Hello everyone I wanted to know what exactly I have inhereted from my great-grandfather, he mainly collected minerals and other geological stuff and I never really managed to talk with him about the stuff sadly. While I don't know the exact location of where it was found I am able to pinpoint the region to the southern region of Palatinate in Germany due to the Red Sandstone found in the region and (what seems to be) a small Melanite on the stone with it, which is common in the neighbouring state where I also have relatives which he often visited during his lifetime. All help is appreciated if you have any idea what species it is. Thank you

Went down to the creek this morning to release some fingerling blue gill I raised and stumbled across this. Picked it up because I liked the unusual shape but then noticed one of the grooves looked altered, like it was rubbed or ground. Last year I found a Trinity sinker and Castorville arrowhead in same spot, so started researching artifacts and saw arrow shaft straighteners which this resembles. It doesn't look straight at first glance but a pencil fits in there perfectly. Coincidental and geological? Also found this neat peice of rock and wondering if it's flint? This area of creek is QAL.

Greetings all! Recently pulled this from south shore Lake Michigan near the Mack Straights. Curious as to what the fossilized material is inside the upper shell half which is approximately 2.5cm across. Any ideas? Bonus points if you can identify the shell too Thank you!

I found a few plates of sandstone that I really liked a few years back in Lockport, NY. I believe they are from the Silurian Grimsby formation. I don't remember nearly anything about trace fossils. My first guess from just googling before making this post was arthrophycus. Can anyone tell me what kind of trace fossil is present in these pieces? 1. 2. 3. 4.

Has anyone seen this before and if so how was it formed? Appears to be sandstone, full of striped layers of metal, in ribbons and bubbles - some bubble features are as large as 9 feet. Never seen anything like it. It was found in the honey creek area of big south fork in Tennessee, outside the town of Onidea. See photos.

After publishing some posts on this website it is time to introduce myself. My profession is teacher from west of Norway. As a child I lived in the western mountain each summer in a farm and liked to look at stones in a river nearby. I was very fascinated by the different shapes and colors of the stones. Unfortunately the area do not have any fossils, because the many glacier movements in the area crushed or removed any fossils in the past. But the area is very interesting when it comes to geology as the ladshape is formed by the collision betweeen Laurentia and Baltica in the silurian period and by the great Jostedal-glacier with beautiful hanging valleys and long fiords. The area has many sites with silurian rock which is clay slate or shales changed into phylite, used as a material for house building from ancient time. My interest in paleontology started just 2 years ago, when I began to see viseos and read articles about the subject. I have a master degree in philosophy and wrote a thesis about Aristotle's philosophy. Last spring when me and my friend drove by my car in the countryside north of Oslo, I was thinking of what I read in an article where a fossil hunter wrote that, "when i see a road-cut, I feel at once both sad and happy, sad because they destroyed a part of nature, but happy because i can see into the past". And there I did see a road-cut which seeemed to be a place with fossils. The rock was shales, clay-stones which was very easy to divide with the bare hands. After looking for just 3-4 minutes I found my first fossil, a big part of a trilobite. It was a beginners luck. Later I know the location is from early silur. After that I decided to become a fossil hunter. It was a perfect time to become a hunter in the beginning of corona time. I mostly seach in the Oslo field, where is camrian, ordovician and siluran formations. But this summer I went to the Bremanger area in west coast of Norway where there is 3 devonian formations pushed into land from the ocean. The formation I visited has sandstones in a high altitude, often above 1000 meters on top of mountains. There I only found one stone with some shells, but i hope to visiti the place again with ore knowledge of where to find fossils. I hope to learn more from other members of this forum of my own and others finds and also contribute what I can with my limitied knowledge. Here is a picture of my first fossil, the smaller part seems to be an extension of the bigger and the second largest from the opposite side. The length of the bigger part is 5 cm. I do nt know which species it is. Maybe some other member recognize that? Martin

Hi all. Yesterday, I went on my first fossil hunt in about fourteen years. Went back to one of my old haunts, Jan Juc beach on the south coast of Victoria, Australia (Oligocene deposit - mostly mud and sandstone). I was expecting to find the usual - sea urchins, small crabs, coral, sponges etc. Instead I found a big, dark thing. A thing is all I can describe it as - buried in sandstone with the eroded top showing, I initially thought it could be a toe, or maybe some petrified wood. Once I moved the boulder to my garden and attacked it with a small hammer, what popped out was a little puzzling. It's about as long as a Sharpie (sorry, no ruler on hand, so this was the most universal thing I could think of), and has the girth of a banana. It's much, much harder than the sandstone it was in, and much, much darker. Almost black. The part that was not eroded is in a pretty uniform semicircular shape, which made me think it could be a bone. The breaks you see were present in the thing before I popped it out of the rock. I'm assuming it was originally longer than what I have, as it was eroded away at the edge of the boulder, leaving the small chip at the end. The other end was sheared off at the other edge of the boulder. The rock broke off cleanly around the thing, so it's not a part of the sandstone substrate. Can anyone ID this for me? I know it's pretty beaten up - heavily eroded on the exposed side, and little creatures have started growing on it. Even just confirmation of its status as a fossil or mineral would be helpful. Also, some fossilised coral and shells I found at the same cliff on the same day. Weird little shells with a division up the middle. IDs on these would be greatly appreciated too. Thanks guys.

