I found this concretion with something inside, looks like half of a nodule with something bone alike. Found it while sifting for Miocene shark teeth in a clay quarry in the Antwerp region in Belgium. I think the gravel i'm sifting is Pleistocene with reworked Miocene as i've found pieces of Mammoth bark in it as well. This piece leaves me clueless tho.. The concretion measures 9cm x 5cm sorry about the poor quality pics, that's the best i can get out of my smartphone... Thx!

The other day I found this strange looking rock on the beach at Port Mulgrave- a well known fossil hunting site near Whitby. I'd be interested to know if anyone has any ideas as to what it might be before I go ahead and hammer it out...it looks like a typical nodule from the area with several distinct lumps. I hypothesise a group of Ammonites but this is only a guess. Any help would be much appreciated!

I recently found a lot of what I believe are belemnites on a beach in Purbeck (top row in photo). Along with them there were a number of knobbly cylinders. Some were straight cylinders with a rough texture (2nd from top, centre), others were formed of lots of almost distinct nodules. Does anyone know what they could be? Thanks! (I'm afraid I don't have a ruler here, but have put a pencil in for rough scale reference)

I am just doing a rare Coccosteus from Egerton fish beds, Tain, Scotland Normally not worth for a story, but this is a fossil I stored now for nearly 40 years... Got it from a friend in parts, never started the prep because I expected it will be bad Last weeks I started to finish it, glued and filled the cracks and started working Only with air pen (HW70 and 10). Wow, the skull and the complete armour are preserved and perhaps the body. Never expected this.... Have not done a pic when I started, but today I thought it iw worthy The site is closed due to vandalism in the 80th, so its nearly impossible to get material from there Fishes are preserved more 3-dimensional, not flat, always in nodules Lenght of the nodule is approx 30 cm I will update when its ready, think in April the second pics shows the situation when I started, only the inner parts could be seen and mainly covered with matrix

While prospecting on my Permian site, I came across a hill covered in rounded nodules. As I looked at them, I found a broken one that looked like a geode and others were weathered out septarian nodules. So I picked up a couple whole nodules to bring home. I'm happy with how they look after cutting! I just need to find a way to keep the outside from fracturing while cutting Even better, they have UV fluorescence!

Hello, I opened/cleaned off some nodules I had collected recently and I am unsure if they are fossils or just formations of how the rock separated. Thank you in advance for your time. Also, if anyone has any recommendations on fossil books, that would be appreciated. 1) I am not sure if my eyes are lying to me or not but I see what could be a shrimp. I see the formation of a shrimp body. Also what appear to be two eyes and a nose. Again, maybe I am just seeing what I want to see. 2) Not really sure what this could be. I did not think it was anything at first but then I opened another nodule (3) and saw the same formation. Possible bivalve? 3) Same as 2

Hello, I am new to the fossil finding hobby. I have been finding nodules with no discernible fossil but are different than others. If anyone could tell me what these are, that would be great. Thanks for your time. These 2 have grey circles in the center. Are these just mineral deposits? This one is similar but it also has crystals in the center, almost like a geode? Then I also find nodules like these that have this strange inner part.

Hello all, With the start of this month I have gotten back to doing some fossil prep. I am still very much learning but I am happy with how this one turned out. It's a Callianopsis clalamenis nodule from the Pysht formation of Washington State which I found this past January that preserves two sets of feeding and defensive claws as well as some disarticulated shell material. This prep was fun and I am excited to try another shrimp, they are a welcome break from working with very hard pyrite nodules from Yorkshire. Before prep: After about half an hour with the scribe, the first two claws are showing: After about an hour and a half: Finished. . . for now, until I smooth the matrix: I hope you enjoyed, Benton

I received these very strange Triassic nodules from Madagascar,an opinion about the ID? Half nodule,i think it's not a fish skin on it,Pehaps a claw?

