I found this piece of late Cretaceous petrified wood in the Dawson formation of Colorado. Most of the piece however is this grey ash colored rock and I was just wondering, 1. What type of rock is it? I’m willing to do tests such as scratch and hardness if it will help. 2. How was it formed? 3. When was it formed? Did it form during fossilization or much more recently? Thanks for any and all help.

Hello, As I'm not super familiar with petrified wood structures, I'm questioning if this is indeed a vertebrae creature that petrified along with the wood or just a a normal structure. It's little if so. Found either along the Mississippi River just north of St. Louis, MO or in a ravine surrounded by steep hills in the St. Louis County Suburb region. From what I read, Missouri Petrified Wood is from the Cretaceous Period. Any help if it is something and also maybe type of wood/tree?

Carboniferous wood with crystals for trade
Svetlana posted a topic in Member-to-Member Fossil Trades
Hello. I offer for trade fragments of petrified wood of the Carboniferous period with crystals of smoky quartz. Some samples are in the photographs (I did not upload all the samples I have, since there are quite a few of them - of different sizes and qualities, as well as the sizes of the crystals themselves. I think we can agree on what specifically interests you - I have no doubt that I will find the sample you need). The origin of this wood is Ukraine, its age is Carbon. I'm interested in marine reptiles and petrified wood. Thank you. Have a nice day-

I recently purchased a "Pay Dirt" box from forum member MikeG @Bone Daddy's site for a little something to do. In it was this piece of wood. Originally it was a very dark brown, almost black color (imagine that from Peace River). Anyway, I went over the front of it lightly with a 600 grit sanding cloth & the color lightened up nicely. Filed & polished a bit of the upper end & found that it may not be regular wood. Measures 7 cm long by 2.5 cm at it's widest. First 2 pics are the front & back. Pics 3, 4 & 5 are the polished bit at 60x, 75x & 100x respectively. Not used to seeing round in pet wood, so I thought I'd see if this is possibly palmoxylon instead.

My Petrified Wood from the Dawson Formation of Colorado
Top Trilo posted a topic in Member Collections
In Colorado there is a formation called the Dawson Formation also known as the Dawson Arkose Formation. The most common fossil by far is petrified wood and although I haven’t found any vertebrate fossils from dinosaurs and mammals have been found. It covers a relatively large time span from late Cretaceous to early Eocene, about 70-54 million years old. A member that has also found fossils in this formation, Blake @FossilDudeCO. Although it has been over three years since he was on his posts have still helped. He said that further south is Eocene but higher north in Parker and Aurora is Cretaceous and from the cinnamon tree family. That’s all the basic info, now it’s time for the pictures. The next four are wet to show the color a bit better. The next three are polished via rock tumbler. The next image sparkles like sunlight on snow but you can’t really tell with a picture. While most are brown and black there are hints of color everywhere. Red, and clearly wet. Orange Yellow is mixed in a lot of them with a lot of it being a yellow brown or yellow white color. This is the only rock I have found with green in it. Very strange if anyone knows what any of these minerals are I would love to know. Blueish Purple grey Ill take pictures of more purple ones shortly. Here are just more pictures, Enjoy The largest piece, the first image, is my favorite and largest find being 8.1 pounds (3.7 kilograms). FossilDudeCO said in a topic, "It is thought that the trees fell into standing water and began to deteriorate that is why we don't see lovely rings or any more definition to the wood, rather just strange mashed up chunks and bright colors!" Which I am perfectly fine with. In case you didn't read between the pictures, if anyone knows what any of these minerals are I would love to know.- 7 replies

i was out hunting white river fossils on a paid ranch near chadron nebraska. found an area with occasional typical mammal and turtle fossils but also large amounts of these layered agatized rocks that I hope are petrified wood. also found were occasional yellow brown translucent "melted wax" pieces that I was told was derived from sap. I thought this is great and brought enough home and now I wonder is it petrified wood or if it purely geological. Please take a look and tell me what you see. there are other areas of badlands within her ranch that have clearly agatized mammal bones, and other areas with purely geological layers of agate and crystal.

