Fascinating Fossils: Unearthing the Secrets of the Past
Fossils are like puzzle pieces from the past. They are the remains of plants or animals that lived millions of years ago. Imagine a leaf falling into a muddy river and getting buried under layers of sand. Over millions of years, the mud hardens and turns into rock, preserving the shape of the leaf. That's a fossil! Paleontologists, or fossil scientists, study these natural treasures to learn about extinct creatures and how they lived. Did you know that dinosaurs are known to us only through fossils? For instance, the Argentinosaurus, whose fossilized bones suggest it was the length of three school buses! Fossils give us a glimpse into the past, helping us understand life on Earth long before we were here.
