Petrified wood or Schist rock?

packgirl posted a topic in General Fossil Discussion

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?

Possible Petrified Wood?

DVL posted a topic in Fossil ID

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

Hunting trip for Carboniferous Petrified Wood

Svetlana posted a topic in Fossil Hunting Trips

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.

Carboniferous Petrified wood for ID (Araucaria?..)

Svetlana posted a topic in Fossil ID

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.

What Do Past Tsunami's Leave Behind

Crgold36 posted a topic in Geology

I can't find much history or geological information of the Seattle area in Washington State before the people started settling there. I get lots of history about how everyone settled, who they were, dates of events, and the beginning of industries. Is there a easier way to find out through other resources about actual formations of the land and geological events that have happened in the past throughout the centuries? Is that made available to the public for research in their findings of fossils? There's more then I thought to learn about when it comes to fossils, and when it comes to fossils being found in or out of profound areas where you don't know how it may have got there, takes you more on a history hunt for answers to the how? question, and the when? question. Finding a fossil in someplace that makes you scratch your head???.. I'm sure this has happened many times. Hasnt it?.. Ocean animal fossils no where near the ocean? I believe that would be evidence of a past tsunami. Could there be any reason why sea fossils would be found in the middle of a populated city not really that close to a Ocean but close to a man made lake. Half salt water half fresh water. I think there should be a key importance to explore more of city populated areas before major construction. Seattle is a place that has never been explored geologically so much other then the beach along the coastlines. I find no evidence of geological history of Washington but of our volcanoes, not so much tsunamis at all. Seattle has just been built on top of so quickly, that Seattle hides a whole lot more beneath the high rolling hills and valleys surrounding then we think. There are less and less places to explore in a growing city and I'm not a expert, but when I can notice something out of the ordinary and you know it's of importance, how can it not excite you enough to find out more about it! So who's the first one I would call to report a geological formation of importance? How are those steps determined in the concept of discoveries ownership and so on? The laws are so twisted and much goes into it. The reward it's self in fossil hunting or just stumbling upon one is the past answers they give us, but they are our future answers too!

Fossil ivory or wood silver snuffbox ID

agman posted a topic in Fossil ID

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

Petrified wood identification

Rubykicks posted a topic in Fossil ID

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?

Beetle Borings on Petrified Wood

Harry Pristis posted a gallery image in Member Collections

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.

Just Weird...What is this???

hndmarshall posted a topic in Fossil ID

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.

Landscape River Rock Finds

AggieGrass posted a topic in Fossil ID

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!

Clarno Wood Dig

ErikAndere posted a topic in Fossil Hunting Trips

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 (read: it was windy and I got lazy!) There was a scattering of other wood in the area, of varying levels of preservation; the formation wasn't rich with it by any means. No observed leaf fragments. Most of petrified wood we get out here is carbon-black, poorly preserved or just little brown float fragments, so finding something this bright made for an exciting day.

Brazos River Petrified Wood/Bone Questions

Blxbrry posted a topic in Fossil ID

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

Unknown Fossil Please Help Identify

Chingazzin1 posted a topic in Fossil ID

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

Red Agatized Petrified Wood, Possibly from Madagascar: Could anyone tell me more information about this?

Ash Tree posted a topic in Fossil ID

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 more of the details in the coloration. When I went to research the process of identifying tree species from petrified wood, I came across high powered microscopes that could identify structures on a cellular level. I don't have access to that sort of technology, but I was wondering if anyone has any guesses as to what the species could be, how old it might be, what it might be made of, or any other information that could be gathered from looking at the specimen. I'm always curious about what the prehistoric "story" could be behind a fossil, or anything related to the unique biology of ancient life. Thank you for your time, and your knowledge is greatly appreciated!

How To Create Fossilized Wood?

madeland posted a topic in Questions & Answers

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. It may be strange to ask but oddly topical as well - humans have been doing a lot of musing on the future fossils they are creating now. I have done a lot of research to this end, but have not found anything definitive. Maybe I'm just not looking in the right place. What I have managed to glean indicates that wood placed in sediments rich in silica may fossilize. This is very broad, but it is a start. My first thought was recent volcanic ash deposits like near Mt St Helens, but due to the cataclysm that laid the ash, there is likely to be a lot of wood in those deposits well situated to fossilize. I would prefer a situation where the petrified wood would be unusual and likely to stand out to the future intelligent being encountering the piece. There are many valleys in Nevada with non-draining basins that have seasonal lakes, and many of these are reasonably rich in silica, being derived from surrounding mountain ranges that are composed of silica-rich rock. This might be a good location, although I am still wondering about depth of placement, best soil moisture levels, and whether the alkaline conditions would be a problem. Another idea for a place would be a Volcanic Ash Flow Vernal Pool such as Boggs Lake in California. I am not sure what the pH of this soil is- fresh volcanic ash can be very acidic, but this would leach out over time, possibly creating an alkaline situation as the closed lake basin accumulates salts. Any help would be very much appreciated! I am looking for places in the western US, but really any place given as an example would be helpful. Daniel
