Unique wood from Round Mountain Silt, anyone seen anything like this?
H. Drax posted a topic in General Fossil Discussion
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."

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.

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

Petrified Wood with what looks to be cuts in it
ImmaFrayedKnot posted a topic in Questions & Answers
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.

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.
-
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.

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.

Hello, 56 year old new member here. I enjoy looking for fossils as a child and I found this piece of petrified wood on our property yesterday. Anyone had any information about petrified wood in northeastern Ohio? Steve

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.

I went out to Arizona this fall. Still looking for mammoth, but did come back with triassic petrified wood. The Petrified Forest is outside of Holbrook. It really is a whole petrified forest that was brought down by massive floods-- whole trees no branches no leaves. After that i went looking for wood i could take home. Near the Petrified forest is a paid dig site DoBell ranch. It looks like something out of "American Picker " with the old trucks and and the old buildings. There were visitors there who went to town digging. I stayed with surface finds and and came home with more wood than I know what to do with-- in great colors.

Hi everyone, I was on my way to my doctors appointment. I was walking to the door, when this caught my eye in the gravel. I thought it was wood at first, but I was mistaken. It’s definitely a rock. It was found in Twin Falls, Idaho, near the sidewalk. I’m looking for confirmation. Is this petrified wood? If it is, it’s my first find of 2023! Jared

I found this in my yard decades ago in Brenham, Tx. However, the previous owner, who had died, was quite the rock collector and left the yard filled with petrified wood, large and small so I don't know where he got them. My family also collects rocks and fossils so I made sure to haul a many as I could when we moved to NY. My question- is this amber on the rock? It's not a fake, it's not glue, but when I google for info it claims amber on wood is very rare. Could anyone tell me what they think? Thank you I added another picture to show what looks like more light colored resin in another area

I had just recently finished polishing a piece of petrified wood I found, and I just read a topic that included a polished pyritized Yorkshire cannonball ammonite, which got me thinking about all the types of fossils that can be polished. I did a search on the forum for a "Show us your" polished fossils thread and couldn't find any so decided to start one as I'm interested to see the diversity of fossils that have been polished. So... Show us your Polished Fossils!

Back in August I was catching feeder fish in a wretched little Woodbine tributary when I pulled this out of the muck. It was black and limestone color with thick algae, it was unrecognizable as wood but there were holes and ripples that gave me hope. Hauling this (24 lbs) and my gear & fish was a challenge up a vertical bank and 100 yd walk through thick thorny brush for a 100 lb person, almost left it halfway back to car. After a good scrubbing it still looked like a chunk of water worn sediment and I deleted the first pic of top side, then I tried a new cleaning method I was using on ammonites that were badly stained and got great results. Pictures 1 & 2 show before and after on bottom side but the top was even worse. It won't win any beauty contest I was just happy it was wood. Thinking it was decaying wood and it is full of piddock clams, #5 shows one well. The things in question are 3 & 4, which I'm wondering could they be soft body fossils of Toredo worm? In pics of #4 the black object looks like part of the shell maybe, but #3 looks segmented like a caterpillar which Toredos are not, picture 5 shows one end of it above clam. So what could they be?

I found a piece of petrified wood that looks very similar to this that has sap and a couple tiny snails eating the sap from what it looks like. I polished a small section of it and it’s like a mirror graphite color. Anyway, I can post some images here soon if anyone is still around and interested to see. Really just looking to learn more about it if possible!

Not sure what this is could not find my measuring tape but am estimating it to be about a little longer than an inch.

Hi again, Fossil Forum! I've got a stone which I think is wood, but it's iffy enough for me to ask for a second opinion. Found in Doña Ana County, New Mexico. There is a lot of it out here! Anyway, let me know what you think! Size is roughly 3.5 cm wide, 3.5 cm tall, 1.5 cm thick at its thickest edge.

These were from a creek bed with some great exposure. Abundant Ammonite impressions and oysters and some great layered bedd deposits. These pieces have me scratching my head. One looks like it could be a coral or crinoid base? Some appear to have bark impressions and look like stem pieces. The curved one is also interesting. Seems to uniform for just a rock. I’ll post them individually Thanks! patrick

Part two…looks like stems …Maybe, palm, cycad or fern? I guess another possibility is bone.. ?

From the album: PLANT, WOOD & MINERAL SPECIMENS
In the Early Pleistocene, about two million years ago, these twigs and bits of trunk were driftwood in the paleo Santa Fe River. The waterlogged twigs sank to the bottom in a basin in the river channel. They became buried in a highly organic mud during seasonal flooding. This anaerobic, low-energy burial preserved fine details such as bark and even insect borings. The wood is thoroughly mineralized with apatite (not "silicified" as labelled) -- it 'clanks' when two pieces are tapped together. This wood is dated biochronologically by the vertebrate fossils also found in the mud, notably Holmesina floridana, a giant armadillo. Fossils of the beavers Castor and Castoroides, muskrats, grebes, cormorants, ducks, and large fish suggest that this was a backwater pool in the river.© ©Harry Pristis 2008

From the album: PLANT, WOOD & MINERAL SPECIMENS
The common practice for petrified wood is to use "form genera" names for specimens, thus all petrified palm fiber is described as Palmoxylon sp and the roots as Rhizopalmoxylon sp. The reason for this convention is that the wood rarely gets as much attention as the foliage when plants are described and these components are rarely, if ever, found attached.

This bit of petrified wood, largely replaced by apatite (calcium phosphate), exhibits some damage from insects, or it may be a canker from a bacterial or viral infection. You can see other images with a brief discussion here: http://www.thefossil...ogy#entry368790 In the Early Pleistocene, about two million years ago, these twigs and bits of trunk were driftwood in the paleo Santa Fe River. The waterlogged twigs sank to the bottom in a basin in the river channel. They became buried in a highly organic mud during seasonal flooding. This anaerobic, low-energy burial preserved fine details such as bark and even insect borings. The wood is thoroughly permineralized with fluorapatite -- it 'clanks' when two pieces are tapped together. The flourapatite comes from the mineral-laden spring-water of the river.

Hi. We picked this up thinking it was a piece of petrified wood. But upon closer inspection we think it could be something else. Our family is still learning and this has us stumped. It was found on one of the beaches in southern Oregon, we don’t remember which one. Thanks!
