle of lateral continuity. A fossil will always be younger than fossils in the beds beneath it and this fheir called the principle of superposition. In an undisturbed sequence of rocks, such as in a cliff face, it is easy to get a rough idea of the ages of the individual strata — the oldest lies at the bottom and the youngest lies at the top.

This is because new sediments are always laid down on top of sediments that have already been deposited.

The sediment of this area was laid down after ammonite A appeared million years ago, and before ammonite B became extinct million years ago. This narrows the date of the delta beds to the four million years between these dates. There are some radioactive elements in rock that decay by giving off energy and turning into different, more stable elements. This radioactive decay takes place at a constant rate gotham actors dating each radioactive element.

Scientists gotham actors dating exactly how long it will take for half the quantity of the element to change, and this state is known as its half-life. After another half-life has passed, the element will have decayed to a quarter of its original amount. After another half-life has passed, it will have decayed to an eighth, and so on. A good example of this is potassium-argon dating.
