    Wood - Arizona?

    I acquired another thing the other day from the same folks who gave me the oncolite slabs I posted in this section... They felt this is wood from Arizona, but didn't seem as confident/precise as I'd like about the location, because of the unusual detail in the wood structure, though I can see it's still agatized and not as detailed as in other pet woods... So based on that and the color I would guess Chinle Fm from Arizona too, but I'd like some other opinions. Yay or nay? If Arizona, where in Arizona? Slab is about 14cm long and 5mm thick.

    petrified wood?

    Found this in the Iron Mountains of Southwest Virginia in Carroll County. It was on the surface of the ground. At first thought it was a piece of wood, which is probably why my mind went straight to petrified wood when I realized it was stone. It has rings, like growth rings of a tree, but I don't have the magnifying tools to make out any smaller structures within the rings. The outer surface also has a barklike texture. Am I right?

    Petrified Wood, Rock?

    I found this in a local stream several months back. The bedrock is Pennsylvanian and in the Glenshaw Formation. It feels strangely heavy for just a rock. Sorry, the scale is in inches. It's about 10.8 cm long. All help is greatly appreciated, thanks!

    Wood?

    I found this piece while walking along a building in Northern Germany...first I thought, "Huh?...this looks out of place"...I thought it was just a weather-worn veiny stone...Then I picked it up, saw the fractures and thought, "Wow!, what a nice piece of Chert or Chalcadony (va. Jasper) what are you doing here?"...The fractures are heavily weather-worn, conchoidial, opaque and with a dull luster... After a while I began thinking that the shape, weathering and banding/striping was a bit unusual (mostly opinion at the time)...I wondered if it might be a fossil...a big Brach maybe? Photos courtesy of the Google ...unlikely After seeing close-ups while cropping the pics to post here, I thought, "Hmmm...I got wood?"... It kinda looks like petrified bark to me now, but its "grainy or veiny" on both sides, which seems strange, to me, for a piece of bark... Probably purely geologic combined with wishful thinking...it happens...although, if it is geology, it would be cool to come across a Genisis Jasper where it should not be Photos courtesy of the Google ...ooops...doin' it again...sry Anyway, either way its a beautiful specimen with an interesting story... Any ideas or opinions?...thoughts will be greatly appreciated...thanks in advance... Have a nice day
  6. I own this silver-mounted snuffbox, made in England circa 1740. Is the lid made of petrified wood, or simply regular agate? The metal portions are silver, with the interior fire-gilt (a highly toxic process that involved mercury vapors!). Thanks in advance for your expert help.

    Petrified wood or not?

    I grabbed this rock as a friend was tossing it out of a flower pot, mostly because it initially looked like petrified wood. After studying it some, I don't think it is, but I am not certain how to identify pet wood (am researching how to do this, though)? I don't see regular patterns on the ends of the rock, which I would expect to find in petrified wood. Is that correct? Found in Alabama, but no idea where it's origin is, since it was in a flower pot. See last photo for size comparison to a water bottle lid - it's a small rock. I checked it for transparency and some edges are transparent but not the entire rock. Thanks! Ramona

    Please be Petrified wood

    So this must be my 4th time posting a pet wood ID request on the forum. It is an older piece I collected with my son last year. Located in Santiago creek river bed in Orange County, California. The specimen lacks any type of wood cell or grain structure at the point where it was cut, however it strongly resembles wood from the outside. The interior is almost entirely quartz and the edges are translucent and emit a yellow glow when placed against a flashlight. I appreciate any insight.

    Petrified Wood ID

    Location: Found along the Moyie river in northern Idaho. This specimen seems to have some characteristics of petrified wood but is difficult to confirm just by looking at it. It is smooth on one end but rough raised layers along the rest. The colors are teal and brown. I want to check with the community to get another opinion before continuing to attempt identifying the specimen. Thank you.
  10. I have several pieces of what I believe to be petrified wood that I discovered on a friend's property recently. I'm no expert hunter or big collector, I've just collected cool rocks I would find as long as I can remember. He has several acres right on the country line, in Knox county. I have researched it though, and all I can find says it's only been found in Savannah, west Tennessee. It's not just a piece or 2, I've got a bunch I've gathered up, and I just started, there's tons and tons of rocks on his property. I downloaded a rock identification app & it agreed I've got alot of petrified wood, agatized wood, fossils & more. But of course, I get different answers on a few but I am pretty sure I just stumbled on a treasure chest of fossils. I think I've also got some Picasso stone, it's beautiful. Agate, calcite, quartz, even a couple that may be Jasper. Several pieces are uniquely shaped, 1 looks like a brain. I've been trying to get good pics of the best, I've got alot more, pics & rocks. Please tell me what you think. I've included a few of the pics from my rock identifier app. You'll see that the same pic gave me a fossil, snakeskin agate, pegmatite & quartz for an answer

    Lycopod?