I have a decent collection of petrified wood I've found here in Utah mainly Triassic Chinle, Jurassic Morrison, and Cretaceous Cedar Mountain Formations. This one has me a little stumped though and I am mainly looking to see if anyone has seen something similar to this. I'm about 80% sure it's jasperized petrified wood. Possibly an old rotting log. This was found near Park City, Utah in Keetley volcanic strata. The locality is not from the ash deposits that produced the nice Silver Creek Junction petrified wood (now extinct under commercial developments) but more likely from the violent lahar deposits that came later. No scraps of petrified wood were found. Just this. More info here. ANCIENT VOLCANOES OF THE CENTRAL WASATCH RANGE

Hi everyone! Recently I bought this piece of blue petrified wood. In the process of cleaning, I have soak the whole piece in muriatic acid for about a day and half, and in water with baking soda for about 2 days to neutralize the acid. To my surprise the whole skin turn white and the dark blue part has turned much pale in color. I have attached a few photos below for your reference, please noted that when the whole piece is dry the white part is complete white and opaque, but when I added water, the white part became translucent. I am not sure if I have somehow damage it, or if I need to do more to remove this 'white skin'. I would appreciate anyone's advice on what is this white stuff, why adding water would change the opacity and what I should do next. Thank you. These are the photos when I first bought the petrified wood, note only the top part was cut and polished, no treatment done as yet This is after soaking in the muriatic acid for about a day and half, and in water with baking soda for 2 more days, the whole piece turned white, even the polished side change from dark blue to pale white brown color. This is after adding water, you can see the polish part has turn darker brow and the white part became translucent.

Hello. I want to show you some examples from my collection. This is a Carboniferous wood. The preservation is not the best, but for me these samples are interesting for the presence of crystals of smoky and ordinary quartz on them. A sliver that has broken off from a larger fragment. There is more quartz than wood Perhaps a stem or stump - it is almost round in cross section. And thickly overgrown with crystals. Large flattened fragment; perhaps the first sliver was from it.

Found this item in a creek in the blue ridge mountains. It is very heavy for the size. Any thoughts on if it could be petrified wood or just a schist rock?

I'm told this may be petrified wood but it looks a bit different from the petrified wood I've seen from the southwestern states. Found on a beach in northeast US. Please let me know your thoughts. Thank you --Dwight

Good evening. A couple of days ago I managed to go to three places with petrified wood at once. These outlets are not nature reserves; most often, these are fields that are just cultivated, roads and natural outcrops of bedrock (gullies, ravines, etc.). The first place is a small field, as well as a forest protection strip near a spruce planting (it was just plowed up). On a country road, one can see the rock outcrops, in which the wood is hidden. Large cobblestones are also found in the root-bed, but more often these are small slates. Orange clay is a sure sign that the layer we need is emerging here. Nature is waking up. Another forest protection strip... And the first finds. These are fragments of petrified wood from the Carboniferous period; but after meeting with the tractor, these are most often fragments. It has been raining recently, so the wood is easy to find. Nature amazes with its beauty! A few more pieces of wood and it's time to go to second place. Sometimes fragments with smoky quartz crystals come across. Carboniferous outcrops. General view. A sample of wood - most of this place is exactly like that. The second place is another field, and all the roads that lead to it The finds are embedded right into the road. There are also many fragments of wood in the gully - they have even been washed. You don't have to turn off the road... A sample of wood - most of this place is exactly like these. The samples are highly silicified, the structure of the tree is almost not preserved; but light quartz is visible within this specimen. Perhaps grinding and polishing will make the specimens worthy of the collection. Third and last place on that trip. This is no longer a field, although they are here too; these are old quarries. According to rumors, there was once a lot of petrified wood here. On this trip we did not find any fragments - it was starting to rain and we had to leave; besides, from this place we could not take anything - too close to the reserve. Heaps of broken stone are everywhere. The bedrock occurs at an angle to the surface. General view. An old tool. In the pit, where the stone was once mined, now a tree grows. A couple of photos before leaving. We did not find a petrified tree in this place, but we picked up such a fragment in a nearby field. A lot of iron, a lot of quartz. That's all for today. Thanks for attention. Have a good evening.

