Fossil succession
Fossil succession refers to the observation that different types of fossils appear in a specific, predictable order within the layers of sedimentary rock. This pattern reflects the history of life on Earth, with older layers containing simpler organisms and younger layers showing more complex forms. By studying these fossil sequences, scientists can date the rocks and understand how species evolved over time. It serves as a valuable tool for geologists and paleontologists to piece together the Earth's biological history and the changes that have occurred throughout millions of years.

Fossil succession is the principle that layers of sedimentary rock contain fossils of different organisms in a consistent order. This means that as you move up through rock layers, you find fossils that represent different periods of Earth’s history. For instance, certain species are only found in specific layers, indicating they lived during that time. By studying these fossil patterns, scientists can date rocks and understand how life has evolved. Essentially, fossil succession helps us piece together the timeline of life on Earth, showing how different plants and animals appeared and became extinct over millions of years.
