Picked up this double chert nodule a while back and have been alternately freezing and thawing. Finally broke in half between the nodes. From what can be seen is there value in continuing the process to break into the halves or is if hammer time?

I was able to get out one day this March and collect some Mazon Creek nodules from Pit 11. I found all these as they were and all of them were weird enough to keep. Any help with ID's on any of them? Even if some aren't fossils I thought they were at least unique compared to the many solid dud nodules you find with the freeze/thaw process. Thanks! 1. 2. 3.

Request ID of Fossil shell encrusted geode/nodules Pryors Montana
Oxford posted a topic in Questions & Answers
Thank you for viewing this post. Found a group of geodes/nodules that are covered with small fossilized shells. They were found in the southern part of the Pryor mountains of Montana between Bear Canyon and the Dryhead. Has anyone seen similar rocks, do they have a name, or know any other information about these? Thanks again.

Hello! I have got this nodule from Lyme Regis and was wondering whether this looks like a good nodule to contain a fossil and how you can tell from the outside? Thank you in advance!

Had a few nodules pop from my winter nodule stash from pit 11 collecting. Wondering if anyone has ideas? Don't know if they are animals or suggestive mineral staining? from left to right: 1. jellyfish? 2. worm? 3. jellyfish? Something from the plant world? Sphenopteris? Thanks!

This is a Pennsylvanian age Mazon Creek type nodule found in Indiana.It may be plant material that is decomposed beyond recognition but thought I’d post it to see if anybody thought otherwise.I haven’t found any fish scales in this location but wondered if this might possibly be a scale.

Hi everybody, lately as I read topics on the forum about crabs, the word crab nodule appeared in several thread. I think I get how nodule works, and was made but I can't stop wondering about the following question : Is there nodule in every sedimentary formation or can you find nodule only in a certain type of "rocks" ? I went in japan on several fossil hunting trip and I never found or see any nodules. Maybe I looked at the wrong place... Do you have any tips for finding nodules ? Thank you very much, David

Very Unusual Megalodon In Phosphate Matrix Specimen - I Need Some Advice
Fossil_Rocks posted a topic in Fossil Preparation
This tooth in matrix has been sitting on a local diver's desk for about three years, under a dust cover, and has remained very stable. We think the matrix is essentially a phosphatic nodule. It's basically a piece of the ACE River Basin river bottom, and obviously it's an amazing specimen. I wanted to prep. it using a hardener, but I've never prepped any fossils before, and wasn't sure which product that I should use. I've heard of Butvar, of course and know people use it on bone, but this isn't bone, it's more mineral. Should I dip, or brush? It would seem a lot cheaper to brush it on. I'd also like something that would be water proof, afterwards. Any thoughts or ideas would be greatly appreciated. I'd also like some direction on a reputable seller of the product. Any folks here in that biz? If you are, then I'd rather throw the biz to a member, but I will need the product over nighted to me. I want to do the job myself, and I won't be doing a lot of prep. work, so I don't need a ton of the stuff, just enough for this one piece, which measure's about 10" in length. Here's a list of products that are advertised on a site called PaleoPortal Fossil Preparation. - http://preparation.paleo.amnh.org/47/adhesives-and-consolidants Solution adhesives which set by evaporation of a solvent and include:Paraloid B-72 (ethyl methacrylate co-polymer, formerly called Acryloid) Butvar B-76 (polyvinyl butyral, or PVB) Butvar B-98 (polyvinyl butyral or PVB) McGean B-15 (polyvinyl acetate or PVAC, formerly called Vinac B-15) “White glue” dispersions and emulsions (e.g. Elmers, Rhoplex, Lascaux) - Not Waterproof, so not my choice Thanks in Advance, guys ...

Ok, so I collect at the same spot frequently, so I often run into some oddities. Whenever I have a question I simply pop it up on here and usually get the answer or ID fairly quickly. Members here have been fantastic at helping me with my collecting. now I have come across two things that are fairly bizarre to me at least. the first one is a concretion, pennsylvanian I believe, that I am not sure what it could be..any help here would be fantastic.. the second thing I have is from the same place, near turbotville Pa. and its got me baffled, because its a very nice concretion with a trilobite cephalon, however there is something I have never seen going on here...it almost appears to have a horn or smething sticking out of the glabella....yes there was a second one where it seperated on another plane, but I already glued it together, so there is two of these things.. Heres a picture of the bottom portion where the glabella popped off of the bottom lip if you will......you can see the lower markings where the genal cheeks (for lack of knowing the term, they arent spikes lol) are located.

