Make your own Dinosaur Fossil Dig

Dig Dig Dino! Calling all mini adventures and paleontologist. Go hunting for fossils and treasures of the past with your very own homemade dinosaur dig.

This super easy craft activity will keep little hands busy and musing minds engaged whilst learning about one of their favourite subjects. The best thing is that once you have excavated them all, you can start all over again and use the leftover dig materials to help your garden grow. 


  • Corn starch (2 parts)
  • Warm Water (1 part)
  • Mixing Bowl
  • Dinosaur toys or bones
  • Disposable aluminium pie or cake pan 
  • optional glitter
  • Paintbrush or toothbrush
  • Skewer and mini hammer


  1. In a large mixing bowl, combine the cornflour and water and stir. The amount of cornflour required will depend on the size of dish you are using. 
  2. The mixture should now be thick but still runny enough to pour into your disposable pie dish. 
  3. Carefully Pour all the mixture into the dish. If it is still too runny, add in a little more cornflour
  4. Now it’s time to add in your dinosaur toys or bones. You can add in some glitter if you want to make it a little more jazzy!
  5. Set aside to dry for a day or two before commencing your dig. Best left out in the sun if you want to dry it quickly.   
  6. Remove the tray and place on a chopping board or baking tray outside and begin the search for fossils. 
  7. Taking your mini hammer & skewer start chopping away to reveal the bones and use your paint brush to dust off the fossils for a better look  
  8. Once you have dug up all your dinosaurs, sprinkle the mixture in your garden to help keep bugs away and or in potted plants to help to retain the moisture and reduce watering needs.
