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.

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 puzzlin

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 soaki

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 weat

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

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:

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% paralo

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.- 2 replies

Hi there! I am brand new to the forum, but have been a fossil lover all my life. I am hoping to learn the best way to preserve sandstone leaf fossils. I've been finding them since I was a kid and my mother use to coat they in polyurethane, I believe. I'm just not convinced this is the best practice. I imagine the chemicals would deteriorate the stone overtime? Anyways, I would appreciate any and all advice. Thanks in advance! Dea

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 the

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 sands

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.

Last week I visited a silurian site and found this stone. I wonder which kind of animals this is? And which kind of stone, which is blue inside with a relative thin layer of white material on the surface. The animals are "printed" on the surface. Martin

Ratfish tooth from the mid-jurassic in Denmark
Sauroniops posted a topic in Partners in Paleontology - Member Contributions to Science
Hello there fossil forum! A few of you may have read my post about my 2 trips to Bornholm, a Danish island that holds a lot of different fossiliferous geological layers. I had specifically been digging by a location called "Hasle beach", where mid-jurassic sandstone layers are present. There have been found a few plesiosaur bones/teeth there, as well as 2 possible dinosaur bones, still being described, and also a few footprints. Other than that, mostly what you will find here, is shells, and occasionally hybodont shark teeth. As I mentioned in my last post about Bornholm (you- 19 replies

The fossil forum members identified this fish years ago but I lost that information due to a computer crash. I can remember they thought it came from Brazil? and had an age attached to it. I found it at an estate sale in Racine WI. in the basement of the house. The owner said it had been in that corner when he purchased the house and was more than happy for me to take it out of his way. I think it is very interesting but would like more information. Thank you

Found this rock in Wisconsin US near Lake Michigan. Looked interesting but I have no good idea of what they are. The largest length of the black things is 12.7 mm or1/2 in. all encased in the light shaded rock band.
