      Teeth and bones. THey are formed from proteins like collagen which give good rigid structure, and then have lots of calcium ions deposited on top to mineralise them and make them hard and solid.

      I can’t think of anything harder than that in our bodies.

      Yep – teeth and bones. I would probably say teeth over bones slightly though because of the enamel on the tooth crown: that is if you keep your teeth healthy and they are not full of fillings of course 😉
