While I am more knowledgeable about fossils than when I joined, this thing is confusing me. It is porous with fine holes and appears to be bone, but it could be wood. Any clues?

My girlfriend, Valerie and I planned a two week trip to New Mexico and Colorado to visit friends, see scenery, and attend the Peach Festival in Palisades. Of course fossil collecting would be a part of it. I spent a full day with PFOOLEY outside Albuquerque in the Puerco Valley hunting ammonites in the Carlile Member of the Upper Cretaceous Mancos Shale.

I had purchased some petrified wood that was cut into book ends. The blade marks were quite rough. After some effort on my flat lap, to my amazement this half had an image of a man and a dog. I named it Elvis and the Hound Dog. The other half was all black. The piece originated from Sweet Home, OR. I think it is quite the find. I was wondering if others have found pictures in their fossils/rocks. I know picture stone is known for patterns, but images are on another level.

Found this sticking out of a creek bed. The smaller piece was directly under the larger one, but it doesn't appear to have broken off. It just has a similar structure. I can't figure out if it's wood, coral, tooth, horn, etc. We have a little of each around here (just north of Austin, TX) but mostly marine fossils. In 5 years I haven't come across one that looked like this though. Closest thing to the interior structure I've found is bison tooth. Any ideas?

Hello, So, I am doing an interesting experiment involving Petrified Wood. I am taking petrified wood and looking at it under a magnifier. I am also taking non fossilized dead wood and looking at it under a magnifier Basically, I am comparing Petrified wood to living wood. I am doing this to see the similarities and the differences between living plants and plant fossils. I am a gardener, its another hobby of mine, and I am curious about the differences and similarities. I have some interesting data so far. According to my observations, there are not a lot of differences between the Petrified wood and the Living wood as far as the grain direction and the rings go. I used a magnifier setting to look at the grains. It may look weird, but it was the best way for me to get an idea of what the grains and rings looked like. Attached are the pictures. I also noticed that the grains and rings are farther apart in the petrified wood. There may be a reason for that. I am looking into it. I just wanted to share this experiment. If anyone has input about the experiment or additional data, please feel free to post it. If you want color photos, I will get them. Jared

Okay so now that I have found a group of individuals to help me identify.... I would love to know what find of petrified wood I have collected.. species and mineralization would be helpful. I have stuff that I can't find online. I'll start with the first two that I can't even tell if they are wood or not... All help is incredibly appreciated. Found these two river tumbled pieces south of Green River, Utah. Jurassic I think? Very different from everything else in the field.. Looks agatized? Thank you! Trenton

Finally gave up and had to ask questions. These are from southeastern PA, found in a creek. There's quite a bit of chalcedony mixed with what looks like wood, do we have petrified wood here in PA? Some looks a lot like bark although a few seem to be just sedimentary rock ( not posted ). There's also a lot of conglomerate around here, not incredibly interesting then picked up a piece I've never come across before. It's around 4", the other only just over 1" There's no debris on it, the random pieces in the chalcedony are as solid as the rest. If it isn't wood is it something else with organic origins? Then there's this. Piece of pine cone, along the right bottom edge? What is the long piece at the top? Most conglomerate around here is composed of agate and quartz, these are brand new to me. There are quite a few more like the top images, only one like the third. If these don't qualify as fossils, sorry to have posted them in a fossil forum!

Hello, So, I was looking in my collection, and I found this. Its the first fossil I ever found. Found it in my backyard in Nampa, Idaho. I was looking at it today, and I was beginning to wonder if it really was petrified wood. I mean, it didnt look that much like it. It looks more like a crystal. While I was getting a picture under my magnifier, I discovered that it had lines like wood grains going in one direction. I never noticed them. The thing is you can only see these lines under a magnifier at maximum magnification. They are that faint. I have two questions. First off, is this really petrified wood? Second, if it is, why is it so black? I have never seen petrified wood this color. Any help will be appreciated, Jared

Hello, So, I've mentioned several times a rock that I found at my old house and found fossils in. Today, I can now tell you that I'm finally done looking at and going through the Rock. In total, inside the rock, I found two gastropod shells, seven bones that were most likely from a fish, and a whole lot of petrified wood. It's amazing that all this was inside a small 3 to 5 pound rock! Pictures will be coming shortly. I can't really do it from my phone, and my laptop went missing. I'm trying to find it. As soon as I get the pictures, I will post them. Jared

This small specimen was said to be a naturally polished petrified wood found in a river at Liaoning, China. I cannot find any tree rings or wood features. The surface does however has some irregular patterns. Do you think this is simply a geological specimen or a fossil? It measures 6x4x3cm.

Here is a Rosary that I made of fossils for an elderly Dominican Sister friend. The cross is late-Triassic petrified wood from the Chinle Group of New Mexico. Jesus is carved from wood from a 50-ft log, with a diameter of nearly 5 ft, that was dredged from a depth of 40 ft in river-deposited sand and gravel in Indiana. A sample from the outer part of the log was radiocarbon dated at 1,920 +/- 60 years BP. The tree had over 300 rings, so would have been alive at the time of Jesus. The Halo is a bivalve from the Plio-Pleistocene of Florida. The center-piece is a Stropheodonta demissa brachiopod from the Middle Devonian of Ohio The "Our Fathers" are Platystrophia ponderosa brachiopods from the Late Ordovician of Kentucky. The decades are matrix with inclusions of the calcareous marine alga formerly known as "Solenopora" (nom. Illeg.) from the late Ordovician of Kentucky. The second photo has an American quarter dollar coin for scale. Suffice it to say, this is a relatively large Rosary. Thanks for looking.

