Make Your Own Fossil
What you'll need:
Fossils are extremely useful records of the past. In your case you left behind an impression of an object you own but fossils found by scientists around the world can date back to the time of dinosaurs. These fossils allow paleontologists (the name of scientists who study these types of fossils) to study what life might have been like millions of years ago. Fossils such as the one you made can leave delicate patterns and a surprising amount of detail.
