Amino acid dating: Physical structure of living beings depends on the protein content in their bodies.

When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:1.

Provide an idea of the sequence in which events have occurred.2.

Stratigraphy: The oldest dating method which studies the successive placement of layers.

It is based on the concept that the lowest layer is the oldest and the topmost layer is the youngest.

Radiometric dating: This technique solely depends on the traces of radioactive isotopes found in fossils.

The rate of decay of these elements helps determine their age, and in turn the age of the rocks.

The area of intersection of both sets depicts the functions common to both.

Take a look at the diagram to understand their common functions.

Dendrochronology - also known more informally as Dendro or Tree Ring dating - is one of the most accurate methods of absolute dating in archaeology.

Scientists can count and measure annual ring widths to a very accurate degree, these measurements are analysed statistically to produce reference sequences.
