polished dinosaur bone

[sjaak]

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!
