Dinosaur fossil eggs for Easter?

If you are like me, you are always on the lookout for something egg or bunny related for Easter, especially something that is not chocolate. These DIY dinosaur eggs are perfect!

Not only will your child not be overdosing on candy, but they can practice their fine motor skills while removing the fossil from the egg. It’s much more educational too – will your child be able to identify their discovery?

There are various sets available if you don’t want to make your own (though this one is so easy, you will want to make your own):

DIY dinosaur eggs are great for birthdays too!

Are you throwing a dino-themed birthday party for your child? these dinosaur fossil eggs make great party favours. They are inexpensive, easy to make and your little dinosaur fan can tell their friends that they made them.

If you are looking for activities for your guests to do at the party, fossil discovery is a great, simple game and the guests can take any fossils they find a home with them.

Why you want to make these dinosaur fossil eggs

There are so many reasons to make these DIY dinosaur eggs:

  1. You are likely to have almost everything you need already – possibly everything, depending on your little dinosaur fan’s collection of toy dinosaurs and toy fossils. And who needs an excuse to drink coffee? If you don’t have a sandpit, sand can be purchased at a hardware store.
  2. They are relatively cheap – even cheaper if you already have the toy dinosaurs.
  3. They are so easy to make. You can do it even if you are distracted. With just a few instructions, your little dinosaur fan could even make them on their own – our LDA did most of the work and she is only 5.
  4. They take almost no time to make – even less time if you decide to dry them in the oven.
  5. Your little dinosaur fan can uncover the fossils at almost any time, regardless of the weather.

You can fill the eggs with dinosaur fossils, fossil skulls, small dinosaurs, dinosaur bones and even real fossils. If you are making some for someone who is not as keen on dinosaurs, you can fill them with things that have nothing to do with dinosaurs – unicorns.

The best thing about these dinosaur fossil eggs: the egg-scavation

The real fun for your little dinosaur fan is not in the making of these dinosaur fossil eggs, but in their excavation. A tip from one Mum to another though: make sure any excavation takes places outside because it will make a mess!

Easy DIY dinosaur fossil eggs

Yield: 4-5 eggs
Prep Time: 5 minutes
Active Time: 5 minutes
Additional Time: 3 days 20 minutes
Total Time: 3 days 30 minutes

These DIY dinosaur fossil eggs are so easy to make - and excavating them is the best bit! They're perfect for Easter, birthday parties or any time your little dinosaur fan needs some distraction.


  • 1 cup plain flour
  • 1 cup used coffee grounds
  • 1/2 cup salt
  • 1/4 cup sand
  • 3/4 cup water
  • 5 small toy dinosaur fossils (or similar)


  • 1 mixing bowl
  • Measuring cups
  • Baking tray


    1. Add all of the dry ingredients to a mixing bowl. Step 1: Pour all the dry ingredients into the bowl and mix to combine. The dinosaurs do not need to be in the bowl!
    2. Slowly add the water, mixing and kneading with your hands until it forms a "dough" that holds together. Step 2: Add just enough water so that it forms a dough.
    3. Take a small handful of dough, add a dinosaur fossil or other toy and add another handful of dough on top. Form the dough into an egg shape that entirely covers the toy, adding more dough as needed. Form your eggs with the dough, hiding a dinosaur fossil inside each one. Leave for a few days or until totally dry
    4. Let the eggs air dry for 2-4 days or until hard. If you need the eggs earlier, place them on a lined baking tray and bake at your oven's lowest temperature for 15-20 minutes or until hard.


Add the water slowly until the ingredients just hold together enough. If your coffee grounds are still damp, you won't need as much water.
