  1. Hello everyone, A while back I was gifted this fairly large piece of pet wood from Arizona. I don't really know what I can do with it as I don't have any equipment to polish or cut rocks like this. I was wondering if any TFF members have such equipment, and if they did how much it would cost to either polish this piece at one or both ends or alternatively, slab it and polish some of the slabs. I don't know if it would be worth the time or money to do so, I am just trying to see what I can do with a piece like this. Thank you very much for any help, Misha
  2. Found this yesterday in Texas (Gulf coast plains area). Looked like petrified wood at first but now I'm not sure. Either end is very pourous and looks a lot like the inside of a bone.
  3. Hi all, We were in the Yellow Cat/Poison Strip area this summer and came across what we think might be a dinosaur bone in the Poison Strip sandstone layer. We also found agate/jasper. Trouble is, the “bone” is an unusual shape and the petrified wood for the area supposedly has lost its grain structure, so I’m not sure what to say. Wondering if anyone else can chime in about these? thanks, Lloyd
  4. We visited Yellow Cat Flats/Poison Strip and went fossil hunting. At the time, we thought we found petrified wood (there, the wood doesn't show any grain so tricky) and dinosaur bones, but now we're just unsure. We posted in the ID section before posting this video and reached out to others, but it's tricky. If you have any ideas, please let us know, and posting below the video on youtube will help others to learn as well (outside this knowledgeable forum). best wishes, Lloyd

    Petrified wood

    Hello all, I feel like this is a stretch but I'm wondering if anyone can help ID this petrified wood slab based on its appearance? I got this back when I wasn't keen on age/locality so unfortunately don't have any other information. Its diameter is about 100-120mm across. I know some types of petrified wood such as the Arizona rainbow petrified wood or Palm wood have characteristic appearances so perhaps this one looks like something?

    Is this a fossil?

    My daughter found this while on a hike through a creek bed. The top of the bank was roughly 20ft high. Tom Green county, Texas. There were a couple of pieces of petrified wood in the same area. I've seen plenty of animal bones, it has that texture, but the shape is peculiar.

    Great grandfathers rocks

    So I’ve got a few questions all at once. Over the years I’ve inherited a number of my great grandfathers rocks (he was also into paleontology and geology) but I’m not sure what they all are. I’m guessing 1 is some sort of mineral, not a fossil. It, along with 2 and 4, were found digging the foundation of his home in south Charleston, WV. I feel like 2 might be petrified wood, but if it is I’m very curious about the side that’s black and very crystallized. 3 is from Seneca rocks in WV and I feel like must be a fossil but I really don’t know what. 4 again looks like petrified wood to me, and 5 for a complete change of geography, is from Washington state, somewhere at the beach (as vague as that is). I imagine it’s just some sort of mineral inclusion in an ocean tumbled rock, but thought I’d ask. My last question is geology related so apologies but I don’t wanna have to go make a bunch of new friends on some geology board so I had hoped one of you would be able to help me. Great grandfather hand made this board of rocks and minerals but it’s missing alabaster and lepidolite. Anyone have any idea where I might acquire single, small samples of both of these minerals so that I might complete the set? As always many thanks for taking the time.

    Any idea?

    We have dug up this when repiling our house. Not sure what it is?

    Petrified wood with amber?

    I found these two pieces on a gravel road along with bucket loads of other petrified wood. It was brought in with other large rock and put on a dirt road near my home. (West Monroe, Louisiana) Therefore, I’m not sure of the exact location from which this came. I was wondering if this was amber that had been petrified with the wood somehow? If it’s not amber, any suggestions as to what it is? Second piece

    Looking for ID

    Hello all! We just had a family member pass, and among the items we found, are several pieces like this one. Not sure of this one is petrified wood or some sort of fossilized tusk. There are a few more with a very similar "curvature" to them, like this one below. Beer can for size comparison. Any help in identifying them is greatly appreciated. Thanks!
  11. Here's an unusual bit of petrified wood. This is from the Nacimiento Mine near Cuba, New Mexico. The mine has been closed for some time but occasionally collectors are allowed in. (The land has reverted to the Forest Service, which is cleaning up the aftermath of an abortive attempt to extract copper using sulfuric acid leaching.) The mine is a huge point bar deposit of wood in the Shinarump Formation (Triassic) that was permineralized with copper minerals. The black here is mostly chalcocite, copper sulfide, which in a few spots has been oxidized to blue or green azurite or hematite. At the mine itself, you see black fragments of the chalcocite-mineralized wood with lots of blue-green staining around it, as well as occasional wood fragments that were silicified rather than copper mineralized. At left is a chunk that was permineralized with copper; at right is a twig that is more conventional silica permineralization. The difference seems to be in the original state of the wood. It appears much of the wood was partially burned, and the charcoal was more likely to permineralize with copper minerals than silica. Cool as copper permineralization is, the fact that it's charcoal rather than pristine wood means this is of more mineralogical interest than paleontological. Still, though y'all might enjoy.

