Hi, always from the Omhden (DE) quarry. I'm wondering what this dark mineral actually could be... I'll report 2 different speciments, both about 10-15cm in length. They have little white "spiderweb" across the dark lucid surface. it is like 1mm thick this could be really useful for beginners like me thanks a lot Paolo

Hi, My name is Neal, I found this rock on the side of a railroad bed near Caro, MI. It is heavy for it's size, and has quite a bit of porosity to it. Any help would be appreciated. Thanks!!

Hello. I signed up this evening after I looked over the board. As knowledgeable as the members here are I was hopeful you could help me. I know nothing about fossils, except they're mostly really old. Anyway, the ones in the pictures are from the Middle East (at least that's what my friend said). I tried to get the picture as clear as I could. I hope it's up to par. And thank you for your help! Greg.
