    Madagascar fish nodule

    Some time ago I bought this unidentified Madagascan fish online. Any ideas what species it is? Thanks

    Coprolite, or pseudocoprolite?

    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

    Shale nodule teeth or chelicerae?

    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 reall
  6. 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 thi
  7. 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.

  9. 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.
  10. 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.

    Weird Iron Nodule

    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

    Fish in a nodule needs ID

    Hi All, I bought a fossil fish on online a while ago. The seller identified it as "PTERONISCULUS Fish fossil Trias 250 mio Madagascar" It would be nice to confirm and also get additional information on possible locality, ideally reference to a scientific publication. I'm really curious about in situ conditions where the fossil was found. Could it be desert, or a mine. It seems like the fish nodules are not that rare if you look on-line but it's hard to find anything about the place of origin. Clearly, recognizing a fish species in this condition is a rare skill. So, ma
  14. All, I wonder if someone may have an opinion about the object(s) in the small nodule shown here? The entire nodule is about 0.63 inch wide x 0.75 inch long x 0.5 inch thick (1.6 cm x 1.9 cm x 1.3 cm). It came from an area of shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The shale from this location has many fossil marine invertebrates. I'm assuming its a mineral formation, but any thoughts would be appreciated. It is very hard to get the 3-D relief to show up in photos, so several angles and lighting conditions are shown. Best wishes.

    Nodules on Fossilized Bone

    What are the round nodules on this piece of fossilized bone? I suspect there is some lichen on the top of bone on photo 2. These run in size from 1mm to 5mm. Any ideas?

    Opened mazon creek nodule

    Hey, i just opened a mazon creek nodule with my hammer with a few light taps (since a month going in and out the freezer didnt seem to work) and i found these balls inside. Are they the actual fossil or are the specimens inside the ball? Any answer is appreciated!

    What do you think this is?

    This isn't a recent find but one that i labelled two Cyclus but going back to it i don't think the other fossil is one. The nodule came from a Derbyshire , UK opencast that has now been reclaimed . It was a very productive site with a good spread of flora and fauna. Thank-you for looking John

    Unusually smooth nodule

    I found this half of an open nodule last September when I was hunting at Mazonia Braidwood. It was covered in dirt so I took it home to see if anything would show up when I cleaned it up. The dirt rinsed off easily and I was surprised to find a layered, smooth surface on the inner half. The feel and patterns of colors remind me of the inside of a shell. Has anyone seen this before or have any ideas about what this is?

    Fern ID

    So I got this Fern nodule yesterday. It came with no info. Approx 6 cm Any ideas?
  20. Thought this would be an interesting one for anybody overseas, who has never heard of Yorkshire’s Golden Cannonballs. Theyre only found in the UK along the Yorkshire coastline. With a 1/15 chance of having something inside, it’s safe to say they can be quite rare, and are always sought after. More often than not, they either contain one, or multiples of Eleganticeras ammonites inside. I’ll never tire of finding them. Theyre found in the shake jet rocks, and take hours to polish up the iron pyrite to give them their golden glow of you like. Here’s one I recently prepared.

    Unknown orthocone

    So I have partially removed an orthocone from a nodule that I found in some eroded glacial till. The rock is most likely silurian in age but I can't don't recognize this orthocone. It seems to have faint striations running lengthwise down the shell, which I haven't seen before.
  22. Howdy all, I tried searching for answers on the search bar, but couldn't find anything, so I'm hoping someone can help me out. I was going through the fossil prep section and noticed that many people seem to start off with a large nodule and remove all the matrix to reveal the fossil hidden inside. My question is, how does one (a seller, or person out on a fossil hunt) even determine that a big hunk of nodule has a fossil inside if there are no immediate visible indications of a fossil from the outside? Once again thanks.
  23. I have a few nodules that haven't split from my Mazon Creek trip in early March. They have been through I'd guess 20-30 freeze-thaw cycles by now. I have been getting impatient, so I decided to whack them with a hammer and chisel. I've smacked each of them like a dozen times, but they still won't split. It's not obvious where the bedding plane (?) might lie, so I've struck them from all sides to no avail. Is this an indication that there is nothing inside, and therefore no bedding plane?

    Unknown Mazon Creek

    Hi! I just recently found this piece for sale, with no identification. The bumpy texture made me think of Arthropleura, but could also be something like a Stigmaria root. Please let me know what you think!
