I found a nice exposure of the Arundel Clay recently. For those who don't know, the Arundel is an early Cretaceous unit known for it's dinosaur, plant, and other fossils, and is the only source of early Cretaceous dinosaurs east of the Mississippi River. I've been hitting the sites a fair bit over the past several weeks, finding a lot of really nice lignified and fossil wood and even some leaf imprints, amber, and what might be the imprint of a piece of bone or shell in a lump of clay. However, I recently found this specimen which has perplexed me. To start off; I'm fairly certain these are fossils. I just can't tell what of. They look similar to petrified wood, however I have not seen such fossilization of the other wood fossils from this site (or elsewhere from this unit). It appears to be silicified/agatized. I know dinosaur remains have been claimed to have been found near this site, including pieces of a leg bone that the finder originally mistook for wood (I can't verify if that's true or not, however). The Arundel is also well known as a dinosaur bearing unit, however I haven't heard/seen of agatized remains from it. After a quick search online it is possible, and my specimen at least bears a superficial resemblance to pieces of agatized bone from the Morrison Formation. Unfortunately my piece is too weathered to really see any features typical of bone in cross section, like a "sponge texture" or "webbing." Along the edge of the piece there is a bumpy, almost crystalline (for lack of a better word) texture, but nothing specific. I've included an image of a typical fossil wood specimen from this locality to compare this piece with the fossil wood.

For those who enjoy solitude and quiet away from large crowds of people, visiting the Blue Forest of Wyoming is probably one of the best choices. I personally love the most remote places possible, so I enjoy Blue Forest but those of you accustomed to living in or near a busy city may find it unsettling (or so I've been told). It can get busy during the summer, but overall it tends to be pretty quiet especially the further away from the road you go. I was able to visit the site last month and I found some very cool things. The drive out to the site really isn't too long in my opinion, but it's really not a site to spend 20 minutes at expecting to find a lot of big logs. Most of the really big logs have been found, so a lot of patience and persistence can (but won't always) pay off. Let me just say that if you plan to dig, it gets pretty warm out there. You'll need to take breaks throughout the day and rehydrate if you aren't acclimated to the dry heat. There was no wind when I was there and only occasionally would a few clouds dot across the sky so don't count on shade being there unless you bring a canopy with you. The first couple days started off a bit lackluster as far as digging was concerned. I wasn't finding much by digging, but when I surface collected I found a lot of nice small pieces. Different people have different methods of searching for petrified wood here. Some dig blindly, some probe and then dig, some witch for petrified wood, some probe existing holes, and some just surface collect. Each method has its merits. There has been a lot of digging here over the years, so the landscape is dotted with holes all over, some of which have been filled (if you dig here, please refill your holes so BLM doesn't try to shut the site down). I was finding a lot of nice small pieces on the surface where other people had been digging, but I was hopeful of digging up my own log. I'd heard about a few other people finding some small logs when I was there, but most said the same thing: they'd all disentegrated when they tried to remove them. The petrified wood here can be pretty delicate. It is encased in layers of algae, but extracting the wood from the algae can be difficult and often results in separation of the agate layer from the wood or even the log splintering completely.

I was wondering what tree this piece of petrified wood could have possibly come from and maybe a rough estimation of it’s age? It was found in Stockton, California by my grandfather. According to him, it was found in his backyard when they were first building the house and tearing up the ground in the backyard? He’s had it for a long time and recently gave it to me, since I really love fossils and Paleontology. I included some pictures with and without flash and the top and bottom of it. It’s 7 inches long. I also recently cleaned it, so it would be easier to identify it and see all of the details of it.

I found this in Mokelumne River in California. I’m not sure whether it is fossilized wood or just a river-worn rock? I was hoping someone could tell me which one it is and maybe let me know what parts of it are key to identifying whether it’s fossilized wood or a rock, so I can learn how to identify further specimens.

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, as I am exhausted from this semester of college (having to abruptly switch to an online format due to COVID-19). I’ll have to link other threads of my fossils and post pictures of my previous additions to my collection to this thread whenever I have the time!

