I found these in a forest in Germany. What are they? Petrified wood? Or just a rock/limonite? Thank you.

Here's something I found while rockhounding in my back yard in Richmond, VA. There are an abundance of agates in the area which is (I believe) geologically speaking, from the Cretaceous period. The striations on the broken side looked different from the other cracked quartz pieces from the area. They looked more like pores. It could be xylem from something botanical, but the rounded part makes it look like a joint. Also, on the rounded side, there is a part of it that looks like it might be where a tendon would attach to bone. There are numerous limestone caves in Virginia, so perhaps it is a stalactite? Or, maybe it's just another hunk o' quartz. I apologize for the omission of a metric ruler for scale, but I've included a US quarter for scale. (US Quarter 24.26 mm or 2.426 cm) Thanks for looking!

Just not sure what I'm looking at here. I found this while searching for metiorites in northern Arizona, specifically around Holbrook, Az. I'm sure someone here might have an answer for me. So thanks in advance. I also should mention I'm new to the site so please forgive me if I posted this wrong. Thanks. J.D.

Can someone please tell me if this is a small piece of petrified wood that I found today? Thank you.

Looking for guidance on what to collect today. 1/2 - Could this be pet wood or is there decent potential for fossils in this piece? I put bit of lichen to mark some areas I found interesting (potential marine fossils?). I could leave in place, peel off another layer, pour done water on it, or move on? 3- About same size as 1st one. Multiple trackways or insect burrows? For now, Collect or leave it? 4- hmmm, burrow or stem looking, but all pointed in same direction. 5/6-Not sure, but does not look weathering. AHH SNIKIES! I think that is poison oak & of course I was using my glove as a make do scale Gotta get to the sink! Thanks!

I was walking around an antique store here in Western NY this past weekend and found a ziplock bag of shells/coral for $7. The bag had a very nice Flame Helmet shell from the Caribbean, some pieces of recent beachworn coral, and this fossil wood section with polished end. Size 68mm x 40mm. The outer "bark" is chalcedony and the wood seems to me to be cypress or palm, possibly Eocene in age, I'm thinking US locality maybe Wyoming or ? I'm not an expert on petrified wood and will appreciate any help. Thanks

Seller doesn't mention teredo or termite but it looks like there's tunnels in the wood just left/superior of the center. Am I imagining it? Limb is 5.4" in diameter, per seller.

i found this is se ohio in a creek and i think it is petrified wood but i am not sure

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 golden calcite insect borings ostracods Eocene 50 MYA Green River Fm Blue Forest along Lake Gosiute Sweetwater County Wyoming 1.2 lbs 8.25 x6x.38 inches 2 Petrified Wood conifer Araucarioxylon arizonicum fungus Polyporites wardii early Permian late Triassic 295 to 201 MYA Chinle Fm northern Arizona 3.60 lbs 10.25x8.75x.5 inches 3 Petrified Wood Triassic 225 MYA Chinle Formation near Holbrook Arizona 745g 160 x200x12mm 4 Petrified Wood Seed Fern Rhexoxylon Triassic 220 MYA Ambilobe Madagascar 136g 3.75x2.50x.375 to .5 inches 5 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Acondromen Madagascar 575g 145mmx95mmx18mm 6 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Acondromen Madagascar 182g 4.25x3.5x.31 inches 7 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Acondromen Madagascar 201g 4.25x3.5x.375 inches 8 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Acondromen Madagascar155g 4.25x3x.375 inches 9 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Acondromen Madagascar157g 4.25x3.25x.375 inches 10 Teredo Bored Petrified Wood Slab Paleocene Epoch Canon Ball Formation North Dakota 2,150g 10.25x9x.625 inches 11 Petrified tree fern Tietea singularis Permian 275MYA Motuca Formation Parnaíba Basin in Filadélfia Tocantins Brazil 340 g 8 x 4.75 x.25 inches 12 Petrified Wood encased In Algae-Laurel Eocene Bridger Formation Blue Forest WY 1802g 9.5x7.75x.625 to .75 inches 13 Petrified Replacement Wood Eocene 34 to 40 MYA Clarno Formation Hampton Butte central Oregon 484g 7 x 5 x .44 inches 14 Petrified Wood Slab Woodworthia Triassic Chinle Formation Winslow AZ 408 g 5.5x4.25x.43 to.5 inches 15 Agate Petrified Wood Turkey 253g 6.25 X 3.25 X .31 inches 16 Petrified Wood Slab Cedar Miocene 15.5 MYA Wanapum Basalt Formation Saddle Mountain Washington 228g 5.5x4.25x.25 inches 17 Petrified Wood Slab Miocene 15.5 MYA Wanapum Basalt Formation Saddle Mountain Washington 361g 5.75x5x.44 inches 18 Petrified Shrinkwood Miocene Fleming Formation Live Oak County, Texas 176g 4.25x3.5x.375 inches 19 Yew Taxus sp. in Stromatolitic Algae Miocene Tonopah Nevada 3.25 x 2.5x.19 inches 20 Teredo Bored Petrified Driftwood Middle Miocene Saltos Shale Member Monterey Formation Santa Barbara Canyon near Cuyama CA 6 x 4x.625 inches 21 Petrified Wood Araucaria conifer Monkey Puzzle Tree Triassic Age 200 to 250 MYA Madagascar 572g 5.75x4x.7 inches 22 Hematite Replaced Teredo Bored Petrified Wood Eocene Yegua Formation or Cretaceous 40 to 50 MYA Lake Bryan TX 288g 7.25 x3x.44 inches 23 Petrified Wood Log Miocene Jarbridge Ryolite Formation Hubbard Basin Elko County Nevada 1061g 4.25x4x1.75 to 2.75 inches 24 Petrified Wood Triassic 225 MYA Chinle Formation Arizona 1186g 8.25x6.75x.625 inches 25 Petrified Wood Sycamore Platanus sp.