    Hi all, I'm curious about this piece of wood I found with some interesting, round nodules on the surface. Could it be some species of lycopod? About 3/4 inch in length. Found in Doña Ana county, New Mexico. Camp Rice formation. Thanks for any suggestions!
  12. We find a lot of fossilized wood here in Texas, but as I learn more I’m discovering some may be coral instead. The rock in the first four pictures below I assumed was petrified wood, possibly palm. But as I learn more, it looks like it may have some coral like features? The second couple of pictures are of a light weight rock we’ve come across a few times. Out of curiosity, I cut one in half and cleaned it up with high strength vinegar followed by CLR. I now can see what looks like a branched chalcedony vein running through it and a druzy or two, I believe they’re called. Is it volcanic? A fossil? Or just a kinda cool rock… My wife, 10 year old daughter and I got into rock polishing a year ago. Now we’re trying to learn about fossils because we’re constantly running across them. I appreciate any opinions on both rocks as it’s helping us learn. Have a great week everyone!
  13. Hello everyone. I recently moved to central Tennessee on the Cumberland Plateau where I have been enjoying hunting stone points in the creeks and woods. I recently found some chunks of what I thought might be petrified wood and would be grateful for ID help. Here are the details per the ID TIPS post: Date: Found February 2023 Location: Van Buren County, Tennessee USA Site details: bank of a small creek in close proximity to a spring Found with: a few stone points and stone point fragments and some smaller pieces of possible bone or petrified wood Dimensions: longest side approx. 79mm, width approx. 65mm, thickness approx. 45mm. Weight: 5 oz/142 grams thanks for looking and for any help.
  14. This one given to me by my great grandma, who I believe found it in New Mexico years ago in one of her trips. The bottom has a smooth almost glass like texture, the top is also fairly smooth but not quiet as smooth, and the whole thing is hard as stone. It weighs 5.780 pounds and is 26 inches around and three inches any it’s tallest point. any help on this would be greatly appreciated
  15. Been going through an old collection I haven't looked at in many years and in it are 15 or 20 pieces of wood, collected at the Ernst quarry back in the 90s. I haven't seen any similar examples from Sharktooth Hill or elsewhere. The pieces are somewhat fragile and often partially hollow with small (druzy?) purplish crystals on the interior. The rest is mostly composed of the same purplish-black material but man also show a tougher translucent outer crust. Some of the interiors of these pieces also contain powdery, lightweight chunks of brown matter. Based on appearance and the local geology as well as the preservation of flora from another miocene site in the region (see Reynolds p.114) I'm guessing the dark purplish stuff is pyrolusite or a similar manganese mineral. I assume the tougher clear stuff is microcrystalline quartz. The powdery brown stuff I cannot explain except as mummified wood, but I haven't found any pre-pliocene examples in the fossil record. I'm not a wood guy in general though so maybe there's more out there. What do you think? Something of research value? A small piece (~2.5 cm square) with the two primary minerals. Typical piece. Largest is about 15 cm. The mysterious Brown Matter. Very hard to get a good photo since it's mostly deep in the "geode."

    Possible petrified wood

    Found within creek bed in Orange County, California. Have had this one for some time now. Always thought it looked sort of like petrified wood but is difficult to tell. The answer may be more obvious to someone else. Appreciate any input. Thanks.

    Petrified wood?

    Hi, is this petrified wood or just a rock with a grainy look to it? (Wales)

    Petrified wood in Massachusetts?

    Found this neat little rock in a stream out in some woods while looking for agate. Noticed it had some unusual markings on the side simmilar to how a bug goes under bark, also some faint rings on the top. Made me think it was maybe petrified wood? I know next to nothing about fossils though so I thought I should prolly ask the experts :). It is about 1x1x1cm. Found in Littleton Mass. Anyone have any ideas? Please forgive me if this is just a rock! Just thought it looked woody. What about this guy? Found this when I was digging in the garden. Maybe a foot or two down in Salem, Ma
  19. I found this beautiful piece today along the Arkansas River bank in Colorado. I have a few other pieces of petrified wood but this is the largest that I've found and it almost looks to have been cut with something before hardening. Just curious if this is usual. The cuts are not very deep and I've tried to get the best pictures I can of them.

    Another Wood vs Bone Query

    Hi again Fossil Forum. Picked this one up while I was out collecting petrified wood, but it certainly looks more like bone to my amateur eye. What do you think? Found in Dona Ana county, New Mexico.

    Wood, Bone or Weird Rock?

    I tossed this one in my petrified wood pile because that's mostly what I find out here, but sometimes I see pictures of bone fragments that look similar or that I would have taken for wood had I found it. So what do you guys think? It doesn't stick to the tongue and shows details that could be porousness... but could also not be... There's no obvious cell structure that I can make out. Follow up question: Are there any good ways to tell the difference between wood and bone aside from wood cell structure or visible marrow? This was found in Dona Ana county, NM.
  22. I was hunting a Miocene site in New Zealand when my friend cried out “wow! Wow!….wow!” From a few meters away. Well I thought that’s three wows, this must be something pretty good. She had found the biggest piece of petrified wood I’d ever seen at this site. Pretty good! Not too common as this is outer shelf sediment. We looked around and I found another piece - comparison showed that they fit together…..ok that ups the ante a bit. the whole thing is now about 50cm long well I set the pieces aside and kept looking and mulling over whether to keep this specimen. It’s big, and there’s a big hike out. Maybe I’m better off collecting a photo instead? The time came to decide and I picked up a piece to have closer look…..hang on - that’s a big fish vert in there! You can also see bones and scales poking out the sides. How did we miss this? We were blinded by the excitement of find the massive chunk of wood. My guesstimate of what’s going on below. X-rays confirmed we have an almost complete fish in there. But the piece with the skull in was too thick and dense for X-rays to penetrate. But you can see skull bones protruding out the front You can see the verts running the length of concretion in this image of the second (left hand) block so probably missing the tail? What an interesting association. I tell you though, it was one tricky job stabilizing that wood! It’s poorly mineralised.

    Please help me identify this!

    There are cross hatch patterns in the wood making it almost look woven. The rock imbedded in it or attached to it looks like amber. its bright yellow and dark when no light is behind it. The amber or agate looks like it has some of the same fiber pattern around the edges.
