    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.
  2. 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 ke

    Petrified Wood Slabs

    I'm interested in petrified wood for the scientific value (wood where the cell structure is well preserved), for the aesthetic value (mineralized with vivid colors and crystal shapes), and for oddities (like fungus, insect borings etc.) contained in the wood. Below are three petrified wood slabs, from the United States, from my collection. The below individual slab pictures were taken with the slabs dry, indoors using my camera with flash. The close-up pictures were taken with my Dino-Lite digital microscope. If you want to see a lot more of the petrified wood pieces in m
  4. Below are some of the slabs/slices/limb casts of petrified wood from my collection. I'll post more pieces in latter replies. I especially like very colorful pieces and unusual pieces like Teredo bored pieces or pieces with fungus. I have hundreds of close-up pictures. If you would like to see close-up pictures of a particular piece, reply to this post with the number/numbers. If you want to see close-up pictures of some of the petrified wood pieces from this thread, check out my TFF thread at the below link: 1 Petrified Wood botryoidal agate go

    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.
  6. 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 w

    Petrified Wood?

    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

    Petrified Wood and ?

    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 a
  9. 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!
  10. A nice, little piece I found on my lunch break today. Found in Dona Ana county, New Mexico.

    Anomalies on Petrified log

    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 a

    Snails in Petrified Wood

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

    Petrified wood?

    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.
  15. 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
  16. Part two…looks like stems …Maybe, palm, cycad or fern? I guess another possibility is bone.. ?

    Pathologies (knots) in Petrified Wood

    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, nota

    Florida palm "wood"

    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. In the Early Pleistocene, about two million years ago, this bit of trunk was driftwood in the paleo Santa Fe River. The waterlogged wood sank to the bottom in a basin in the river channel. They became buried in a highly organic mud durin

    twig pathology

    From the album: PLANT, WOOD & MINERAL SPECIMENS

    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.

    Pet. Wood v. Coral v. Bone?

    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!

    Fossil or oxidized iron?

    Three 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

    Is this petrified wood

    Found this in my grandmas yard, 20 miles south of Springfield MO. If this is petrified wood, how should I properly clean it? Thank you

    Is this petrified bog wood?

    Hi, does anyone know if this is a petrified bog wood, the exposed part is really smooth. The 3 pictures are, the front which looks like it was long ago broke off from the main part, the bottom part was machine cut to expose it and the 3rd picture is the skin of this piece. Most of my items like this come from Estate sales from around 20 years ago so I think someone displayed this in their cabinet and needed a flat bottom. Thanks Dignrocks
