Make clay and salt-dough fossil imprints, paint and label them, then arrange an imaginative display to explore basic paleontology and artistic techniques.



Step-by-step guide to Epic Art - Fossils and More
Step 1
Gather all your materials and set them on a clean table so your workspace is ready.
Step 2
Make salt dough by mixing 2 cups flour 1 cup salt 1 cup warm water and 1 tablespoon cooking oil in a bowl until a dough forms.
Step 3
Knead the salt dough on a clean surface for 3 to 5 minutes until it feels smooth and stretchy.
Step 4
Divide the dough into small portions and place each portion on a sheet of parchment paper.
Step 5
Flatten each dough portion to about 1 cm thick with a rolling pin or an empty bottle.
Step 6
Press found objects like leaves shells or small toys into each flattened piece to make fossil imprints.
Step 7
Pinch off a piece of air-dry clay and flatten it into a disc about 1 cm thick.
Step 8
Press other found objects into the clay discs to make different fossil impressions.
Step 9
Ask an adult to preheat the oven to 250°F (120°C).
Step 10
With an adult bake the salt-dough fossils at 250°F (120°C) until they are hard about 2 hours then let them cool.
Step 11
Leave the air-dry clay fossils to harden completely following the package drying time.
Step 12
Paint each dried fossil with your chosen colors and let the paint dry fully.
Step 13
Write short labels for each fossil on small paper strips such as a name or pretend species.
Step 14
Tape or glue the labels next to each fossil and arrange all fossils and labels inside a shoebox or on a tray to create your imaginative display.
Step 15
Share your finished creation on DIY.org

Help!?
What can we use if we don't have parchment paper or air-dry clay?
Use wax paper or a lightly oiled clean surface instead of parchment paper, and if you don't have air-dry clay make extra salt-dough discs (flattened to about 1 cm) and either bake them with the other fossils or let them dry slowly to achieve similar fossil impressions.
My imprints look faint or the dough is sticky—how do I fix that?
If the salt-dough is sticky while kneading, sprinkle in extra flour a tablespoon at a time, and if impressions from leaves, shells, or toys are faint press the found objects more firmly into the 1 cm-thick dough before baking or use a toothpick to deepen details.
How can I adapt this activity for different ages?
For younger kids have an adult pre-measure the 2 cups flour/1 cup salt mix, let them press leaves into the flattened dough on parchment paper and skip oven baking by air-drying extra salt-dough, while older kids can knead independently, handle the 250°F oven with supervision, and paint detailed labels and fossils.
What are some ways to enhance or personalize our fossil display?
After painting each dried fossil, varnish or mod-podge them for durability, create laminated species labels, glue natural materials into the shoebox background, and arrange the labeled fossils with small LED lights for a museum-style display.

Facts about fossils and paleontology
🧪 Paleontology uses both science and art — scientists carefully dig, clean, and sometimes reconstruct fossils like a big jigsaw puzzle.
🥣 Salt-dough fossils are easy to make at home from flour, salt, and water and can be baked to keep impressions for years.
🦕 Some fossils are actual bones or shells, but others are impressions or trace fossils like footprints and burrows.
🖌️ When preparing fossils (real or clay replicas), paleontologists and artists use soft brushes and fine tools to protect tiny details.
🧑🔬 Mary Anning found important Jurassic marine fossils (including ichthyosaurs and plesiosaurs) along the English coast when she was a child.
