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?

Hi all, I'm brand new to rockhounding, and found this on the trip that started my interest this summer. I picked this up on a beach in the southern shores of Lake Michigan on the Michigan side. If I had to guess, I'd say it's sandstone with native copper inside. I don't trust my ID, however, because as I said I'm brand new to this hobby, and most of the state's copper is found in the northern regions. Can anyone here tell me if this is native copper? If so, I've seen some beautiful natural copper structures. I would love to get one out of the rock. Would muriatic acid dissolve the rock and leave me with the copper in its natural state? Thanks for any help you can provide!

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...

RARE SNOWFLAKE "MOHAWKITE" MOHAWK MINE MICHIGAN "Snowflake Mohawkite" in Quartz Mohawk mine, Keweenaw Co., Michigan "Mohawkite" is a mixture of copper arsenides, including algodonite and domeykite, of variable composition. It often occurs as irregular masses in the Michigan copper ores of the Keweenaw Peninsula. In this specimen, it fills the spaces between .5 – 1.5 centimeter-sized "snowflakes" made up of radiating quartz crystals--hence the informal name "snowflake mohawkite".

This tooth was found at my trip to Stratford Hall in Montross, VA on December 2nd. I found it laying out in the open among some pebbles. It’s in great condition, but I had some trouble identifying it as it looks quite different from most of the teeth I have found. The roots look as if someone peelled open a banana, and the crown extends very high up the root. There seem to be some very worn serrations on the tooth as well. After some research, I believe it to most likely be from Carcharhinus brachyurus, or Copper/Bronze Whaler shark, although I’m still not sure. I’d really appreciate some input from more experienced collectors who have a better eye. Thanks, and Hoppe fossil hunting!

I know this is likely a long shot, but do any TFF members have the tools and ability to melt down copper into one big ingot for me? Been picking up all the scrap wire for about a year now. Just thought it would be fun to have 1 big Ole bar!
