New Members h8cru Posted August 20 New Members Share Posted August 20 Hi there, I found a little strangely formed piece of rock some days ago. It was found at the brown coal excavation site of "Tagebau Inden" NRW, Germany. So it could come from everywhere in between 0-230m deep... (that´s the operational depth of the mine) The piece itself is about 10mm long and around 4mm in diameter. It is tube shaped and both ends seem to be broken off, so the piece is not whole. In addition, it seems to be (have been) hollow. There is a round little opening on each end. The tube has regular bumps on the outside, it somehow reminds me of sea urchins shell or other sea life / crustations shells or similar. Maybe I´m wrong, but it does not look like a simple stone Hope you can help me out. Thank you, h8cr8 Link to comment Share on other sites More sharing options...

Fossildude19 Posted August 20 Share Posted August 20 What is the size of this item? Also, can we get pictures of the ends, looking straight on?

debivort Posted August 20 Share Posted August 20 (edited) I think it is a section of ammonite whorl. The ends with the round holes have the cat's paw shape. [edit: maybe? The lack of regularity in shape is throwing me off a bit.] Edited August 20 by debivort 2 Link to comment Share on other sites More sharing options...
New Members h8cru Posted August 20 Author New Members Share Posted August 20 (edited) Hi there, thanks for looking into it! As stated in my post, the piece itself is about 10mm long and around 4mm in diameter. I added additional photos from the ends, with/out lights.
