    Clarno Wood Dig

    While out wandering with friends in Clarno vicinity (the town, but probably also the formation; well away from the Palisades and on public land open to rockhounding and collection,) we came across some really vibrant, bright petrified wood, quite unusual for the area. The source tree looks like it's encased in a coarse ash or tuff, with a "shell" of harder material. The wood looks agatized but is still very brittle, too brittle for lapidary application but gorgeous for display; lot of opalized areas and mineralization. I tried to get back far enough to get a solid round but was unsuccessful (r
  2. I was walking along the many trails in the Sugar Land area near the Brazos River when I found a wonderful beach with many pieces of petrified wood. I'm very new to this world of fossils and rocks but I was quite intrigued by a piece of petrified wood with what I believed to be some fossilized sap (amber?). I was wondering if anyone could tell me more about this rock or the round piece of bone I found as well. Any input would be greatly appreciated! -Blxbrry
  3. This display contains 100+ specimens of the best petrified wood that I found, during more than a decade of fossil-hunting, in the Triassic age Newark Basin of southeastern Pennsylvania. The material is scarce. I have plenty more smaller pieces. The shelves dimensions are 6 feet x 5 feet x 1 foot.

    Unknown Fossil Please Help Identify

    Hi I have a fossil I found while exploring an area near Dubbo NSW australia. I taught it was just petrified wood until I cleaned it and notice on one end has colour and looks like it could have fish fins on the side. The length is 300mm and width is at its widest point 180mm. It was just sitting on side of a dirt track and also has another part to it which I will pick up next time I'm out that way again. Any help in identifying what I have here would be much appreciated as I wouldn't have a clue other than what I think it is. Thanks
  5. Hello TFF, I purchased this relatively inexpensive specimen at Mineralfest this past fall, and I was wondering if anyone could tell me more about it. The seller informed me it could possibly be from Madagascar, but was transparent in admitting that she couldn't confirm for sure. It was with other pieces of petrified wood that were brown, but I was drawn to this one due to the red hues. I think it's agatized, and it looks "glassy," although there are too many impurities to shine a cell phone light through it. One side is polished, and I put water on the rougher backside to show mor
  6. My interest is in current earth conditions that would be amenable to the creation of fossils, specifically petrified wood. I want to place wood in a position where it will be likely to form petrified wood at some point in the distant future for an artistic project. I am not a scientist, although I am reasonably scientifically literate. Nevertheless, there may be blind spots in my assumptions here. I would love to hear any thoughts that forum members might have. I would imagine a group of experienced fossil hunters might have a good idea of what past conditions have been good for fossilization.
  7. I'm interested in petrified wood for both the scientific value (wood where the cell structure is well preserved) and for the aesthetic value (mineralized with vivid colors and crystal shapes). Below are two petrified wood slabs from my collection. Black (carbon) and White (silica) Slab: Below are some close-up pictures taken with my digital microscope that show the wood structure in this black and white petrified slab: continued in next reply Marco Sr.
  8. Hi all! Brand new member here but long time geological fan and rockhounder. I am new to Texas and my job site has quite a bit of echinoid and bivalve fossils, and I was out rummaging around in the woods looking for some fossils when a “stone” on the soil surface stood out like a sore thumb to all the geological type base material in the area. In one little pocket in the under brush of cedar I noticed crystalline formations on material that was unique to the whole area. I am new to the whole geological formations but I was assuming it was in the glen rose formation type area. Anyone based on lo

    Petrified wood in this conglomerate?

    Any ideas as to what this might be? Thinking could be wood remnants, maybe petrified or partially so? Northwest PA, lots of glacial debris in area.

    Cut or not cut?

    I am debating whether to cut or grind smooth in several areas two pieces of Indonesian petrified wood with botryoidal chalcedony that I recently received. This is what I was supposed to have received: This is what I received (The seller removed most of the yellow surface agate.): I just don’t like the look of the pieces gouged and scratched so I want to remove as much of the damaged areas as possible and maybe grind smooth other areas. First Question: Should I try to cut the piec

    Plant Cast or Animal Fossil?

    Good Morning, I came across this interesting piece about 3' below-grade in Live Oak County, Texas. I've managed to dissolve some of the 'caliche' with 5% vinegar to clean this up a bit. There is pet wood and the occasional Columbian Mammoth molar in the same vicinity as this piece was found. It is relatively light for it's size, compared to pet wood. Looking for anyone who can offer an opinion/advice on this piece.

    Unidentified Petrified Object

    There are no pictures of this roll shaped rock before the rock crusher. It was approximately 5 inches long and 2.75 inches diameter cut off square on both ends. it had a noticeable double 1/2 spiral ripple in its length. We don't know where it came from. It was found in 1976 in a newly purchased farm house in Michigan.

