  1. Fossil coral,moss?, bryozoan

    I picked this up at the flea market. He told me it was petrified moss...which I dont think it is. Im thinking coral but I wasn't able to find the answer after some research. Its from Arizona and was collected in 1968 and its jurassic in age. Pretty cool fossil.
  2. Does anyone know if this could be bone or petrified wood?
  3. These objects appear to be fossilized bones. Tongue test: (yuck) ahh seems sticky. Lighter test: does not burn. What are some other tests I can do from home to confirm these are 1. Bones 2. Fossilized? The objects are heavily mineralized. Examining the objects several of the larger objects have a circular protrusion harder and sharp in their top middle and bottom middle. The material protruding nipple appears to be more heavily mineralized than the majority of surface material. If these are bones can anyone identify them? Found in western Pennsylvania in an upland area eroding out of a hill into a stream. The stream is a headwater of the Potomac River. A Bovid astragalus was also found within inches (the astragalus dies not appear to be fossilized). In total 15 possible petrified bones were found on the surface within 1 meter of each other. In the center of the objects was a large flat rectangular block of limestone. My uninformed supposition is this was a fire pit and bone marrow extraction spot over 10,000 years ago. I’m looking for confirmation the large objects are indeed fossilized bones. If they are I will seek advice about carbon dating.
  4. Help ID of Petrified plant/wood?

    This piece was found in the same stream bed that I have collected petrified wood from. The area in south of the Dinosaur Park in Laurel MD, the stream runs though College Park MD and is close to areas where foot prints of Cretaceous dinosaurs have been found.
  5. 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.
  6. 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.
  7. 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
  8. 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!
  9. Petrified wood burl??

  10. 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.
  11. 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
  12. Is this a mushroom?

    Found this raking river rocks?
  13. 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 .
  14. 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
  15. 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
  16. 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 .
  17. 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.
  18. 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

    Need help identifying this
  25. 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
