ziggycardon Posted August 20, 2019 Share Posted August 20, 2019 It is dendrite crystal, often mistaken as fossil due to the branch like patterns it has. Very common in the Solnhofen limestone is Germany where this piece might be from. 1 Interested in all things paleontology, geology, zoology, evolution, natural history and science!

caldigger Posted August 21, 2019 Share Posted August 21, 2019 It is Manganese crystallization that runs through micro fissures in the rock. You will see so many sellers try to pull these off as "plant" fossils, but they are purely geological. Link to comment Share on other sites More sharing options...
