  1. JUNK or petrified wood/bone?

    Hello first time poster. Found as is (not encrusted or buried) along the Whiskey Bridge outcrop in Bryan, TX, along the Brazos river. 4cm in length, about 1.5-1.0cm in diameter. Thought it was petrified wood but a hole at the cross section makes it look like a bone or antler? Surface pattern looks like antler. Has some weight to it and makes a rock like sound when put on a table or something.
  2. I recently purchased this along with a number of other fossils. The only drawback was that there was absolutely no information to be had on them, but I jumped at it since it was such a good deal. Now I'm hoping that somebody out there may have an idea what type of wood this is and where it might come from.
  3. Large fossil "petrified" wood

    And lastly the large, 13lb section of wood, found not associated with any layers- found in the little blue river of Kansas City last week. very dense for its size. I understand this may not be speciated but pretty none-the-less! And not to stri the pot, but I've read some articles stating that mineralization can happen very fast, and some "petrified wood" could only be a hundred years old or less. I would presume there are so many factors that enter into mineralization of wood that only some techniques and carbon dating could help define age? Thanks for looking! Bone
  4. Hi All, This specimen is from a pile of tumbled rocks, no provenance. My best is guess that is Rhynie chert with sections of silicified fungus or early plants. However, it might just look similar. No clear cellular structures are visible. The circles are 13 and 4 mm in diameter. An expert opinion would be much appreciated. Thanks in advance!
  5. Petrified wood burl??

  6. Amber vein in Pseudomorph after pet. wood?

    I inherited this specimen among others when my grandmother passed away. I believe it is agate chalcedony pseudomorph after wood because there is what appears to be a vein of Amber in and spilling down the exterior. I have all kinds of photos, but am having issues uploading most due to size.
  7. Hello everyone With the covid 19 going on I can't take a couple items and have them check at Museum I have what I believe to be a lemon Light shining through fossil
  8. Is this a mushroom?

  9. petrified wood collection .

    This is a part of my petrified wood collection . any idea about the time required for wood to be agatized like that . thanks for looking .
  10. Marine life?

    I'm not sure what to make of this. Maybe it's some marine life? Or something petrified? Idk. I've had it for a while. It was found in Venice Florida. Thanks in advance
  11. Hi, Is this real petrified wood? Never seen blue in wood before? I also haven’t seen any petrified wood faked. Seller seems legit and the information he/she provided about age and area check out. Any help appreciated. Travis
  12. petrified wood ID help

    I found these stones among stones of the digging residue of the suez canal . hope to know your opinion and encouragement as this is a very new start .
  13. This past weekend I was able to enjoy a rare February day of sunshine and temperatures above 50-degrees F (10-degrees C) in a vast expanse of public land owned by the U.S. government and in care of the Bureau of Land Management located in northwestern New Mexico. The area where I ventured is Upper Cretaceous though I am not sure of any period beyond that general age. Of the fossil related items I ran across, the first two photos show some petrified wood from a ground level stump. I noted some unfamiliar calcite patterns that were vaguely diamond shaped. The second photo shows an outline of these patterns and my rock hammer is there as an 11-inch (28-centimeter) scale. A friend of mine who knows considerably more than I do about fossilized plant life informed me this was once a cypress tree. The next two photographs shows a large surprise sticking out from under a mound of soil. Since this was BLM land, the bone remains in situ since collection is verboten. I have no further information on the bone. As a late addition while I can still edit this post, I can't believe I forgot about the petrified palm wood I found. I got it cut up and have attached a photo of it here. One thing that was pretty cool about the palm wood, and hopefully it is visible if you enlarge the photo, is that the vascular bundles (the dots you see all over the wood) due to compression of the wood prior to fossilization aren't really round but have been distorted and shaped like half-moons. This is commonly seen in other specimens collected in my area of the country and I'm sure elsewhere.
  14. Found this here in western Colorado I have done some looking online closest thing i can find is fossil/petrified palm wood it would be from the Niobrara Formation, Smoky Hill Member and is Upper/Late Cretaceous. What do you guys think? Did a quick polish too quick as you can see all the scratches haha Thanks anyone that can help

  20. Petrified piece of a boat?

    Need help identifying this
  21. Petrified Termite or ant colony

    This was near wear (as best I can tell) a tree was struck by lightning or burnt out at least 40 years ago. It is rock but I’ve soaked it but am scared to use vinegar? Should I chance it? Any idea what it is? It’s 5 inches in Links 4 inches high 3 inches deep this is a close-up picture
  22. What kind of tree?

    I have a number of nice pieces of petrified wood found in Central MS area while hunting with MS. Gem & Mineral club 20 years ago. Can anyone tell me what tree this would have been from? Hope the pictures are clear enough to help. Thanks, Deb (White Feather)
  23. Petrified Fungus?

    Hello everyone, I'm new to this forum, but I always lurked here without an account and learned a lot, so I made one to become part of the community since I collect and study fossils as a hobby. Now for the piece mentioned on the title, would you be able to help me figure what kind of fossil (or even if its one) is this? The structure reminds me of some fungus, like a polypore, but I cant figure what kind it is or if its an igneous rock or some kind of wood. I know some bracket fungus when dry can become really hard. Unfortunaly I dont have the item in my hands right now, as its from an auction that I won and I'm still going to retrieve it from the owner. All he knows is that it came from an american geologist collection in California and that it is really really old. It has 19 cm, not sure about the weigh tho. Thanks!
  24. Tree Fossil?

    Found this piece of sandstone in Sullivan Co., PA. It comes from either the Huntley Mtn. Fm. (Mississippian/Devonian) or the Burgoon Ss. (Mississippian). What could have made these concentric rings? They go through the rock perpendicular to bedding. It's odd that the center is mostly round but further out is more square. Could it be a tree fossil? That is the only thing I can think of.