Normally this sandstone is filled with bivalves and snails of various species in the loosely consolidated. The "rust" color almost always is a biological marker in this sandstone. All of the bivalves and gastropods have that coloration. This specimen was found when a smallish piece of sandstone was separated in half. This half has the "head" I think, the other part has most of the cast of the body (this whatever it is, is bilaterally symmetrical). The only paper I have does not mention annelids. Anyone want to take a guess what this is, sending it to a "real" paleontologist to get an opinion.

Hi everyone, Sorry if this is a bit of a basic question, but I'm fairly new at this and seem to be finding conflicting information about what I'm looking for. I recently found a number of fossil urchins, and what I think look like will probably turn out to be shells enclosed in sandstone on a beach. Some are pretty clean and only have a small amount of sandstone adhering to them, but others are almost completely buried in the piece of rock with only little bits of the fossil exposed. I was wondering what the best way to remove the rock is without damaging the fossil? I've tried soaking them in just water and cleaning with a tooth brush, but it's still too hard to remove most of it. Some people suggest soaking in vinegar, but other reports seem to say that will damage urchin fossils and most of the information I've come up with relates to removing fossils from limestone rather than sandstone. Thank you in advance for any suggestions

A friend likes to pick up rocks and other assorted things at estate sales. Then he brings them to me for ID. But this one is not in my areas of expertise. It seems like I've seen these for sale at rock shops, not sure. And, I'm not certain it isn't some kind of nodule or pseudo-fossil. The matrix is sandstone, with rusty iron color when scratched with fingernail. Also, because it was purchased, its natural location is unknown. il.

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.

Greetings- I found this rock with kids in Montgomery County, Pa., USA, along creekbed. I believe it's a type of sandstone- the Brunswick and Lockatong formations run through county (apologies-I'm just learning geology, it's red-brown). Curious if this is an animal impression? Footprints are known to be found in the area. Photographed at different angle lights, as it looks so different depending. My son showed at school as a fossil- wanted to give him an informed answer. Thanks so much!

I think I've found my "home" here. I have well over 50 pieces (a couple are large - 10-25 pounds) of formation that I've collected over the last three months to "investigate". Mostly sandstone and what I think is deep water mudstone (thought it was shale at first but no layering). Will try the Hydrogen Peroxide to dissolve the sandstones but am at a loss for the mudstones. the mudstones are extremely hard but contain lots of micro deep water (>200 meters) fossils. Any advice? I've included an image in the what I think is a softer mudstone higher up in the Keasy. This is juvenile Dentalium agassizi (20mm in Length) I believe but after a 30 year break I've just gotten back into the game and may be erroneous in my ID. Interesting point is that specimens of Dentalium agassizi were used as the "wampum" of the North American Pacific Coast tribes (have a long PDF on it if any one is interested (Phd thesis I found).

I’m a landscape gardener & came across this fossil in a piece of new quarried sandstone walling. I’m assuming it is some form of Calamite but what’s puzzling me is the solid form that weaved through the middle of it. The specimen is approximately 100mm long & 40mm across the stem. All opinions welcome, I’m keen on geology & fossil hunting in general but I’m no expert! Thanks, Andy

Teeth? Or am toothbrushing rocks? Sand continues to shed and seem to be shaping. Hunt County. Bazaar Sedimentary rock. Only one I've seen like it. Looks like sea coral . Hunt County. I would have completely discounted this because of how white it is except for how it was found and how it looks.

