I'm interested in petrified wood for both the scientific value (wood where the cell structure is well preserved) and for the aesthetic value (mineralized with vivid colors and crystal shapes). Below are two petrified wood slabs from my collection. Black (carbon) and White (silica) Slab: Below are some close-up pictures taken with my digital microscope that show the wood structure in this black and white petrified slab: continued in next reply Marco Sr.

Drove south of San Antonio to Tilden, Texas to check out our favorite petrified wood location. My wife and I found some decent pieces. Some are very “tumbled” from the creek but other pieces have retained their wood characteristics. Bonus is that I found a scraper type tool that is probably as perfect as a piece I have ever found. Last trip of 2020.

Hello everyone, Merry Christmas! I have a few hunks of petrified wood I want confirmed, all three were found in the Denver area. I'm expecting that they're just all different examples of agatized petrified wood, but I want to make sure. The first two have been in my backyard since we moved here, the third my uncle found in his yard and gave to us. My question is, if they're all agatized petrified wood, how come they all look so different? Thanks in advance for any help you can provide!

I found this rock the other day and kept it because it was strange. There are some weird layers black and brown. The black looks metallic but it’s not magnetic and I thought hematite maybe, there are also a lot of small lines perpendicular to the layers, any clue how it formed and what it is? There is also a small sliver that looks like a piece of petrified wood I have. Oh and it’s about 3 cm long

Strange Holes on Petrified Wood Bark from the Mid-Late Eocene of Texas
Ramon posted a topic in Fossil ID
Hello, I found this piece of petrified wood last month. It comes from Middle Eocene (37-35 million years old) terrestrial sediments, from the Yegua Formation of eastern Texas. What I love about this piece, is that it is a piece from the bark of the tree. The tree that this specimen belonged to, was some kind of hardwood species (angiosperm), probably something like maple or birch, judging by the structure of the wood in one of the endcuts/endgrains. What is so special about this piece, is that the bark side is covered in some sort of carbon film material, which gives it a nice, dark brown-black coloration. What is also very intriguing about this specimen, is that it has a couple of oval, conical shaped holes. They have a diameter of 5-6 millimeters, and a depth of 3-5 millimeters. At first, I thought these were the egg niches of cerambycid beetles. But they don’t quite match the shape of beetle egg niches, or other insects burrows that I’ve seen online. The egg niches of beetles have a slit at the bottom of the dent. They are also shallower than the dents in my piece of petrified wood, and are almost never arranged in a way, that is parallel to the wood. Now, I’m starting to think that they might be feeding holes, done by a woodpecker while foraging for food. From the information I’ve seen online, and the pictures that I’ve seen, they very closely resemble the holes in my piece of wood. Foraging holes done by woodpeckers are elongated, and cone-shaped (meaning that they narrow out into a point at the bottom of the hole. They are often aligned parallel to the direction of the trunk, and have a more neatly arranged orientation, than insect burrows/borings. The holes in my specimen meet all of those characteristics. They size is also what you would expect from woodpecker foraging holes. Here is the specimen Here I’ve highlighted the holes in the specimen Here are some close-ups of some of the holes. (Notice how they narrow down to the bottom, which is a characteristic of woodpecker foraging holes.) I wanted to know what you guys think of this.

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!

This is about 38cm (14") in length. About 22 cm (9") circumference. Cross section is oval shaped about 5cm x 8cm (2" x 3") It weighs about 3.2 Kg (7 lb.) It feels very dense. The surface has pock-marks that look like they could be where leaf stems had attached at one point. The cross section doesn't have any features that I think look like vasculature. The paint on it happened because it sat on my father's fireplace for years and years, and it must've been dripped on during a repainting of the living room. My father and I found this on a Boy Scout hike sometime around 1989 in eastern Tennessee. We thought it was interesting so we packed it out. I was a kid at the time, so I don't remember any other details. We always just assumed it was petrified wood, and I haven't thought about it for years. However, he recently passed away and I dragged it home to California. Everything about the item looks like a prehistoric plant to me, except the cross section. I don't see any detail of how the plant would've transported water. That part makes me skeptical. But the surface sure looks organic. Any help confirming or denying that this is an actual fossil would be helpful. I hope I included enough detail for my first post. Thanks,

The stuff from the Bearpaw formation no one talks about
LabRatKing posted a topic in Member Collections
These came to my personal collection from an auction at a high school that shut down. Normally I prefer to dig my own, but these were too cool to ignore at a buck each. I got lots of other science stuff too! Nothing like picking up a few goodies on the side while buying glassware and microscopy stuff for work!

Hello everyone. I'm in the ATX and often in Smithville TX looking for petrified wood, fossils, and arrowheads on a family ranch. Here to learn more about my findings and look for new areas to explore.

Pretty sure this is petrified wood can you confirm this. And then the little hole on the one side is deeper than it looks in the picture (about as deep as it is wide) is there anyway to say if this was caused by erosion or from something living before fossilization

