What is a fossil?
Can I make a fossil print?
|"Stone" Dough Mix||"Fossils" to Imprint|
|1/2 cup of salt||Twigs|
|1 cup of flour||Leaves (stiff bay leaves work well)|
|1/2 cup of brewed coffee (cold)||Dead, hard-shelled bugs like roly-polys|
|1 cup of used coffee grounds||Seashells|
|Measuring cups||Chicken bones|
|Mixing spoon|| Plastic dinosaur models for
What you are doing is very much like the way real fossil prints were created. A long time ago, plants, bugs, or animals left impressions in soft mud, which dried out and eventually became rock.
Much of what we know about ancient, extinct plants and animals comes from such prints. For example, that is how we know what the texture of dinosaur skin was, and how we are still tracking down the evolution of birds—since neither skin nor feathers are likely to survive as actual fossils, the way bones do.
