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.

How to make dinosaur fossils - 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.

  • 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.

    1. 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 🙂

  1. Hi,

    Thanks for the recipe! I was wondering: how much of each ingredient would I need for 20 fossils?

    Thanks again!


  2. 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?

  3. 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.

  4. 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?

    Hi. Id like to do this activity in a 5 year old classroom…is It possible to dry fosiles without oven or baking them?
