Fun Fossil Stamps and Desktop Fossils



  • Pen
  • Paper
  • Scissors
  • Styrofoam Plate
  • Tape
  • Marker
  • Air Dry Clay


  1. Find a picture of a fossil to base your stamp off of. There are plenty on the Web, make sure yours is not too complicated (for example, a skull or bone works better than a whole skeleton)
  2. Print the picture or trace it onto a sheet of paper.
  3. Cut the flat center out of the Styrofoam plate.
  4. Place the fossil image onto the Styrofoam, then draw over it with a pen. Push hard enough that the design transfers to the foam beneath the image.
  5. Remove the paper, and you should be able to see your fossil image in the Styrofoam. Draw over the image once more with the pen.
  6. Your stamp is almost done! You can make a handle out of tape by sticking a loop to the back of the Styrofoam. Color over the front of the stamp with a marker or highlighter, then quickly press it firmly onto a sheet of paper.
  7. To make a clay ‘fossil’ using similar methods, repeat steps 1-5.
  8. Trace over the fossil image three or four times with a pen, pushing firmly into the Styrofoam.
  9. It should be easy to pop the center of the fossil picture out of the Styrofoam. If it isn’t, draw over the outline one or two more times. Gently pull the center out of the fossil design
  10. Use the fossil cut-out you just made to make a fossil imprint on a flat piece of air-dry clay. Peel the cut-out off of the clay and let it dry according to the clay’s instructions.
