Hello together, I just bought this thing online labelled as a septarian nodule with pyrite. From Germany, no further info. It looks quite fossilish to me, maybe like an ammonite? I just cant see exactly what the pyritized "ribbons" may be. I do not have it yet, so sorry, no scale. Size is 10x8x3cm. Any ideas? Thanks, J

I don't know what this is, but I'm sure I NEED it! ID help please.

Found this curious stone while walking a creek near Cayuga Lake, NY. My boot is shown in photos for scale and is about 30 cm. The creek is carved down through various layers of the Hamilton shale group and seems out of place. There is an outcrop of Tully limestone further upstream from where I saw this beauty but is lighter brown. I am unsure of what type of rock (Tully limestone?) it is as it was dark brown in color. I observed many dark brown boulders and slabs along the creek too. Could this be a nodule of some type and what do you think might be inside?

My bucket of mazon nodules collected this summer have been sitting outside in the sub zero temperatures all winter. I was finally able to fetch the bucket and thaw them out recently. The nodule presented split completely different than other nodules that have opened. This one is a heptagon prism, VERY geometric, not split on a horizontal plane like I am used too . Is there a fossil present on the upper surface and have others experienced nodules opening up geometrical like this one? Thanks for looking Mike Front view Back view.

Hello, Any idea what this might be, where from? Possibly a madagascar fish nodule? The seller just says "probably cretaceous", doesn't seem to know much else. 13cm length. Also while I'm at it, can I ask if any part seems restored or enhanced? Thanks.

I was splitting open some Mazon Creek nodules I've had for a while about a half hour ago when this enigma popped out, I have no clue what it is. The nodule is from Pit 11.

Need a little assistance identifying this. THANKS!

Picked up two large items the other day. I figure they are large ammonites but the disks toward the bottom on the cleaned up one are confusing. They would be bilateral equal except for the break in the one. The second is about 125lbs and has an dark orange/blk pattern showing thru in areas that appear to be shell. Neylandville Formation, Hunt County TX

Pic one is how it originally presented. The rest show it as it looked being uncovered. It broke into sections and many parts broke off when removed. Have all parts isolated and somewhat cleaned off. Will attach those pics soon. Anyways, I have no clue what it could be. Found in Hunt County, TX three days ago.

Perhaps one of the Mazon Creek experts could help with the ID of this Was sold to me as Mazon Creek Pecopteris Look a bit different to the usual Pecopteris that I have seen

Ku2 Hunt County, TX This is about the size of a car tire. These are typically heavy in mineral deposits on their interior with some perceived chambering. I've recovered quite a few over the past year that are very similar but none I've ever come across have had the exterior features like this one. It also carries that same orange color that I'm observing in a lot of the collected items. (Collage pic is of two others examples of the coloring referenced.) I've been pointed towards septerian nodules before with a similar submission. I've read some of the research on them and while some characteristics fit, others do not. It's heavy enough that I opted to go with the one-sided picture and see if there was an interest first before q flipping it on the other side and potentially damaging some features. The bivavle, Exogyrabivavle ponderosa I believe, was found nearby. It's about 8" at its widest point. Thank you

A Mazon Creek nodule popped open a few days ago. At first I thought it was nothing. But in the right light, I have hope (hopefully not false hope) that this may indeed be a find. If this were my Ordovician matrix, I could envision a trilobite. Maybe it mimics a horseshoe crab!!!! During my hunt, I did get to see a horseshoe crab found by @flipper559 I will cross my fingers waiting for the experts to respond.

I've had this for a while but don't recall where I got it. Someone probably gave it to me - without data as usual. Is it one of those 'pseudocoprolites' from the Miocene Wilkes Formation of Lewis Co, Washington? Or do things like this occur elsewhere? Are there any confirmed coprolites that look like this, from any place? If not a coprolite, what is is composed of - limonite, siderite? @GeschWhat

Hi all! I have been using my new scope and camera to get some better photographs of conodonts I've recently found in nodules in Pennsylvanian Stark shale between Winterset and Bethany Falls limestone. I have found 4 of these 500-700micron, tooth-like structures-I destroyed several inadvertently removing the "carbonized film". Two of the 3 most recent are not connected to anything, but have a broad base. In the 3rd photo, you can see what appears to be a joint where the "tooth" connects. I am waiting on finer needles to clean this one. Though I call them "teeth", I don't really think they are-they are not conodonts that I can tell, and in a couple nodules, there are other "carbonized" pieces present (you can see portions in photo two). I think these are really cool!!! If anyone has even a thought about what they could be, I'd appreciate it, as always!! Bone

Hard to identify material in phosphatic nodule? Piece of a crustacean? Coprolite? (Missouri)
Samurai posted a topic in Fossil ID
Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale I have been going through some old nodules I had collected from when I first found an area full of these nodules. I happened to find this and was unsure of what it was due to how it was sort of "Shiny" for lack of a better term. I also have some other different phosphatic nodules with similar features and would love to post them here if anyone is interested. I ultimately wish to have some sort of identification for these materials. Some sort of inclusion in this section so maybe it is possibly coprolite? I do not know- 3 replies

Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale Hello! I found this quite some time ago and did not know what sort of fish material it could be. I am fairly certain it's something fishy as I have found plenty of chondrichthyan teeth, body parts, bones and a few fish coprolites during my nodule cracking adventures.

Looking for unprepared ammonite nodules or similar pieces
mattbsharks posted a topic in Member-to-Member Fossil Trades
I am looking to trade for some unprepared ammonites, ideally multiples or pieces with other shells on them as well. I have no real preference for the location, and they do not need to be rare species. I can offer shark teeth of all different kinds, megalodon, hastilis, great white and most other species. I also have some mammal fossils and lots of petrified wood. I would post pictures of all but I am away at University for a couple more weeks, and am hoping to arrange a trade for when I get back home for the winter. -
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.

Does anyone recognize this type of nodule? Found at a lake beach near Granby CO -- upper tertiary/grantitic rocks (minor mafic)/ metamorphic rock boundary. Total long axis of the nodule is ~3 cm

So I live near the Mazon creek and have found many fossils in my yard but this one has be puzzled. Most if not all of the iron nodules I have found have been smooth and oval or rounded in shape, This one has bumps all over it similar to some species of tree branches. it is long and round and heavy for it's size and the typical color of most of the iron nodules I have found and opened. But I have never seen a long one like this. Hopefully I got the size right on the photos, and I do have much higher resolution photos. Found lots of grass and ferns and a large piece of coral as well in the past. Along with lots of coal. The area where is live was once a very large strip mine area so the spoils were piled all over and if you dig you will find something almost every time. Edit to add about 6" long and 2" in diameter.

hey does anyone have any good tips for prepping a fish nodule?

This is a Septarian nodule aka lightning stone that I dug out of a pond dig. The end has been ground and sanded and polished as my focal point. Clay harden into siderite and cracks filled in with calcite. #1 is the bottom side.
