Hello, Found this on a beach in Algarve, Portugal. It looked like a piece of rust, and it was a little magnetic. With pliers, I broke the rust, and inside there was a metallic, hook-shaped object. What can it be? How old could it be? Thanks

Stigmaria, I believe?

Bought this on online auction site recently from a Japanese seller. Its a "viewing stone". Apologies if this is not a fossil. I am a novice. I've done quite a few hours of research, but have decided that I just don't have the experience needed to make an identification. No matter how may pictures I look at and for how long..... I haven't received it yet. It seems to have a hole in the top and one hole on the side. Am not sure if its hollow or if the holes are shallow. The pictures are dark...apologies again. If needed, I will post better pictures when I have it in my hands. Or may

Just finished up this 2nd Priscacara prep job from 18" layer. I'm noticing each fish is its own beast, some are in softer stuff and some harder. Did this one between 20 and 30 psi. I keep getting fish that seem to have damage to the tail before they are buried. Also picked up a 12v electromagnet on Amazon. Works great for collecting the iron powder. Click it on, collect, click it off.

This was a topic of discussion a few times in other threads. I had a small split layer fish I could sacrifice so I gave it a shot with iron powder at low psi. Seems to have worked well. I initially started around 8-10 psi but this was too high. Seems to work well around 5-7 psi. For the harder 18" stuff 30-40 works well. Cheers

Found on the edge of the Gila National Forest in a dry creek bed. Only posted 2 photos because it may be nothing but a rock. Neat markings however.

Hello! 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?

Found this in the Coleraine formation of northern Minnesota, it appears to be bone, possibly a part of an arm or leg, any guesses to what it may be? (I’ve already contacted a paleontologist but I thought I’d ask here, too. Also any tips of removing iron off of fossils? Many of the fossils here are within iron stones and i don’t know how to safely remove most of it.)

2/3 found these on shore of Lake Diefenbaker in Saskatchewan, Canada. looked to be eroded from sandy deposits with layers of harder iron-rich rusty strata. the fossils themselves are heavy, mineralized with iron and then rusted? corals? all the same type or different? i think this is in cretaceous age but not sure. see other 2 posts these specimens are larger, very heavy. like solid iron, looks like outer textured surface mineralized and inner cavity separate - looks like central tubular structure did not mineralized (still sandy) in one pic (could scrape out with toothpick)

3/3 found these on shore of Lake Diefenbaker in Saskatchewan, Canada. looked to be eroded from sandy deposits with layers of harder iron-rich rusty strata. the fossils themselves are heavy, mineralized with iron and then rusted? corals? all the same type or different? i think this is in cretaceous age but not sure. see other 2 posts these samples are really interesting, found in situ, on exposed section of eroding sandy beach cliff - see photos, sand with layers of iron rich strata but these bubble textured rusty iron “tubes” all over, connected and running for long distances

I found this brain shaped object on the south cost of England. It’s very heavy. It is not magnetic.

I am glad I found this forum. I've always been interested about the origins of rocks. Always amazed how something can be turned into stone given time and pressure. Note my most recent find. This odd shaped stone was unlike any others in the stream and was found in New York State, in Hudson Valley, in the Shawangunk Kill. I took it home (really heavy) and pressure washed it. The side that was down is grey and the topside was green. I assumed the green is algae growth but also thought the pressure wash would take it off. The color seems to be embedded. Likley due to the seemingly porous nature o

Manganese and Iron Dendrites
oilshale posted a fossil in *Pseudofossils ( Inorganic objects , markings, or impressions that resemble fossils.)
Dendrites are moss- or tree-like pseudofossils on the margins of rock fissures and fossils, usually on the bedding surfaces of platy limestones and sandstones. Mineral-rich water with high concentrations of iron and manganese has penetrated microscopic cavities between limestone layers, and diffusion-limited growth has created these brown iron and black manganese dendrites, which are often mistaken for fossil ferns or fossil moss.. This slab with manganese and iron dendrites comes from the lithographic limestones of Solnhofen. -
I saw this potential fossil in the Jurassic age Navajo Sandstone in Zion National Park in Utah. I'm sorry that there is only one picture with no scale. I was hurrying down the precarious Angel's Landing trail with a long line of people behind me, so I only had time for a quick picture. The feature is probably about ~12 inches long, and I believe that it is situated on the plane of a cross-bed in a dune structure (example of the cross-bedded sandstone is also pictured). This feature might just be some sort of iron precipitation, but it looked so similar to an invertebrate trace fossil that I am

PA fossil rock ID, very heavy, found near Devonian fossils
LindsayWilson posted a topic in Fossil ID
I found this in our backyard in a rock pile. I find many Devonian fossils in the shale lined creeks around Erie, PA. This rock appears to be similar but is extremely heavy and different colored. I can make out fossils but don’t recognize some of the imprints abs it appears folded and is SUPER heavy. For comparison, the rock I found with it, also pictured here is about 3-4x the size but the smaller one weighs 3x as much. No magnetism, but has a burnt spot. Was it perhaps originally a large piece of the lighter fossil plate that someone burned (possibly in a fire pit?) and that is how i -
San Antonio, Tx 78023 I have this rock from my yard that looks like it’s covered in iron and something else, but below that it looks like it’s been burned.

Still learning my formations. Found these close to the bottom of the Dakota Sandstone formation in Kansas.

Below are 2 items found on the same day after a few days of heavy rain/high creek water. Both of these are heavy and have a hard iron-like shell or covering. The 2nd item was split into 2 pieces when I found it. It is made of the same material as the first. We have iron in our well water at the base of the ridge so I’m very familiar with the color and the smell of iron. These items don’t usually wash up in the creek. I picked them up because their unusual shape and texture contrasted with the creek’s normal sand and gravel.

I’m only posting these because of the similarities in the 2 pieces. Very heavy iron material found in same creek in Arkansas near the Missouri border. Soon to be added to my rock garden.

Chemical Erosion can sometimes be quite artistic
Ludwigia posted a topic in General Fossil Discussion
Last week I visited a new site in the Wutach Valley that a friend had told me about, but after 4 hours of digging and prying and not much to show for it, I decided to call it a day there and spend the remaining few hours checking out a plowed field in the viscinity which usually gave up a few modest finds. But this time I was in luck. The farmer had laid a long furrow on the edge of the field which was exposing a fossiliferously fruitful bed with which I was quite familiar: the Bajocian Macrocephalen-Oolite with among other things lots of Macrocephalites ammonites ripe for the harvest.

NEED HELP!!! Is This Just an Iron Concretion or A Preserved Fossil?
Kurufossils posted a topic in Fossil ID
Hello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded mar -
While 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

Found this on the beach the other day along Puget Sound north of Seattle, and I just polished one face a bit (first photo) with some sandpaper to see the un-weathered stone. Is this siltstone, petrified wood, something else? Has anyone seen one with iron like this? Edit: I sanded it some more and took another photo. Pretty sure this is wood, based on the grain, but I'm no expert!

I wanted to share some of my projects with all of you. A hobby and side business of mine is creating dinosaur sculptures. I do all different kinds of things aside from dinos too, but to keep it relevant, we’ll stick to the mesozoic Featured in my profile picture is my raptor created from scrap metal used to construct railings. I named him Bambi (ironically not a Bambiraptor). Probably more like Deinonychus, he’s a pretty big chicken, but you let me know what you think. As of now he’s my favorite creation, hence why he’s featured in my profile pic. Still trying to figure out the
