We do love everything about dinosaurs. From simple dinosaur crafts and activities to exploring some of the science behind these prehistoric creatures.

These easy dinosaur fossils are great to make with kids and use one of our favourite materials salt dough.

For young children it’s “just” a fun activity for older kids there is actually some science behind it and the process is similar to how to trace fossils are made.

Read on for how to make salt dough fossils with kids.

Dinosaur Fossils

Dinosaur died out a long time ago and the only way that we know that they roamed the earth is through the fossil records.

From fossil bones to trace fossils and more recently fossilised dinosaur tails found in amber, we can see what these great beasts looked like.

Fossils are fascinating and an easy theme to explore with your kids whatever age they are.

You can take a visit to a Natural History Museum and see real fossils, read books about fossils and dinosaurs and then come home and create your own.

Or why not try making some of these other fantastic fun hands-on fossil activities for kids.

Salt Dough Fossils to Make with Kids

These are really easy to make.

We prefer to use our classic salt dough recipe rather than our microwave salt dough recipe so you will need to set aside a few hours to dry in the oven or air dry over a couple of days.

Once dry we painted them to look more like stones and actual fossils but you can, of course, keep them salt dough coloured if you wish.

Fossil Resources to Extend this Activity Further

earth science, rocks and fossil books for kids collage

Encourage more reading and investigation into fossils, rocks and earth science with our favourite earth science books to read to and for kids of all ages.

I’ve found that following the lead with your child’s interest can lead to amazing discoveries for both of you. Throughout this activity I have added further activity suggestions you can find here on Rainy Day Mum however, we are limited as there are only so many hours in the day so these resources from supplies we use and recommend can be used to extend this even further.

The Study of Fossil Kit from Amazon that would make an ideal extension of this salt dough fossil activity with kids.
Dinosaurs themed craft and activity kid for kids perfect for continuing exploring dinosaurs
National Geography Mega Fossil Mine Dig Kit to dig out your own fossils with kids

There is nothing better than getting hands-on holding real fossils in your hands and although the local natural history museum is a good place to start it’s possible to purchase a fossil set that gives information about the fossils and real samples of them.

If your children are fans of dinosaurs this Dinosaur Discovery kit from Green Kids Crafts is a great way to encourage the topic with 5 projects for science and arts and crafts it is a hit in our house.

We are big fans of National Geographic and their kid’s resources here and have brought this Fossil Mine Dig Kit a couple of times now one for each child and it’s gone down a hit. Unlike some of the other versions that contain a plastic dinosaur to piece together, this contains real fossils a big bonus with my kids holding prehistory in their hands.

    1. I have made these before with Preschool Summer Camps. You can air dry them but they take a long time to dry…………. especially the extra thick ones………..lol

  1. I am excited to use with my 23 first graders! I was wondering if you could tell me how many this recipe made. I plan on at least doubling — was just hoping to have a guideline so I won’t have an overabundance or not enough! Thank you so much for sharing! I am sure they will LOVE this!
