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

Hello, I'd love some identification help on this lil ammonite fossil I purchased at the Tucson Gem Show. The dealers were Russian and all the info I could get was that the ammonites were Russian as well It is a bit pyritized. I bought 2, I used the larger one to make a mold and cast. The original did not survive the process so I have included pics of the cast (the one with the loop added, lol), I think it's easier to see details on that as well. Additionally, if you have any rec's for online or in print resources for ammonite ID they would be much appreciated. I found myself googling around in circles trying to find info to ID this myself. Thanks in advance, Maranda

I purchased this from someone who said it was a Hexagonaria coral found at the Rensselaer Quarry in Indiana and it is covered with a coating of calcite and pyrite crystals. Can anyone verify that this seems to be a correct identification?

Hi everyone! I acquired this in an estate wholesale with a bunch of other ammonites (mostly Moroccan and Madagascan). This one caught my eye immediately as I don't know how to id it or even where it came from (I think it's Russian just by comparing it to pictures of other pyritized ammonites but I'm not 100% sure). The interior has been completely pyritized and some of the aragonite shell remains which is pretty unique. Any help on where this could have come from, age, and genus would be greatly appreciated.

Your Guess is Better Than Mine: Fossil Calamite? Scaled bark? Animal? ( Missouri )
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian Formation: ???? Hello! it is I once again I was curious on what this might be as it looks different from what I usually see in this type shale I have found Pyrite Calamites in shale but they usually don't have this texture so I was unsure of what exactly it may be. Zoomed in picture of the texture: Other side of this shale: Not Sure if these will help with the ID but here is the picture with the end pieces visible also for those interested here is the pyritized calamite I found near this: -
I recieved this ammonite as a freebie with another, larger ammonite. It is pretty tiny, maybe .7 inches across at the largest. Can anyone identify the species, so I can label it on my shelf?

Saturday the Paleontological Society of Austin visited the "Waco Pit". For those of you who are not familiar this is a very large borrow pit from which the US Army Corp of Engineers dug material for the building of the Lake Waco Dam here in Central Texas. The pit exposes the Del Rio clay which is part of the Washita Group, Lower Cretaceous (earliest Cenomanian Stage). What makes the pit special is that it produces a really interesting micro fauna along with the normal sized fossils common at other locations. The microfauna includes lots of tiny pyritized ammonites and other mollusks. When we (daughter and a friend) left Austin it was drizzling and foggy but despite the serious threat of storms we stayed dry the whole time. In fact the cloud cover and breeze made for a nice day. But lord it was still muddy. The clay sticks to everything and for every ten steps you pick up 10 pounds of muck. As you try to pick up the little micros they would get covered in mud and you just hoped the ball of clay you slipped into a bag still had the fossil with it. Rinsing it all off after getting home was fun since it was like finding them again. Sorry I don't have location shots. Being covered in muck I was hesitant to even touch the camera. Here are some photos of the variety of stuff. My two best finds are the nice shark tooth and the Rhyncholite. But there are also plenty of good to decent ammonites and other shells.

Hi, I'd like to ask for a destination. I think the partially pyritized sample is Ortoceras. I also see the undressed part of Omnia Superba there. And I can't handle the trilobite, also stripped headless. Is the order of Calymenin possible? Ordovik - Czech Republic

I have come across, for sale, a pyritized agnostid trilobite from the Wheeler Shale. I was curious if anyone had seen these before, and if so, how susceptible were they to pyrite disease? It's quite a nice specimen but I don't want to waste money if it's guaranteed to rot in a year or two.

From the album: WhodamanHD's Fossil collection.
Im not sure the species or where it came from.
