Hello again,

 

Last year I found this chunck of dinosaur leg bone in the Boulonnais, North of France. Jurassic sediments. See this topic: 

I just polished a small piece and I am very happy with the result. I made a comparison with a picture from the internet of a duck-billed dinosaur on the left and my piece on the right. You can see the growth lines!

This is just a tiny polished fragment to show the micro bone structure and growth rings. For further pictures click on the link above.