Rice Northwest Museum of Rocks and Minerals - Oregon
Brett Breakin' Rocks posted a topic in A Trip to the Museum
Well, it finally happened ... made the time to stop off this summer at the Rice Museum of Rocks and Minerals in Oregon. Specifically in Hillsboro, Oregon. And wow, WOW .. what a collection !! One that rivals or equals a good number of natural history museums that I have visited. The most impressive was the extensive collection of petrified wood. Some of the slabs could have easily swallowed me. The minerals, as you will see were also quite impressive. Outside there was a seeded rock pile that the kids could dig around in and save their treasures for a minimal fee .. 1.00/lb. The first fist-sized mineral was free. Palm wood from Texas ... Some fantastic corals too ...

I came into a rock and mineral shop in Northern California and looked around. I saw this on display and bought a few pieces. Is this actually petrified wood struck by lightning? Does anybody know the provenance of this fossil (it wasn't specified). Thanks.

Hi everyone, I enjoy finding agates and fossils along eroding sections of Crowley's Ridge, a ridge of glacial deposits that runs through eastern Arkansas into southeastern Missouri. I appreciate your help ID'ing this chunk of something. As I recall, it's around 15cm long, around 7cm wide. I'll measure it tonight. Most of the petrified wood I find along the ridge is very dark: predominant colors are blacks, browns, and dark reds. I'll include a couple of samples in a picture below Both of those specimens are 7-10cm across. Both look a shade darker in "person." This is light to medium grey (just a shade lighter than it appears in the pics). The growth/deposit rings look interesting. Any thoughts? I appreciate all information/opinions on the grey chunk or the two smaller pieces.

Help Identify. Petrified Wood? Petrified Cactus? Something else?
SCSeaGal15 posted a topic in Fossil ID
Found this antiquing. Was only marked "petrified rock"..It is black & charcoal gray in color with a vertical ribbed texture and some rounded ends. Measures 6.5" tall x 5.5" x 4" and weighs 8lbs 1.1 oz. Is it petrified wood ? Petrified cactus? Or something else? It's only letting me upload 1 photo. Took pics with phone and guess their too big. Will try to post more.

small chunk of petrified wood ... found this strange looking chunk of petrified wood in the gravel drive west of Houston from gravel from the Brazos River. It is about 2 1/2 inches by 2 inches any ideas on the type of wood?
-
1 inch thick and about 1 1/2 inch wide found in gravel from the Brazos river this specimen has a basket weave type grain any ideas of the type of wood this was? on first glance I thought it was a wear pattern but under the microscopic camera it looks similar to a basket weave pattern.

Found this in the Peace River. In the pictures it looks like a wet piece of wood. It’s definitely fossilized. I’m thinking petrified wood but the color doesn’t look like any prices I’ve seen before? Also, what type of sharks are the last two teeth. I think one of them might be a small meg. If it is, it’s my first meg!!!!
-
Good Afternoon, I found this in a washout in southern Brazos County in Texas. The holes look to me like woodpecker or sapsucker marks that are common to that area, but I have found lots of petrified wood in that area and none of it had holes like this. I have also read that several other things could be responsible for holes in petrified wood. I would appreciate any comments or definite identification of how these holes were made. Thanks!

I've been planning a fossil hunting outing with my son for the next week or two (weather permitting), and yesterday my wife kindly suggested that I scout out the site before I take our 8 year old on a fossil hunting trip deep into the woods where no cell phones reach. So, when today turned out to be mostly sunny and pleasant, I hopped in the car and headed to a location that sounded promising on old geologic maps/reports (by Rau in the 1950s-60s, to be precise). And it turns out that (as always) my wife was correct -- the logging company who owns the land has apparently erected a gate blocking vehicle access to the road I was planning to use to get to the site, which was not on any topo maps including the relatively recent FS Topo that encompasses this area. Their sign said it was fine to hike in as long as I didn't remove any "special forestry products." Pretty sure fossils don't qualify! I was originally planning to start with what Rau called "Tl-3," one of the lower (geologically) members of the formation, but in light of having to hike instead of drive, I opted for a closer member, Tl-5. After a short walk on the road, I struck out for the stream I was targeting through the woods. This is the part where I'm pretty sure my son would not be capable of pushing through the underbrush on steep and soggy stream banks, so I'll have to find another site for next time, preferably within easy walking distance of a logging road I'm allowed to drive on. When I reached the first exposure of the formation, I could see clear evidence that I wasn't the first person to visit this site (no surprise there), in the form of piles of debris at the base of the bank and a few clear empty spherical gaps in the outcrop. But, I had no trouble finding many small concretions (shells or nothing, I assume?), one large misshapen one (maybe not even a proper concretion?), and one nice looking one that I assume contains a crab, so I suspect no one had been there since the most recent tree-falls and rockslides. I scrambled up, down and along the bank for about 45 minutes, collecting any concretions or fossils I saw either exposed or lose, but did not attempt to expose anything new (maybe next time!). I found a very nice piece of fossilized wood in the debris pile, too, which I can only assume previous visitors to the site mistook for ordinary wood. I am tired and dirty and need to do some household chores, so I will save the whacking of concretions for another day, and probably not do the (likely) crab at all until I have the proper tools to prepare it right. First I'll attach the complete collection of finds, then add a few closeups of the wood in the thread below.