    My “Mesozoic Park”

    Well, I figured that I should start a member’s collection. Sorry for my absence, I was busy with college classes. I did great this semester, and I even won a student leadership award! With that being said, I’m gonna start my collection off with a piece that I acquired for my birthday! My 22nd Birthday is tomorrow (June 14th), and I was strapped for money. My father and grandmother chipped in, and helped me acquire this chromium woodworthia piece from a local rock shop that I frequent! It’s from Arizona, and it only cost $60 USD! I’ll try to be active here whenever I can
  14. Hello. I have opalized wood for trading. Age - Paleogene. There are Teredo mollusc passages ranging in size from 6 to 10 mm, filled with cemented opal sand, less often with chalcedony. Insect coprolites are also found. There is a sample of a solid section with annual rings (ground, but not polished). If you are interested in such samples, please do not hesitate and contact us in a personal. Have a nice day.
  15. This was found on the banks of a river bed around Locust Fork River in Blount County Alabama
  16. Hello, My son and I were walking on a local trail and he found this. We are trying determine if is a bone, petrified wood or something else. We are complete novices, so please forgive us if it's nothing. Thanks in advance for your help.
  17. I dug up a log in my backyard, I would love to know if it is petrified wood.
  18. Hi all! I made one of the the personal coolest discoveries of mine yet - while hunting for petrified wood in tiny, tiny stream on the catahoula formation I found a chip of petrified (palm, most likely) that is completely composed of a translucent mineral, perhaps quartz? I'm curious as to what mineral this piece may have fossilized in. Furthermore, is this a particularly special find? I'm a newbie, so just because it's a first for me doesn't mean it's uncommon. Here are some photos, for reference: and the other side: here it is wet, and held up to the s

    Petrified Wood?

    Ok, this is my first post, and I think I read the rules right, so if I didn't do anything right just let me know and I'll fix it. So I bought this boulder off a guy. It's about 3 ft long, 2 ft wide, and weighs about 200 lb. The guy told me that it probably came from Kansas or Minnesota. He couldn't remember very well. But I am in Lincoln Nebraska so I suspect it's probably Kansas. I asked a guy for information about it here in Lincoln. Specifically I asked him if this was a petrified log and if the big lump on the side was a concretion. He said that "This is a weat

    Petrified Wood ID and Care

    Good Evening All, I'm new to this forum and this is my first post. I was hoping someone could assist me in identifying the type of petrified wood I found in South Texas and the easiest way to remove the white minerals around it (providing I even should be removing the minerals around it). There were several pieces found about 4' below-ground on the edge of a crevasse where water was carving out the soil. I am tempted to return with an excavator to locate more of it but will hold off in the meantime. An early thanks to anyone who can reply and give me some guidance.

    Petrified Wood Identification

    I would rather identify most any fossil other than petrified wood! Not a botanist, so when I referred to my ancient copies of Gems & Mineral magazines from March to August of 1960 and read Virginia Page's "How to Identify Fossil Wood", I got lost in a hurry. I'm trying to identify wood from the Cretaceous in Southeast Missouri at Crowley's Ridge. I have a polished cross-section image and am hoping someone can identify it for my fossil database. I don't have a longitudinal section, but could do one if that is necessary.
  22. After a trip to Venice Beach, Florida, I'm having trouble with identifying 2 fossils found onshore. The first is something I initially thought was a well worn micro shark tooth, but on closer inspection am having doubts. There is also a piece of what looks like petrified wood. Perhaps pine? Any help or resources would be appreciated. Thanks!
  23. Drove south of San Antonio to Tilden, Texas to check out our favorite petrified wood location. My wife and I found some decent pieces. Some are very “tumbled” from the creek but other pieces have retained their wood characteristics. Bonus is that I found a scraper type tool that is probably as perfect as a piece I have ever found. Last trip of 2020.

    Calling all Petrified wood experts

    Hello everyone, Merry Christmas! I have a few hunks of petrified wood I want confirmed, all three were found in the Denver area. I'm expecting that they're just all different examples of agatized petrified wood, but I want to make sure. The first two have been in my backyard since we moved here, the third my uncle found in his yard and gave to us. My question is, if they're all agatized petrified wood, how come they all look so different? Thanks in advance for any help you can provide!
  25. Hello, I found this piece of petrified wood last month. It comes from Middle Eocene (37-35 million years old) terrestrial sediments, from the Yegua Formation of eastern Texas. What I love about this piece, is that it is a piece from the bark of the tree. The tree that this specimen belonged to, was some kind of hardwood species (angiosperm), probably something like maple or birch, judging by the structure of the wood in one of the endcuts/endgrains. What is so special about this piece, is that the bark side is covered in some sort of carbon film material, which gives it a nice,
