Hi everyone, I was given this fossil that has some copper foil on it. Does anyone know why this foil is there? I have reached out to a couple shops like Fossil Era and they had no clue... if anyone has seen this I'd love to understand more. Attached are a picture of the foil, as well as the documentation that came with the gift, in case that looks familiar to anyone. Thank you for your time, David

I purchased this from a shop in Iowa that said it was a glacial erratic. Does anyone have any idea on what type of coral it is?

The hardness of my fossil is over a 5 on the hardness scale because it does cut glass. It's so heavy just for a small chunk, has shale like layers, sorta chalky, and has the most remarkable glittery dust of green copper red gold blue sparkles to it but very small it's best to use a magnifier to get good close up look. It's black in some areas as if it we're magma or from lava flow. What is the glittery part in fossils?

I've notice some smaller armatures for articulated animals are copper and not steel. Is there a good reason for this? I'm about to build my own and have more experience with steel. Sure, it can be heavier and harder to bend, but I don't plan on taking my dino camping with me...
