St. Leon Butter Shale, cleaning and prepping tips
jwestbury posted a topic in Fossil PreparationI went to St Leon Indiana, and I had a pretty good haul!!! Spent the day out there I have several fossils that are from the Ordovician time period and they’re in limestone, limestone shale. Does anyone have any good tips on washing them? Do you prefer dry? Just with a brush? What about any rusted stuff, do you use oxalic oxide? What about algae? Do you prefer water? Soap and water? Hydrogen peroxide? I’m afraid and don’t want to ruin any. Thank you!

Is this a meteorite?
AndrewNew posted a topic in Is It Real? How to Recognize Fossil FabricationsHello! I was just sifting through some old stuff and found a peculiar rock that I had discovered when I was a child in a stream somewhere in Massachusetts. I was wondering if this resembles a meteorite? I attached some pics if those might be of help. It's quite a heavy stone, maybe a pound or more. I'm interested to hear what you all think whether real or not!
Fossil or oxidized iron?
Alan A. posted a topic in Fossil IDThree years ago, while diving in a freshwater lake in the Adirondack Mountains of New York state, I came across several long, rust-colored protrusions sticking out from underneath some rocks. The lake is at ~2000 feet of elevation, and the depth of water about 6 feet. One protrusion was a couple feet long, another was shorter; both coming out from the same pile of rocks. I touched the longer one and a ~14" piece broke off, so I brought it up to the surface (see first and second photos below). It is absolutely beautiful--waves and rings like an old tree that's been eaten away. The outside layer
A nail in a fossil?
MrG posted a topic in Fossil IDI don't have much to tell about where this rock was found. It's been in a stash of collected rocks for a while. But I'm curious if anyone has any ideas what it could be. My impression is fossilized wood, but I have no idea what the white band is. There is what appears to be a rusty nail of sorts embedded in it through the darker area and then into the white area. Any ideas?
mr fossil posted a topic in Fossil IDHello! I found this rock in the desert in Saudi Arabia, it felt heavy and I measured its density to be 2.9 g/cm3. I also cut it on the edge and appeared to be iron or some metal but it doesn’t stick to a magnet. what is it?
Tetradium posted a gallery image in Members Gallery
From the album: Platteville to Decorah formation Ordovician Twin CitiesPrasopora conoidea with unidentified bryozoan. You can also see rust stains. Rust stain can be very prevailing in some layers or spots on rocks. Mainly because glacial deposits tend to be very iron rich from Norrthern Minnesota and then they get dissolved in groundwater and redeposit on the fossil shell hash because they're much harder for water to pass through. Another thing to know: Prasopora strongly prefers muddy sediments and thus wont appear or rarely in carbonate rich environment. .
Tully Monster preservation question
rkfrace posted a topic in Fossil PreparationHello all. Does anybody know the best way to preserve a 'Tully monster' specimen. I recall once reading that the surface often needs to be coated with a preservative against oxidizing, etc. One of my specimens has a tiny bit of red on the one eye, which I don't recall being there last year. Please see photos; advice deeply appreciated.

Missouri Mineral/Fossil ID
Torie posted a topic in Fossil IDFound in Jackson County Missouri (I didn't find it myself, but I can most likely get more info on location it was found.) I do believe it was found in a dirt road alley. Long dark grey and brown striations, that cannot be scratched with my nail. Then on one side in a few large chunks, an orange/brown (rust colored) residue, that can be scratched off. I thought my pictures were going to look much better than this. So I can get better pictures ASAP if need be. Let me know any other information I need to provide. Thank you for looking! Hope everyone is
Iron-Petrified Stick with Vines?
twigdigger posted a topic in Fossil IDWhile rockhounding in the area of the Niagara Penninsula, I found an odd-shaped piece of metal about 5 inches beneath very thick, wet mud. The place in which I found the object was in a very shallow stream, which ran over sedimentary rock of the pre-Cambrian shield. After a closer inspection at home, I believe I may have found an iron-mineralized piece of a petrified wood, intertwined with two separate vines. A friend suggested it may be a rusty drill bit although I have doubts based on the location it was found. It is 3 1/2" long and 3/4" wide. It is heavy and seems hard like a metal. It is s
Creek bed fossil
jonplafoy posted a topic in Fossil IDI found this fossil a few weeks ago. It was in a creek bed that flows during the wet season but has pools in the dry. I know the creek has sandstone, but it also looks like it has limestone and possibly slate. There is also a lot of rocks containing rust. This fossil appears to be stained with it. I am located in Western Kentucky near Hopkinsville. One side looks like it is ribs. The other side is smooth and one part is unusually round. There are pockets that appear to be filled with sediment that has solidified into rock. I've added pictures from all sides and others