It appears to me as a pyritized wood, it gave off the metallic sheen when it's under the light. Pyrite/marcasite are abundant at where I found this and it's from Kiowa formation (Albian). Kiowa formation is primarily an estuarine and shallow sea environment, fossilized wood and plants are occasionally found from there. I found it as a concretion but it crumbled into tiny pieces when I pulled it out of the ground, so this one is the largest and only piece I have now. Do you think it's a pyritized wood?

I wanted to try some new spots that are closer to home, so a family here was nice enough to take me out to their land near Dinosaur Provincial Park and allow me to surface collect. I only kept two things (wasted a good portion of the day searching for tyrannosaur teeth to no avail) but I did find some neat stuff so I thought I’d share. Please excuse the circling and the caption, those were for Instagram. Nice & green this time of year. Won’t look like that for long. Heres something I found a few times today; random pits of petrified wood just shattered. Here’s a good 10 inch chunk that I kept. More petrified wood. Dino bones. Most of them were broken and difficult to tell what they were, as the dinosaur park area bones usually are. Please excuse the circling. It was for Instagram. This was the largest bone I seen today, was over 2 feet long most likely but it was at an awkward place so I didn’t climb any higher to get close. Excuse the caption. This one was fairly large as well. This one I kept because it was one of the only good condition bones that wouldn’t require excavation. Hadrosaur toe bone. (thanks jpc for the help)

Hi! Thank you in advance for your responses. Whether this is anything or not, I'm thoroughly enjoying the learning process! Location Wyoming, near Cody (northeast). I found this while (unsuccessfully) searching for Geodes. This is from a large pile of transplanted rocks/earth which originated in the nearby hills. This particular pile is likely to have been originally 6-12 feet below the surface (I will be visiting that spot in a few days. I can upload a photo then for better context). WSGS data says the area is on the border of a Mesozoic and Cenozoic rock distribution. Interest I'm not sure what to make of this. It doesn't match the surrounding rock. I'm interested in the parallel "grains" throughout the piece, but confused by prominent grain-warping at a point near the outer edge. I really like the shell-like pattern of the coloration, but am curious about the inconsistent thickness at the rounded end. This is smooth to the touch (and sticky on the tongue...I licked it because the internet told me to...). This looks so much like a wood grain, but I see no rings in the grains, only coloration (though I understand not all woods exhibit rings?) I also have not found any images of petrified wood with a rounded end like this, so maybe weathering? Feels very solid (agatized?...that's a thing right?) Photos Link: Imgur Link to all photos

Hello, My son found this large piece of petrified wood on a ranch here in South Texas. It is a large piece and weighs about 70 LBS. The bark is a nice blue color. We noticed an unusual print on the wood and are hoping we can get help identifying it. The imprint is deep in the wood and appears to be a set of three. The wood was found laying flat just below dirt level with the print side up. I will include photos. Thank you for your feedback!!

So, me and my family bought a house. We are moving into it in June or July. While exploring the backyard and measuring for a garden, I scored a big fossil find. 5 LARGE pieces of petrified wood. Larger than I have ever found so far. They were partially buried in a spot where I was going to put some flowers. Legally, I can't take them until the deal closes, which we are certain will happen before we move in. As soon as the deal closes and I can get my hands on them, then I will post pictures. Apologies for keeping everyone waiting for the photos. Jared

I'm thinking petrified wood but maybe something else? Found in sandy area in central Mississippi.

