Hi Guys! I finally cleaned up the last batch of rocks from my papa and grandma‘s estate. I know from my last post that I’m not supposed to get some of them wet but they were filthy so I had to clean them before bringing them into the house. Any feedback you have is appreciated. if you saw one of my previous posts, you’ll know that my grandparents collected rocks in Arizona, Wisconsin and Illinois. Most of these are probably from Arizona. I think the one piece of orangish petrified wood #3 is very cool. I would love to know if any of the other ones are petrified wood. To me it’s sort of looked like a pork tenderloin when I was cleaning it today! Maybe that’s just because I didn’t stop for lunch. Ha ha. It was so fun to spend time looking at each and every one. I have a critter living in one of them. Some sort of insect. I did my best trying to encourage him to get the heck out today using water and air but I might have to pull out the tweezers tomorrow! Thanks for looking and have a great week…

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 maybe maybe its obvious what it is, at a glance...to an experienced eye. I've compared it to slag, fossils, even meteorites (extremely unlikely). Any help appreciated. Thanks!

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 verticle and horizontal (car key for scale)- i thought maybe looked like root suckers or corals or burrows (photos 1-3) very interesting bubble-texture and hollow ~ 1cm diameter (photos 4-9)

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 of the grey areas. I am pretty sure the gray part is clay of some sort turned into stone. I was curious about the ironlike outcrops. Could that be parts of trees, limbs or branches that have also turned to stone? Thank you for helping me to identify. ps How did I do on the photos?

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 not sure. Any thoughts on what it could be?

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 it appears metamorphic and significantly heavier or more dense? does not look like a meteor...no shiny smooth surface, etc.... any ideas?

Hi. We found this huge smooth greenish piece of what sounds like metal. It has what looks like small chunks of quartz on the sides. I tried banging it with granite, quartz, other rock types and it has a solid, yet tang sound to it. I scraped it with stainless steel and nothing. Could it be just a raw piece of metal, or a meteorite? Its been sitting there for decades. Im bringing a magnet, drills, metal detector amd other things this weekend to try and help figure out what this is. Any ideas will be greatly appreciated! 1620692906819.3gp

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.

Has anyone seen this before and if so how was it formed? Appears to be sandstone, full of striped layers of metal, in ribbons and bubbles - some bubble features are as large as 9 feet. Never seen anything like it. It was found in the honey creek area of big south fork in Tennessee, outside the town of Onidea. See photos.

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

Is this Stromatilite?
