Paleontology
Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.

True. Fossils can be dated using both relative dating methods, which determine the sequence of events in which fossils occurred, and absolute dating methods, which rely on radioactive isotopes to calculate the age of fossils.
Scientists use the following four steps to study fossils: 1. Excavation - careful digging to uncover fossils, 2. Preparation - cleaning and preserving fossils, 3. Description - documenting physical characteristics of fossils, and 4. Analysis - using various methods to interpret the fossils' age, environment, and relationships to other organisms.
Geologists designate different time periods in Earth's ancient past using the geologic time scale, which is divided into eons, eras, periods, epochs, and ages. These divisions are based on significant events in Earth's history, such as mass extinctions, major geological or biological changes, or the appearance of key fossils. The boundaries between these time periods are defined by specific markers in the rock record, such as changes in fossil assemblages or shifts in sedimentation patterns. Geologists use a combination of stratigraphy, radiometric dating, and fossil evidence to accurately assign ages to these time periods.

I love fossils
Using multiple fossils allows for better accuracy in determining the relative age of a rock unit because different fossils may have existed during different time periods. By examining a variety of fossils, scientists can cross-reference their ages and establish a more precise relative age for the rock unit.
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

Periods mean eras centuries ages
By definition, we could say all three fossils are 'ancient'. Fossils provide an ancient record of plants and animals.
You can dig up fossils underground by using the Explorer Kit in the Key items pocket of your bag :)
