I am not sure, but it might be seeds from a pumpkin....?
Yes Nina, you're absolutely right:) I think this is a very good picture.
I was sure they were pumpkin seeds, too. When my boys were little we would always take the pumpkin seeds and roast them in the oven. Put a little seasoning salt or garlic salt or some type of seasoning on them and dribble a little oil and mix them up well. Roast till dry in the oven at about 350 degrees --- just 15 minutes or so. Delicious! Annette
