How to make Dinosaur Fossils? Dinosaur Fossils are so much fun to make and are a great addition for any dinosaur theme learning experience. They are made using salt and can be used in games, sensory activities, role play opportunities and so much more.
Today I am sharing with you how we made our dinosaur fossils and will later share further activities on how we utilised them in learning experiences.
What you will need?
You will need salt, plain flour, water, brown coloured food dye and dinosaur figurines. If you do not have brown food colouring, you could alternatively use watered down brown paint.

Step 1:
- Add coloured water to dry ingredients and mix until mostly combined.
- Turn dough mixture out onto the bench and knead until all ingredients have blended and formed a ball of dough.
Step 2:
- Divide the salt dough into smaller balls. We made 20 but you can make them as big or small as you like.
Step 3:
- Gently press the dinosaur figurines into the dough.
Step 4:
- Place the dinosaur fossils onto a baking tray lined with baking paper.
- Place the tray into a sunny dry space for several hours (or days) to allow the salt dough to completely dry out.
- These fossils can be air dried or placed in the oven on a low heat.
Step: 5
- Once the dinosaur fossils have dried out and harden, the colour appears faded and a lighter colour brown.
- Paint the dinosaur imprints with watered down brown paint to bring out the dinosaur details in the prints.
What now?
Now that we have made the dinosaur fossils, how could we use them in learning and play opportunities? Please stay tuned as I will be sharing a fun and fabulous dinosaur and alphabet activity using these dinosaur fossils soon.

will they crack? I want to make baby imprints with these dough… Thank you
Hi Mae, The dinosaur fossils did not crack and but they are made on a much smaller scale than you would make for a baby imprint. I personally don’t think they would crack but not completely sure. Let us know how you go. Thanks 🙂
Hi,
Thanks for the recipe! I was wondering: how much of each ingredient would I need for 20 fossils?
Thanks again!
Rhonda
Hi Rhonda, to make our 20 fossils I used this recipe https://www.learning4kids.net/2012/12/09/how-to-make-salt-dough-recipe/ On this page you can also print off the recipe if this helps. 1 cup salt, 2 cups flour and ¾ cup water. Thanks 🙂
Thanks so much Janice!
I only have all purpose flour. I made ornaments and they puffed up in the oven like biscuits. If i air dried instead of using the oven do you think they would stay flat?
Cute idea. I wanted to let you know that I am featuring this on a dinosaur birthday party roundup on my site with a photo and link if you don’t mind.
Hi there! I want to use this with my students, but I would love it if they could paint first and after I could put them in the oven. Would I be able to do this without the fossils breaking or any damage happening to them? Or should I just play it safe and have them paint it after?
How to make plant fossils
Hi. Id like to do this activity in a 5 year old classroom…is It possible to dry fosiles without oven or baking them?
Hi, yes it is possible to dry the fossils without baking. Drying them in the oven just speeds up the drying process. Have fun 🙂