I found this at a Goodwill. Is this a bone? It looks like too much bark to be wood. The white part is far less dense compared to the center (darker area).

Hey guys, yet another I..D. request from new fossil spot, which is a deep creek bed which drains a diverse area ranging from Miocene to Jurassic. Wondering if this could be fossilized wood. Any thoughts?

I've searched the web and these forums before joining so I could post. Any input would be greatly appreciated. Appears as though it was once firewood. Shiny spot on "top" of specimen is water.

Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petrified wood--this came from the same group that sold me the fake shrimp. All help is appreciated.

I think I know this answer but is feasible that a piece of petrified (real) could have an end of it that was cut (doesn’t appear like a newcomer) it’s just a chopped off end in a perfect cut but not like a shear break and this piece is course like it wouldn’t break like that if it broke and it looks original. Not sure if that makes sense. It’s a whitish piece and came with a cross section slice of another piece that was with it. But I know to be petrified it was before mankind so couldn’t be cut back then?

More goodies from the same site as the sandstone nodules. Some of this looks like wood to me and one seems highly probable to be a bone fossil. Sorry no metric on the tape measure I'll look for a duel standard measure next time im in town.

I found lots of petrified wood in the lower part of the Miocene Chalk Canyon Formation north of Phoenix. The layer is mostly sandy and pumaceous. Does anyone know what the siliceous 1mm long elongated spheres are or how they formed? Could they be fecal pellets, fungi or other fossils. I have seen similar structures associated with California Miocene palm wood. @paleoflor Penny is 19 mm across.

Recent finds from Texas! Ammonites from the Goodland limestone, petrified wood and ice age stuff bank gravel of the Brazos river, either Beaumont or Lissie formations, or from a terrace deposit. The rib is mammoth/mastodon, the vertebra and hoof core bison, the antler is likely whitetail deer, and the teeth are horse and bison, with the small one I think a 3-toed horse based on the images I looked up.

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

Hey all! I haven’t posted in a long time but I was too excited about this. I absolutely love petrified wood. I love the colours, the rings, the detail! My wonderful husband bought me this AMAZING piece of petrified wood from a local rock shop. I took it home, gave it a bath and a good scrub. It’s green! Now I've heard about the chromium petrified wood from Arizona but I have NO idea where this one came from. It’s super heavy at 25.7lbs!! I absolutely adore this piece and even if it isn’t chromium wood, it’s definitely stunning!

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.

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

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?

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.

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.
