The boat of a pharaoh was discovered in a sealed crypt and reassembled in a museum near the pyramids (see Fig. The age of our galaxy and earth also can be estimated using radioactive dating.

The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.
However, the age of each fossil primate needs to be determined so that fossils of the same age found in different parts of the world and fossils of different ages can be compared.
This method uses the orientation of the Earth's magnetic field, which has changed through time, to determine ages for fossils and rocks.
Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earth's surface to determine the relative ages of geological events preserved in the rock record.
Numerical ages estimate the date of a geological event and can sometimes reveal quite precisely when a fossil species existed in time.
