Fossil records are like a scrapbook of nature. They tell us the story of life on Earth over millions of years. By looking at fossils, we can see how different species have changed and evolved. This gives us important clues about our planet's history. Here’s how fossil records work:
Preservation: Fossils are made when plants and animals get buried quickly by dirt and mud. Over time, minerals replace the original material, turning them into rocks.
Dating: Scientists have methods to figure out how old these fossils are. This helps us understand when different species lived. For example, trilobites lived over 500 million years ago, showing us what early life forms looked like.
Transitional Fossils: Some fossils show strong connections between different groups of living things. One famous fossil is Archaeopteryx, a bird that also has some features of dinosaurs. This shows how birds and reptiles are related.
In short, fossil records are very important. They help us piece together the puzzle of evolution, showing us how life changes and adapts over time!