Hi all, Upon examining some of my finds from this hunt about a month ago, I realized that there was an anomaly on one of the Neuropteris ovata pinnules. Initially I brushed it off as nothing more than an anomaly, but last night while I was doing some reading I came upon an intriguing paper on insect galls from the Carboniferous. Some of the gall fossils included bore a striking resemblance to the gall on my frond, and so I figured I would make a post to see if any of you had an idea on what it could be. Here is the frond, in full view: Closer inspection of one of the pinnules reveals a small, oval-shaped bump: This bears a striking resemblance to some of the galls included in this paper (it is not paywalled). Specifically, it resembles #7 in the first figure. I hesitated to include the image directly in this topic so as to not violate any Forum rules (if it is not a violation I can include it here as a reply). https://www.researchgate.net/publication/250613622_The_Seeds_on_Padgettia_readi_are_Insect_Galls_Reassignment_of_the_Plant_to_Odontopteris_the_Gall_to_Ovofoligallites_N_Gen_and_the_Evolutionary_Implications_Thereof Although it superficially resembles a gall, I am looking for other opinions as I have no experience in this field. Here are my thoughts on why it could, or could not be a gall: It could possibly be a gall for multiple reasons. First off, the morphological similarity is quite striking. Secondly, the paper states that ", occurs commonly on a variety of seed-fern foliage throughout the late Middle Pennsylvanian to Early Permian". This is from a late Pennsylvanian deposit (Connellsville Sandstone of the Conemaugh group) so it fits quite nicely into that time frame. Also, epibionts are quite common in this deposit, specifically Microconchus. They are preserved in a relatively similar fashion (mold-cast). There are a few reasons why it could also not be a gall. First of all, I have never heard of galls coming from deposits in the Appalachian basin, though this may simply be due to my own ignorance and/or a lack of literature. Also, this anomaly is isolated, which is a derivation seen from many of the galls included in the above paper. Finally, random nodules and concretions do occur sporadically throughout this deposit, so it could always be mineral growth. And finally, my simple lack of knowledge prevents me from making a confident ID either way. So, what do you all think? I'd love to hear some of your opinions as to what it could be! And on the off chance that it is a gall, should this specimen be donated?

Hello everyone! Just got home from my weekly vacation and started immediately the preparation. The matrix is soft, mostly loose sandstone and once wet you can process it easier. Right now I have no power tools, only some screw drives and picks. The process seems that will take a lot of time. Any advice is welcome. I also need advice concerning some issues. 1. One urchin that after making it wet, a crack was revealed. There is possibility that the crack expanded by half millimeter. How I treat that? Naturally dry it and application of 20% paraloid? Then proceed as above? 2. Another sample has a small piece broken, which of course I collected. The broken piece has some matrix on it and is less than 2cm. Again paraloid and then same process? 3. The drying process can be accelerated with sunlight or this might be dangerous and may cause cracks? Thanks everyone. The first pic is the one I am working now. It was like a sandball before removing most of the matrix and now I am doing detailing. The second is the slightly cracked at 11 o'clock. The white side was exposed in the weather, the rest was within sandstone wall in the quarry.

Still learning my formations. Found these close to the bottom of the Dakota Sandstone formation in Kansas.

Found in clay soil, Cerritos, California.

I dug this up in Wyoming and was told it's a Mioplosus. The soft sandstone came off with only a bit of effort. Now I'm on to a harder crystalized matrix around the most delicate areas. I don't want to lose any of the carbon so I'm asking for help. I've used dental tools and pen razors so far. I see amazing, beautifully completed fossils on this site with no sandstone on them at all. Is there a method or tool I am unaware of?

What doesn't bite, leaves lots of roots and little bark?
Steve Stonelover posted a topic in General Fossil Discussion
Many roots of the Lepidodendron have been found here cast in fine grained, very hard sandstone. One specimen of bark has been found that is in a repetitive diamond pattern reminiscent of scales on a tropical palm type tree. Another one off specimen is of the interior trunk or wood of the tree--(presumably). All of these specimens are the same type of sandstone. This is definitely Lepidodendron country as no other fossils have been found here to date. Pics of individual specimens will be gladly posted upon request.

Hi guys, I recently purchased some processed Harding sandstone, I was looking for unprocessed stuff but I could not find any for sale so I had to just go with this. The fossils arrived today and I have been examining them with my microscope, I find this stuff very fascinating. My question is regarding these fossils here: the ID guide that came with them claims they are sharks but I find this strange, I believe chondrichthyes only appeared in the Late Silurian so how could this be? Are they something else, and if so do we know what that something would be? Also if they are sharks would we not also expect to find their teeth, yet they seem absent in this matrix. Thank you, Misha

I've been adventuring my family property in north-western Pottawatomie county, Oklahoma, for 15 years or so and I've always thought all this sandstone was kinda boring - there didn't seem to be any obvious strata, or differences in composition and no fossils. On Christmas day, however, I went out on the family property to do a bit of photogrammetry of the sandstone outcrops on the property and I stumbled upon a very interesting pattern in the sandstone: I have been told that it looks like bioturbated sandstone, and it certainly looks like some kind of biological pattern. This sandstone belongs to the garber formation in central Oklahoma, and is Permian in age. This is the only place I've seen such a pattern anywhere around here. Is anyone familiar with the garber sandstone or perhaps with similar formations/trace fossils?

I keep finding small rocks at the base of banks alongside the road, around the area where I live in Bath, UK. Most of them contain bivalves but I keep coming across this shape which I can’t recognise (picture 1) Picture 2 is a close-up of rock A which seems least weathered. I think these are the imprints left behind by something but I also have an example of what I think could be the actual object itself (please excuse my lack of terminology!) but it’s tiny compared to the other three examples (picture 3) Any help with this would be great thanks.
