Whats a trilobite.

Trilobite. The trilobites are a large group of extinct marine arthropods, the Class Trilobita, characterized by the longitudinal division of the exoskeleton into three lobes—a convex central (axial) lobe flanked on each side by a flatter pleural area (Fig. 1)—hence their name.

The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation. The Wheeler Formation has been previously dated to approximately 507 million year old, so ... Index fossils are used in the formal architecture of geologic time for defining the ages, epochs, periods, and eras of the geologic time scale.
