Hi all! Brand new member here but long time geological fan and rockhounder. I am new to Texas and my job site has quite a bit of echinoid and bivalve fossils, and I was out rummaging around in the woods looking for some fossils when a “stone” on the soil surface stood out like a sore thumb to all the geological type base material in the area. In one little pocket in the under brush of cedar I noticed crystalline formations on material that was unique to the whole area. I am new to the whole geological formations but I was assuming it was in the glen rose formation type area. Anyone based on look have any idea? It does not immediately resemble cycads fossils I have seen which thought was the only common large petrified material in that formation. The material is solid crystalline almost agatized with the largest piece weighing 40lbs At first I thought I had hit a jackpot of sagenite. In an hour brought out 100lbs of the material. This stuff is completely set apart from base formations and material fossilized snail, bivalves are found in only with this being 100-200ft away down a small hill. Sorry I don’t have anything to Mark scale I can take pictures with coins or ruler tomorrow for y’all. This is the most pictures I can add for now let me know if you would like more or better photos

Any ideas as to what this might be? Thinking could be wood remnants, maybe petrified or partially so? Northwest PA, lots of glacial debris in area.

I am debating whether to cut or grind smooth in several areas two pieces of Indonesian petrified wood with botryoidal chalcedony that I recently received. This is what I was supposed to have received: This is what I received (The seller removed most of the yellow surface agate.): I just don’t like the look of the pieces gouged and scratched so I want to remove as much of the damaged areas as possible and maybe grind smooth other areas. First Question: Should I try to cut the pieces or just leave them as is? Second Question: Should I cut the pieces along the red lines or somewhere else? Third Question: On the one piece should I also try to remove the top piece to expose more of the botryoidal chalcedony? The back face of that top piece is really damaged. On one side the top piece would be easy to cut because of the void underneath. The other side would be very difficult because the void doesn’t really go all the way to the red line. Fourth question: Are there areas I should try to grind smooth like area1 or area 3 or area 5? Last Question: Should I give up on trying to salvage the pieces and just try to cut out intact the botryoidal chalcedony in each piece? Marco Sr.

Good Morning, I came across this interesting piece about 3' below-grade in Live Oak County, Texas. I've managed to dissolve some of the 'caliche' with 5% vinegar to clean this up a bit. There is pet wood and the occasional Columbian Mammoth molar in the same vicinity as this piece was found. It is relatively light for it's size, compared to pet wood. Looking for anyone who can offer an opinion/advice on this piece.

There are no pictures of this roll shaped rock before the rock crusher. It was approximately 5 inches long and 2.75 inches diameter cut off square on both ends. it had a noticeable double 1/2 spiral ripple in its length. We don't know where it came from. It was found in 1976 in a newly purchased farm house in Michigan.

Hello. I have opalized wood for trading. Age - Paleogene. There are Teredo mollusc passages ranging in size from 6 to 10 mm, filled with cemented opal sand, less often with chalcedony. Insect coprolites are also found. There is a sample of a solid section with annual rings (ground, but not polished). If you are interested in such samples, please do not hesitate and contact us in a personal. Have a nice day.

My 9 year old son found this earlier today. Need help identifying.
NightHawk_AL posted a topic in Fossil ID
Hello, My son and I were walking on a local trail and he found this. We are trying determine if is a bone, petrified wood or something else. We are complete novices, so please forgive us if it's nothing. Thanks in advance for your help.

I dug up a log in my backyard, I would love to know if it is petrified wood.

Hi all! I made one of the the personal coolest discoveries of mine yet - while hunting for petrified wood in tiny, tiny stream on the catahoula formation I found a chip of petrified (palm, most likely) that is completely composed of a translucent mineral, perhaps quartz? I'm curious as to what mineral this piece may have fossilized in. Furthermore, is this a particularly special find? I'm a newbie, so just because it's a first for me doesn't mean it's uncommon. Here are some photos, for reference: and the other side: here it is wet, and held up to the sun. The second photo has my finger behind it so the translucence could be understood Thanks for any help!

Ok, this is my first post, and I think I read the rules right, so if I didn't do anything right just let me know and I'll fix it. So I bought this boulder off a guy. It's about 3 ft long, 2 ft wide, and weighs about 200 lb. The guy told me that it probably came from Kansas or Minnesota. He couldn't remember very well. But I am in Lincoln Nebraska so I suspect it's probably Kansas. I asked a guy for information about it here in Lincoln. Specifically I asked him if this was a petrified log and if the big lump on the side was a concretion. He said that "This is a weathered piece of limestone. Selective sections have weathered and are black/ hollow. I don't see a concretion. On the rock. Concretions can be found in limestone but they are generally smooth and have structure. Petrified wood does not form in limestone and what appears like wood is bedding and parting." He could be right I'm just looking for more opinions. I just feel like this is sandstone and not limestone, but I could be wrong. So I'd just like to know If it is a petrified log, and if it isn't what exactly it is, and any other information you can give me about this. Like what the different formations on it could be, and why the colors are the way they are. Sorry about the night pictures, I just got it back from the car wash where I gave it a good cleaning. I do have day pictures but they're not as good, and I'm just really excited about this. but if better pictures are needed I'll go outside right now and take them or wait until it's daylight. I also had to resize these pics and I'm not sure how they'll turn out. Thanks for help.

Good Evening All, I'm new to this forum and this is my first post. I was hoping someone could assist me in identifying the type of petrified wood I found in South Texas and the easiest way to remove the white minerals around it (providing I even should be removing the minerals around it). There were several pieces found about 4' below-ground on the edge of a crevasse where water was carving out the soil. I am tempted to return with an excavator to locate more of it but will hold off in the meantime. An early thanks to anyone who can reply and give me some guidance.

I would rather identify most any fossil other than petrified wood! Not a botanist, so when I referred to my ancient copies of Gems & Mineral magazines from March to August of 1960 and read Virginia Page's "How to Identify Fossil Wood", I got lost in a hurry. I'm trying to identify wood from the Cretaceous in Southeast Missouri at Crowley's Ridge. I have a polished cross-section image and am hoping someone can identify it for my fossil database. I don't have a longitudinal section, but could do one if that is necessary.

2 Venice beach fossils. Petrified wood and odd worn shark tooth? Very curious.
FemurIHKH posted a topic in Fossil ID
After a trip to Venice Beach, Florida, I'm having trouble with identifying 2 fossils found onshore. The first is something I initially thought was a well worn micro shark tooth, but on closer inspection am having doubts. There is also a piece of what looks like petrified wood. Perhaps pine? Any help or resources would be appreciated. Thanks!

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.

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

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?

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