    Petrified wood find in Houston

    Just joined and this is my first post. I’m hoping to learn more about this find in northwest Houston. It was on a site with imported fill material, so it could have come from a different area nearby and at a different depth. It was encased in white/light gray clay with many 1-2mm round river pebbles embedded in the “bark”. I’m interested to know mostly if the outer section being different than the inner section is a normal formation, and additional information will be appreciated. Thanks.
  13. Hey guys new to the forum! I have a piece of petrified wood that looks to have both copal and amber veins in it. I know how almost impossibly rare this can be but this has passed every test for amber that could be done outside of a lab. I am getting it verified in a few days. Would like to get the communities opinions on this piece. Thanks.

    Starfish and leaves

    I found a few interesting things at a road cut near Brady TX that I had went to with the Austin Paleontological society. I found a layer that had about 140 starfish and in the same area some of the layers had pieces of petrified wood and what looks like tiny leaves. Any info is appreciated Thanks
  15. I do not have a large fossil/rock collection, but what I do have I am proud of. This is my rarest piece I have. It is a piece of petrified wood from The Allan Hills, Antarctica. During the 2001-02 summer I was fortunate enough to land a job as a janitor at McMurdo and was night janitor at Crary Science Lab. So a guy I know had went out to do work in the area and brought back samples. He was like, "you want some petrified wood?" I happily took it not knowing at the time how rare and hard this was to get. Also, this is a rather large piece, being about the size of the palm of my hand and while we moved it split along a weak plane falling into two pieces. It was ok, because I can display it better now. I have some other rocks from Antarctica I will show at some point. Since my collection is small I will spread it out over time.
  16. I've found a lot of petrified wood around town and over the summer I cut of slices out of a few. I don't have the ability to polish them, so I put on a coating of nail polish. I then decided to put them under a microscope. I don't get a lot of magnification, just about 45x. This piece has some nice coloration and pockets in it, but it's even more interesting when you zoom in. I can't tell exactly what these dots are. They only look like this in a few regions on this slice, in other places they're empty as you can see to the right. Here's a more representative view. Unfortunately this is a much magnification as I can get. This next piece is one I posted recently. You can see lines going vertically across the screen, and occasionally there are black dots between the lines. I have no idea what those are. It's probably time to brush up on my plant biology. The structures are more apparent in the lighter sections.
  17. Texas Panhandle area. Found a lot of petrified wood, and realized one of the pieces looked like bone! Now I'm not sure about some of the others. I don't know anything about this stuff, so please help! Thanks in advance! :laugh: :laugh: :laugh: The first one I'm pretty sure is bone - it broke in two pieces in my bag unfortunately
  18. To be completely honest, this wasn't one trip, but rather a few trips I made in the summer to a local collecting spot that I love. I live here in CStat so I could go as often as I like. After I first heard that there's a lot of petrified wood in College Station, I felt like I couldn't even think of anywhere to go collecting. There's so much private land out here and everything else is paved. Eventually I found a place that is not private land, is not picked over, and is not illegal to collect from. These are just a few of my finds, I have probably 50lbs of petrified wood. Once I realized how much of it there was, I stopped taking everything and even put some pieces back when I thought I had too much. My two favorite finds are a small piece that still had bark attached (at least, that's what I think it is). There's a clear circular part that is smooth, then a rougher layer on top of that. I've also found some pretty woody looking pieces. Then there's the "moccasin". And finally, my favorite piece of all. I found this piece just sitting in a creek, looking beautiful. It actually looks almost the same when wet or dry.

    Black petrified wood?

    Hello to all! I'm an avid sea glass collector here on Cape Cod and have been collecting it for almost a decade on a beach hugely covered by rocks - which I've pretty well ignored until this recently caught my eye. I picked it up thinking it was just an interesting composite rock but was completely stumped when I saw the wood grain section as well. After some quick internet research I was so amazed to find it seemed to be petrified wood. I think it's safe to say that I probably haven't given such a thing a second thought since a grade school science class so had the contrast in the piece hadn't been so pronounced I never ever would've even thought to look for it. I still have a huge amount to learn about the identification of classifications, but am I looking at an example of black petrified wood? The feel of it is extremely smooth. The last two photos are of a piece I found the other day with some beautiful orange & red transparencies when aiming a flashlight behind it. It would seem like a pretty straight forward piece of petrified wood but perhaps I'm wrong? Ever since that day I've been collecting like mad but I really want to education myself about identifying petrified wood vs agates or other rocks, so if anybody could recommend any books for a reference guide it would be much appreciated. Thanks for your insights. , Julie

    Petrified Wood. Is it burned wood?

    Hey there! I was recently given this beautiful chunk of petrified wood. I have found pieces through the years but this is the first I've ever seen with crystals which has intrigued me to learn about them more. I was wondering if this piece is possibly burned wood? It came from somewhere around the Mesa Arizona area I think I'm still trying to confirm that but definitely Arizona. Other then knowing it is petrified wood I would like to hear any info anyone may can give about it.

    Texas Gulf Coast Beach Find

    At first I thought it was petrified wood but it has some odd molar like shapes another side I've never seen before in a tree or in petrified wood. Found washed up on the beach at Matagorda Island, Texas, near the lighthouse. It feels very heavy for it's size like the density of petrified wood.

    Is This Petrified Wood?

    I found this mystery rock on a lake shore in central Minnesota. Is it petrified wood? How does one tell whether or not a rock is petrified wood? Thanks for the help!
