Their ages
Scientists determine the actual age of trilobites and other fossils using a method called radiometric dating. This involves measuring the ratio of certain radioactive isotopes in the fossil and the surrounding rocks. By comparing this ratio to the known decay rate of the isotopes, scientists can calculate the age of the fossil. Other dating methods, such as relative dating based on the position of the fossil in the rock layers, can also be used to estimate the age of fossils.
Method of determining the age of a mineral that utilizes the damage done by the spontaneous fission of uranium-238, the most abundant isotope of uranium. In geology and archaeology, the process of determining an object's or event's place within a chronological scheme.
index fossils are important for index fossils because they use them to match up rock layers in certain locations that may be far apart! they are ALSO important to scientists because it helps them with relative age!.. HOPE THIS HELPED:]
it means figure it out yourself!
Rodiometric dating
Their ages
The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. The method uses known decay rates.
Dendrochronolgy is tree ring dating wich is one way scientists figure out how old something is
To figure out how old something is based how long it takes elements in the sample to decay.

Radiometric dating techniques (and not just one) associated with investigation of materials originating on Earth and from space allow for the estimate of 4.567 billion years (4.567 × 109 years). A link can be found below which has more information on how the figure was arrived at. This estimate of the age of the Earth is broadly accepted by the vast majority of scientists and scientific organizations around the world.
Radiometric dating is a method used to determine the age of rocks and minerals based on the decay of radioactive isotopes. By measuring the amount of parent and daughter isotopes in a sample, scientists can calculate the age of the material. This technique is commonly used in geology, archaeology, and paleontology to date objects and events in Earth's history.
Radio-Carbon Dating of C-14 carbon dating.
Ultimately, an "element" is defined by the number of protons in the nucleus.To try to figure out what element a specific substance is made up of, scientists can observe it and determine its properties, including color, density, hardness, how it reacts with certain other elements, etc.

Scientists used seismic waves to discover the layers of Earth.
