sjaak Posted February 4, 2017 Share Posted February 4, 2017 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! source: http://scienceblogs.com/notrocketscience/2008/08/06/duckbilled-dinosaur-defended-itself-by-outgrowing-predators/ Link to comment Share on other sites More sharing options...
