What you’ll learn

  1. How Fossils Are MadeUnderstand the step-by-step process that turns a buried body into a stone fossil.Fossils form when an animal is buried quickly, before it can rot. Water carries minerals into the bones, which harden into a stone copy. Rock forms in stacked layers, so deeper fossils are older. Scientists read these layers to learn an ancient animal's age.
  2. Amazing Kinds Of FossilsRecognize the many different kinds of fossils and what each one teaches us.A fossil is any trace of ancient life turned to stone, not just bones. Footprints are trace fossils showing how animals moved. Insects can be frozen in amber, and coprolites are fossil poop that reveal ancient meals. Hard parts fossilize far more easily than soft ones.
  3. Real Fossil HuntersLearn about famous real fossil hunters and their discoveries.Mary Anning found the first complete ichthyosaur and a plesiosaur along dangerous English cliffs, though she rarely got credit in her time. In America, Marsh and Cope's fierce Bone Wars led to over a hundred new dinosaurs, including Triceratops and Stegosaurus. Fossil hunting has always taken courage and a sharp eye.
  4. Become A Fossil FinderUnderstand how fossils are excavated and how you can safely look for your own.Fossils are dug out slowly with brushes and picks, mapped, then wrapped in plaster to travel safely. Good places to look include cliffs, riverbanks, and quarries, always with a grown-up. If you find one, photograph and report it rather than digging it out, so scientists know exactly where it came from.

Questions this course answers

How does a bone turn into a fossil?

Minerals carried by water fill the tiny holes in the bone and slowly harden, so the bone becomes a stone copy.

Why must an animal be buried quickly to become a fossil?

If a body is not covered fast, animals, sun, and rain break it apart before it can turn to stone.

In stacked rock layers, which fossils are usually the oldest?

New layers pile on top of old ones, so the deeper a fossil is, the older it usually is.

What can a coprolite tell scientists?

A coprolite is fossil poop, and the bits inside show exactly what the animal had for dinner.

How do insects get trapped in amber?

Sticky sap drips over a bug, hardens, and over millions of years becomes clear golden amber.

A fossil footprint is an example of what?

Footprints are trace fossils because they show the mark an animal made, not its body.
