Make a fossil using coffee dough

You will need:

  • 1 cup used coffee grounds
  • 1/2 cup cold coffee
  • 1 cup plain flour
  • 1/2 cup salt
  • Mixing bowl
  • Wax paper
  • Objects with which to make 'fossils'

Instructions


1. Mix the ingredients together and knead the dough until soft.

2. Spread the dough onto wax paper and cut round shapes using a knife, jar, glass or cookie cutter.

3. Press objects into the soft dough to make 'fossil' impressions.

4. The dough can be left to harden overnight.

Dinosaur traces are often in the form of impressions left in mud.

The impression can be of a bone, skin, egg fragment or tooth. Once the mud hardens into stone the impression is preserved... hopefully avoiding erosion from water and wind so that paleontologists get to look at the impression.

Dinosaurs aren't the only fossils found in rocks. All manner of living things can be found if you know where to look. Try going for a walk along a rocky headland next time you're at the beach. If you look into these rocks you can often find impressions of ancient marine organisms.