Today I went fossil hunting near Rainbow Dam. Not expecting to find much besides the occasional broken bottle and rattle snake, I was surprised to stumble upon this cylindrical shaped piece of rock. Upon further inspection I decided that it was petrified wood. The area around rainbow dam is populated with loose shale and red sandstone. There are many exposed areas of rock here that I have yet to explore, but for the time being, I'll be focusing my attention on areas that I know have fossils. Back to the pet. wood, I haven't the slightest idea what formation it was part of, however, a helpful website provided me with the information that the fossils found in the area may have been that of the late cretaceous period. P.S. Forgive my cat in the last picture, the smell of my dinner was to much for her to resist. -DW Here's the website that provided me with my geological time frame. Cheers. -----> http://fossilspot.com/STATES/MT.HTM

Hi all, hope everyone is safe and healthy in these troubled times. What a great time to go over your collections and plan for the next trip. Found some info regarding fossils (Geo report) and petrified wood found near Stemwinder Park, Pickard Creek area between Princeton (fossil mecca) and Hedley B.C. Anyone know of the site? Example from someones find, undisclosed spot. We were going thru that area for work, now cancelled, so can't really justify the exploratory trip, but love to dream. . Just noticed the auctions! Must check here more often!! If you must foray out on rock trips, keep your adventures moderate! (I am a search and rescue first responder). Roweness

Hello everyone, During this time of pandemic lockdown (since March 17 here in france) I take a walk in the forest sometimes since I cant go to the beach to search for fossils, im in the area of calvados about 7 km from the coast and these are some of the things I found the other day walking along a dried river in the forest. I believe no.1 is a piece of petrified wood, it's heavy and have very well preserved details that look like wood. The other pieces I'm not sure, they are all heavy like rock and in some of them you can see rock. But I have no idea what they are. Size of the wood piece is 15 cm for scale. Thank you in advance for your help,

I haven't been on for a while. Reason is I'm getting ready for a move. I wanted to tell you all that while I was looking at a house, I found a 4.6 lb piece of petrified wood. The land owner said I could take it, to my surprise. The fossil is already pack with my other fossils. I'll upload a picture when I have a chance. May take a while.

Hello all! I am a new member, and this is my first post. Could I please have some help figuring out if these rocks are petrified wood? Most of them were found in a small Pennsylvanian stream. It looks like they are quartz, crystal quartz, but I am no expert. There should be about two pictures of each rock. Thanks for your help, and I have more pictures of different rocks if needed.

I found an odd piece of rock when my apartment has it's second floor garden soil removed. My neighbor said that it looks like petrified wood but I just want to make sure. Thanks.

Looking to have growths id present on late cretaceous wood. The growths are the scales present on the wood. They appear to have been growing between wood layers. Wood is partly carbonized and not fully mineralized. Wood was drift wood mixed in with baculites and scaphites. Fossil taken in situ from upper part of Kevin mb of Marias Fm in Montana.

Me and my brother were walking near a waterfall, when we both found this. I thought it was just a rock, but it has a very strange visible structure that makes me suspect it is a fossil, maybe its petrified wood encased in sandstone, but I am not sure. I am attaching 3 pictures of it. In the second picture, you see why I think it is petrified wood. In the other two, you see the structure of the rock I was talking about. What do you guys think?

Friends, I seem to collect lots of petrified wood in my nearly-every-weekend outings into the oil patch in the county where I live. Much of what is found are small little bits and pieces and a whole lot of it is really pretty. Some I will try to identify and those may earn their own topic entry, however, others are just nice little pieces that I cut up on my saw and will post the photographs here for y'all to look at. They are just too pretty to not share, you know? All those entered under this topic will be found near my home unless otherwise notated. Some of the petrified wood will have been found by a buddy of mine whose rock I cut up for him from time to time, and those will also be notated here. If no one minds, I probably won't put a scale on the specimens since all of them will be no longer than 4 1/2" on their longest side since that is as wide as my little rock saw can handle. As usual, feel free to comment. Some of this stuff might really challenge your ability to readily recognize what is or what isn't petrified wood.

My first find in a while. Been crazy because I am preparing to move to a new house. Here is how I found it. I was looking at a house with my mother. We were talking to the land owner about the house, when I saw a rock. Immediately my mind said, "petrified wood." I went over and looked at it. I was right. Petrified wood. I spoke to the land owner and said that he had petrified wood on his property. Without me asking to take it, he said that I could have it! SCORE!!!! Well, thats one way to find petrified wood! Jared

Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet.