The snow and ice has arrived where I live in Alaska so need something to look forward to for next year. Will share a trip I had in April when the pandemic closed my office so did what was recommended with social distancing about as far as you can go in Alaska. I made arrangements for fuel and loaded up my home built aircraft called a Glastar with a friend and his son to accompany in another aircraft and headed down the Alaska Peninsula on an adventure. About half way down we came across a dead walrus and were able to salvage the tusks which is legal and will make nice cribbage boards some day. Even though the Japanese are not still making and using glass float winter storms kick up old ones that have been buried and we picked up a few for the garden. Camp set up in the brush to help protect from the horrendous winds that can occur along the Alaska Peninsula. I bring a nice camp with a screen tent for cooking and to protect from the bugs which on this trip had not come out yet due to it still being cold at night. Frost in the morning. We had a day of fishing for trout with the nice weather to enjoy without the normal winds. The fly is one of my own creations. Back at camp with real food , moose tacos. With the weather still holding the following day decided to fly all the way to the end of the Alaska Peninsula beach combing and see what we could find from the air hoping for another walrus. It was not to be but we did check out Unga Island which is on the Pacific side by Sand Point where there is 5 miles of beach with petrified wood. This exposure is where the fossil wood is. Active volcanoes in the background. On the return trip back up the peninsula stopped at Aniachak Bay to look at the dinosaur tracks exposed at low tide. After a mile and half walk started to find the trackways and a couple of big tracks in blocks. Hope this picture assay give you something to look forward for when the snow melts. Cheers; Bob

From an old collection of US domestic petrified wood pieces from various locales, this piece did not carry any identification, and internet searches have been surprisingly shy of items that resemble it. The color in the pictures is true, and there is no fluorescence in lw or sw UV light. Has anyone seen anything resembling it?

Here are a few pictures from another recent trip to NSR. Nothing special again but also a few interesting items I have no idea that they are. Anyone know what some of these pictures are of?

I feel like these may be something plant related because of the structure, small dots on the one piece, and the leaf print I see on a couple of the pieces. I found several pieces similar to these in the same area . Some are really dark and heavy/dense. Some look squared off or broken off at the bottom. They just look uncommon or unlike the other rocks found around that area. Found in a river in mid Ohio area. Any ideas ? Thanks for all your help!

Found this at the edge of a shallow stream bed that flies down from Smoky Mountain region in East Tennessee at Indian Boundary Lake near Tellico Plains Tennessee at edge if Cherokee National Forest. It measures 2" long, 1.75" at widest 1/2" deep at deepest. A bit more flat on one side. Cross section shows a thin outer layer. Outside look reminds me of wood but I don't know. Looks like photos too big so I will load another below.

Petrified wood trip in the Triassic of Pennsylvania
traveltip1 posted a topic in Fossil Hunting Trips
I enjoyed a productive weekend hunting petrified wood in the Triassic age, approximately 210 mya, Newark Supergroup of Pennsylvania. The first 2 photos show a single specimen's 2 sides, illustrating profuse checking in the wood, and a likely rotten dead limb knot at top. Specimen weighs 19 pounds.

Just found this on a morning stroll on a beach near Whitby, North Yorkshire, UK. Thought at best it may be a piece of reptile bone, maybe a piece of wood if not. Saw some nice plant material too, we were going to pick the larger pieces up on our return trip but the incoming tide made us decide against it. Thanks for looking

I found all these pieces in arapahoe county Colorado. I’m not sure where I found #2 just in Colorado. I polished a couple of them, 10-16. Is it possible to determine type of wood or approximate age?

Hello! I found this a while back around Melbourne, FL on the beach. I've gotten two guesses on what it is, whale bone fossil and petrified wood. I originally thought petrified wood too but there's a spot on the inside where there's not so much of the gray... sediment? and I feel like it might be bone structure, the brown lines? I'll show what I mean at the end. And thanks in advance! This was my first actual beach find and I know almost nothing so I'd love to hear anything you guys can tell from it! (The brown lines around the top) And an example I found online below, the one on the right has lines like it.

Need some ID help please. Found on the beach in South Carolina. Roughly 2” by 1.5”. Thanks.

I am taking a family vacation out to Sedona and saw that the Arizona Petrified Forest is close by so I'm planning a half day out that direction. Does anyone recommend a good place to look for that nice red petrified wood that you can keep? I know the park is off limits to collecting but assume there are places close by that you can collect.

Last night I scored! A house threw out a ton of stuff, told my friend stop the truck and have a look see. A big recycle tub had over 50 pounds of rocks and fossils. I have a large hunk of quartz crystals, several with decent clusters of purple crystals (amythist?) A good 2 or 3 pound hunk of petrified wood in great condition, rock solid. A small stalactite and a huge (20 pound?) stalagmite. One is pointed and comes from the ceiling, stalactites are rounded and form on the floor. Also a geode the size of a grapefruit. Geodes are spherical rocks that contain hollow cavities lined with crystals. The name geode comes from the Greek word Geoides, which means "earthlike. I was going to attempt a nice clean cut with my angle grinder and cut off wheel but you really need a diamond blade. So I dropped it on the concrete until it broke into several chunks. It had a good void inside, all bearing small crystals, nothing spectacular though. The Giant quartz crystal, star of the show ^ 2 views of the petrified wood, not a great pic of the end but you can see the rings Small one is the stalactite, larger one is the stalagmite. Part of the geode. the purple ctystals.

Hello and good evening! I have passed this fossil a few times and it resides in a large limestone slab. I believe it could be a spine due to presence of Chondrichthyan teeth in the area and how it appears to come to a point. For reference the teeth I have found include teeth from Petalodontiformes, Eugenodontida, and other Chondrichthyans. I will note I have found some petrified wood in the area, but none in a limestone matrix so it could be a Calamite. Location: Missouri Time period: Pennsylvanian Formation: Muncie creek shale member

Hello Fossil Forum! I love rocks and rock hounding (but very amateur) and I look at the ground wherever I go. I picked up these rocks from a few locations in Montgomery County, Pennsylvania. Most collected over the past year, found in hillsides (not streams). I think that they all look somewhat like petrified wood and was curious if anyone else has found similar samples from this area and/or knows anything at all about them. Thank you in advance for any thoughts, information, and opinions!