With the start of 2023 I decided to take a break from my long running prep project and prepare out something smaller to start the year off. I collected several of these C. clallamensis shrimp nodules last January and in my previous experience they tend to prep well. This was one that I had split on the beach so I knew that there was a large-ish claw and hoped nodule contained the rest of the arm also. The nodule before prep Unfortunately this nodule didn't contain an arm but rather a bunch of fragmentary shell remains and one large disarticulated claw, but the claw tip glued back on nicely and I decided to have a play with shaping the matrix resulting in an interesting bowled out effect. In total the prep took about 3.5 hours with my Ken Mannion TT pen and I'm quite pleased with how much I managed to undercut the outside of the nodule without breaking it away. While not the best shrimp this was a fun prep to start off the year. Thanks for having a look

Hello everyone I was browsing on a well known online auction site a few nights ago and spotted this fish fossil. Thinking it looked interesting with a current low bid I put in a cheeky last second bid and got it. It was listed as 'prehistoric fish fossil, Sandstone, two halves' so that's not a lot of help in identification. Looking at the preservation before and after purchase I'm thinking it is from Brazil? Potentially the santana group? Preservation isn't preticualy great, especially around the head and it looks to have partially fell apart because of this I'm not sure of the identification. I'm thinking Rhacolepis? Mind you I could be completly barking up the wrong tree! All comments welcome.

Hi — I was lucky enough to collect a few dozen Mazon nodules this weekend. But I am not familiar with how to best prepare and understand this material. Is there a guide that would answer questions like these: • Do I freeze-thaw specimens where fossils are already showing? What about 3d fossil that is partially obscured by matrix? • Are fossils best viewed wet or dry? (seems like dry) • How do I know what's a blobby worm or jellyfish vs a blobby bit of matrix? • Are there categories of finds (besides obviously empty nodules) that are not worth posting for ID? I'm having trouble answering many of these questions based on googling around the forum, since so many threads highlight specimens that seem quite conspicuous and outstanding compared to what I'm seeing so far. Tagging @Nimravis Would also love to learn of other Mazon enthusiasts who might like to be tagged in future threads.

After the last one (link here: fish skull ) turned out to be a nice skull, I'm wondering if anyone could ID this bit? It's very 3D and hard to photograph without image stacking so I've given three views. Phosphatic nodule, Brigantian (U. Mississippian) marine shale, Co. Durham, UK. counterpart:

Is this just a nodule inside another nodule ?? Looks like is wraps around its self but I can’t see any markings of any kind

Found in lower Jurrasic, Liassic Clays at Seatown near Lyme Regis, Dorset, England. In Lower Liassic Clays, Jurassic rocks, close to Belemnite beds. Curved shape and heavy for size, made me wonder if it could be a rib fragment from Ichthysaur. Could just be limestone / Pyrite nodule, but I don't have enough expertise to know..Thanks. Greg.

Hi and thanks for looking at this. While looking for shark teeth in Northwestern New Mexico, I coaxed out a nodule that had half weathered out of the lower section of a sandstone ridge. It was fairly large (approx. 2ft diameter) and was crumbling apart, so I only grabbed the big piece as I thought the quartz looked pretty cool. It cracked open on the ride home and revealed what I think is a fossilized bone. It is a small bone and I'm not sure it can be identified; maybe a confirmation that it is actually a bone fossil would be great. The pictures are terrible right? This phone....

What’s the difference between a concretion and a nodule
Fossil finder 100 posted a topic in Questions & Answers
I have tried looking up the difference between a concretion and nodule and can’t seem to get a clear answer. I have seen both terms used on the forum but don’t know the difference and would like a clear answer so I can know what I’m talking about. Thanks ahead of time!- 3 replies

Hi All, Here is a Eurypterid in a Pennsylvanian age siderite nodule from Indiana. I'm hoping someone can point me towards a family, maybe even genus, ID for the specimen. I know the images don't show many of the fine features but I'm hoping the overall shape is distinctive. Also, I'm just starting to wade through Eurypterid PDFs now but if anyone can recommend a good review manuscript for the group I'd be grateful. Thanks for your consideration. Here are the two halves of the nodule:

Hello dear forum members, among the collection of my late uncle there was a box of coal fossils, most of which are flat crumbly pieces of plant material. I left most of these in their protective wrappings for now. among the fragments on the bottom of the box I found some nodules, I think these caught my uncles eye and where collected on the same trip as the plant fossils. (from Germany, hard coal, not lignite, thats all I know). The nodules are heavy like ore minerals (pyrite comes to mind) There is one with an interesting texture. Maybe a coprolite?? @GeschWhat? Will post more plant fossils another day, probably after we move in july. Is paraloid adequate for crumbly coal?

Hi! I’ve been working on opening some nodules from Mazon Creek, IL, and opened this one about an hour ago. I’ve been looking at pictures online of jellyfish and have seen some loosely defined like this nodule, though this is probably just a regular old concretion. What do you think? Thanks! P.S. In hindsight I realize that wetting this nodule down wasn’t particularly helpful lol