Hello. From a recent trip to the Perm-Carboniferous petrified wood, we brought back some very interesting fragments; nothing like this has come across before. Usually we find fragments of wood (chips), without knots, without a pronounced structure - just highly silicified, indeterminate fragments. But while this trip from a small area (just a couple of square meters), we collected several interesting fragments. This is a solid piece of the trunk with knots located at the same level. 7 knots. Another similar fragment, but split lengthwise. There are only 3 knots left, but a cavity with smoky quartz crystals has opened. I want to identify these findings. Having looked at the photographs and drawings, which depict Araucaria, I saw that the branches of this tree are arranged in "layers", i.e. on the same level. Why did I take Araucaria as a basis - in some literature, local layers are called Araucarian. I would be glad to receive any information. By the way, I have a similar trunk with knots on the same level - but it is from the Paleogene; much better preserved, replaced by chalcedony, and has 5 knots.

(Almost) microscopic agates in petrified wood
ARandomFossil posted a topic in General Fossil Discussion
I thought I would share this unique piece of petrified wood I own. I don’t know if this is rare, but I couldn’t seem to find anything on this. To the naked eye, the rings of the wood are tiny white rocks. But under the microscope, you can clearly identify agates. Fraxinus Nigra is the name of the species. The microscopic pictures are too large for the post, but I think you can download them to view.- 9 replies

I'm trying to identify the polished fossil material in this Georgian English snuffbox, circa 1760 to 1820. Is it mammoth ivory? Walrus? Wood? Something else? The material is set in unhallmarked sterling silver. Thanks in advance for your suggestions. Adam

I believe this is petrified wood. I Found this and a larger piece, but the larger one is a different texture. It's more smooth with dimples and I was able to figure out identification of that one, but I'm not so sure about this one. Any information?

From the album: PLANT, WOOD & MINERAL SPECIMENS
In the Early Pleistocene, about two million years ago, these twigs and bits of trunk were driftwood in the paleo Santa Fe River. The waterlogged twigs sank to the bottom in a basin in the river channel. They became buried in a highly organic mud during seasonal flooding. This anaerobic, low-energy burial preserved fine details such as bark and even insect borings. The wood is thoroughly mineralized with apatite -- it 'clanks' when two pieces are tapped together. This wood is dated biochronologically by the vertebrate fossils also found in the mud, notably Holmesina floridana, a giant armadillo. Fossils of the beavers Castor and Castoroides, muskrats, grebes, cormorants, ducks, and large fish suggest that this was a backwater pool in the river.© Harry Pristis 2008

Ok found this Odd thing at first thought it might be petrified wood but I tried looking at it through a microscopic camera and could not find any of the basic fossil wood cell structure that I normally find on petrified wood. There are places on it that look mesh like? ....well I took a close up of it ... if it were some type of bone the inside would be darker right?....just not sure with this one. Found in a gravel load from the bed of the Brazos River near the West Houston Texas area.

Howdy, Couple day old member here. I am a Landscape Professional and I see alot of river rock. Lately I've moved to Austin, TX and have noticed alot of petrified wood in the rock materials we use. I'm 99% positive it is all native, locally sourced in the Texas Hill Country. Anyway I have a few pieces I'm curious to whether it's machine marks or not and a couple pieces I'm not sure if they're just gnarly rocks or not. Petrified wood ID is what brought me here and I found some good info so I signed up. Any information and help is greatly appreciated. Thanks yall!
