  2. Step 1

    Gather your materials. 

  3. Step 2

    Mix 2 cups of flour and 1 cup of salt together in the mixing bowl. 

  4. Step 3

    Gradually add 1 cup of water, stirring as you go, until you have a dough-like consistency. We added several drops of red, yellow, and blue food coloring to make a greenish water that turns the dough brown. 

  5. Tip!

    Don’t make the dough too wet! You may not need a whole cup of water.  

  6. Step 4

    Form the dough into a ball, dust it with flour, and knead it for at least 5 minutes.

  7. Tip!

    The longer you knead your dough, the smoother it will be. If your dough gets too sticky, add more flour to the dough, your hands, or your kneading surface. 

  8. Step 5

    Roll your dough out to about ½-inch to ¼-inch thickness. 

  9. Step 6

    Cut circles out of the dough using either a cookie cutter or a glass. 

  10. Step 7

    Press your dinosaurs into the dough. Then, carefully remove them. Either let your dinosaur fossils air dry, or bake them in the oven at 200 degrees for 2-3 hours.
