Overview
Paleontological techniques in stratigraphy are essential for understanding the Earth's history through the study of rock layers and fossils. By employing methods such as biostratigraphy, lithostratigraphy, and chronostratigraphy, scientists can date rock layers and correlate them across different re...
Key Terms
Example: Geologists use stratigraphy to understand the sequence of geological events.
Example: Biostratigraphy helps identify the age of rock layers based on fossil content.
Example: Lithostratigraphy focuses on the composition and texture of rocks.
Example: Chronostratigraphy uses radiometric dating to determine the age of rocks.
Example: Index fossils are used to identify and date the layers in which they are found.
Example: The geological time scale divides Earth's history into eons, eras, and periods.