Hello everyone, I have trouble identifying this fossil which is unlike any I've found in siliceous nodules of Šárka formation (LLanvirn) in Czech Republic. At first I thought it's a fragment of a Conularia, but the shape and structure's not right. I have found only this piece, but it seems to be part of a larger organism or colony. It reminds me most of a cast of colony of barnacle-like organisms. The size of the structure is 3x3 cm, about 12 mm in height. Any ideas? Thanks Ondrej

Not a fossil but found this interesting surprise in a spoil pile nodule. Photos don’t do this specimen justice. It’s best viewed in direct sunlight in order to see it glisten.I believe this is rainbow pyrite drusy.The last photo is another “nodule” that has the same exterior appearance as the drusy nodule. I’m open to any suggestions as to how to expose a pyrite drusy seam in this stone. It spent last winter freezing and thawing.I can’t remember for certain but I believe the exposed specimen went through freeze and thaw cycles but was also struck with a hammer.

I'm hoping someone can help me id this. This one popped open this morning and it's not like any of the normal ferns or plants I have from Mazon Creek. It's roughly 5" tall, Thanks for looking

Unkown Crystallized Fossils In Chert And Flint - South Texas
Piedras_de_Tejas posted a topic in Fossil ID
Does anyone know of a specific name for flint or chert nodules containing quartz-replaced fossils? Also, do these form in a particular formation or did they develop in several in the presence of dissolved quartz? i have found these in many areas around san antonio and they're my favorite to encounter. The first pic resembles tube worms to me and i have no clue what the fossils are in the second two images, but the one that appears as dozens of adjacent, long, parallel columns comes up often in my area.

I got out to the Braidwood fauna area last week. I found this half nodule just as it was and wondering what this is? Bark impression? I definitely found a lot of petrified wood and plant stuff where I went so thought the bark idea. But haven't seen anything like this before... Here's the finds for the day.

I recently got round to prepping a few ammonites from my collection - I collected them during the summer (August) at the Yorkshire Coast (UK), but have only just got round to prepping them. I thought I'd share them with you. I'm not an experienced prepper, so I was practising on these ammonites. I am pleased with how they turned out, although I still have a little bit of work to finish some of them off. If anyone else wants to share their Yorkshire ammonites that would be great; once we get a thread going I'll post some of my other specimens. All of these ammonites are from the Lias of the Yorkshire Coast, UK, and were prepped out of hard limestone nodules. I used the Chicago Pneumatic from start to finish on all of theses ammonites, and then I gave them a light coat of beeswax.

Quick prep video of a nodule from the Upper Lias of the Whitby area I did the other week if anybody is interested.... http://www.youtube.com/watch?v=FMN1J6O-NEM&list=TL9fjxRxte4kno0x5ZseozgaSIbp8eJv0q If you happen to read this Jonny, note how thick the pyritic wall of the nodule is and that is why you need a TT when working on this sort of stuff especially if you are trying to remove it.

Gotcha! But seriously, this is one of the nicest "turtle shell" septarian nodules I have found. It's from the Mississippian of Kentucky. It's 5" across (13 cm). I think it's being eaten by a starfish.

So I am likely way off base with that guess, but today I cracked open yet another small nodule with a little (5-8mm size of the actual fossil) circular fossil in the middle. They appear to have small scales or sharp edges which made me wonder if they are some kind of seed or spore. Maybe even a fish scale? They came from the same site as my other Pennsylvanian finds (old Chieftain Mine in Vigo County, IN). I'd appreciate any insight anyone may have as to the identity of these fossils. -Andrew

I'd better post this before a new weekend arrives . Last Saturday, I got out to a "new" outcrop of Juana Lopez and Carlile Shale (Turonian). The day started out with another pharyngeal fish tooth (I still don't know what species)... ...followed by some awesome Prionocyclus (sp.) ammonites still in nodules... ...I was able to carry the smaller back to the truck, but had to return with a dolly for the larger (100+ lbs.)... ...after getting this big rock home and giving it a scrub, I decided to leave as is... ...I don't find many large nodules with the ammonite intact (or even visible), so this is a gem. Hope everyone has an excellent weekend, happy hunting. -P.

Which way is up? Is there any convention for guessing which way a crab is oriented within a nodule? It would be desirable to prep "down" to reveal the carapace, leaving the ventral aspect encased in the matrix. But which surface is the correct one? Of course, the "right" choice is a 50/50 shot, but is there any way to improve those odds?

Picked up a few little Muncie Creek nodules, just for something to do. Expecting (or at least hoping) to find some conularia, they were all pretty much a bust, except this one. It was a very small nodule, but has a very distinct something inside. It really looks like shell, but the 'tri-hull' shape and the amount of apparent growth lines is kind of throwing me. But then, I know very little other than the most common stuff. Any ideas? A sort of panoramic view: Thank you! Steve

AMMONITE gender THAT IS - Could this nodule of Eleganticeras elegans ammonites be a male (microconch) and female (macroconch)? The larger ammonite (that I think is a female) is 3" and the smaller "male" ammonite is 1.5". I thought this was a real neat nodule when I got it and it would mean a lot more to me if my hunch is right. It’s Jurassic from England of course and if you know your British Ammonites, I would appreciate your feedback. mikey
