Hello All, Recently, I've acquired a sliced half of the Cretaceous heteromorph ammonite Scaphites. While rarely sliced, I managed to find one buried in a pile of similarly sliced Madagascar ammonites, and purchased it. Here are the photos: 1. A view of the whole ammonite. Here, we can see the phragmocone as well as the sediment-filled living chamber. 2. A closeup of the phragmocone, showing the beautiful septa. The minerals are very pure in this example, making some chambers appear as if they are filled with a tinted glass. 3. The point of no return: the outer whorl splits off from its counterpart, creating the unique shape which Scaphites and its relatives are known for.

It's just an impression, but I find so few like this I had to keep it. Looked all over for the positive but could not find it. It seems so long and narrow for a Bostrychoceras, or is that just an aspect of the impression? 5 whorls visible.

I am collecting heteromorph ammonite and one vendor is offering this ammonite to me. He does not have the id. For me its appearance (i.e. color and shininess) is quite different from what I have collected.

The bad weather gave me time to spend some time classifying. so i spent some time on my albian stuff. Everything has been self collected (surface collected) over the years. Everything is also small, so i chose the screws cases to store them. Everything can be seen on a dedicated galery on TFF : here or in higher resolution on my flickr : here 8 cases... So here we go Ammonites : (3 cases) then crustaceans (2 cases) : Other inverts (2 cases) : And last one : vertebrate remains I hope you enjoy it. that's all for now.

Hi guys, Thinking of buying this nice heteromorph ammonite from this Chinese seller. It originates from Madagascar and I'd like to know what genus or species (if possible) it is? And roughly how old as well. Thanks!

Greetings! I mentioned in another topic, that I will post some of my heteromorph findings and prepwork. The locality is in Hungary, and is an abandoned quarry that produced cement for the local factory. It is rich in fossils, but it was a big underwater slope, and because of this the fossils only found in shallow beds, between redeposited layers of "nothing" and always in condensed form, and the bigger pieces fossilized mainly in fragments. Another problem is, that the compressed marls contains only stone molds, sometimes with slick&slides on them, and the matrix and fossil is hard to distinguish There are some pieces that have the imprints of spines. Here is one that is a big question for me, because the spine is visible, (at least at 1 section that broke out with some luck) but it is only a thin imprint in the stone, and I really like to have some opinions, what to do with it... I began prepping, but if i only touch the stone with the vibrotool, I see nothing what I do onward, because the fine dust completely obscure the spine, so I could work as I imagine they should be, and I fear that I will destroy it (and the further ones) completely, and I am uncertain to try to fake them from the matrix (But it is already nearly the same) so this is one option. Another problem is that I need to remove a lot of matrix, and I have bitter expectations what will happen with the underlying spines... So there is a second option to do nothing with it, but I like more to have a good prepared spiny Crioceratites in my collection, so I will try anyway The first spine from the living chamber is currently "faked" because I do not found the spine imprint yet. The second spine is original (as the stone broke off of it) (the other fossil is an Orbitolina, but I am not shure) The sandy marls are soft and the stone molds that have a thin calcite shells are sometimes found in calcite concretions, the calcite coating is very thin and always damaged. So preparing the material is a challenge. Sometimes the spines are preserved, but always broke off. You will see on the pictures below, that the pieces are extremly fragile. Maybe there is a way to preserve, the spines or put them back while preparing? Here is a remains of a spiny one: Here is some finished or nearly finished pieces: From the softer sandy marls: Freshly found Crioceratites (nolani?): Gluing together the pieces: Restoring the missing part with magic sculpt, and coloring it with powdered stone to imitate the stone molds thin calcite coating. (the color was really hard to match, and I am not satisfied with it, but I done my best with it) The complete piece, prepared: Here is some pieces from the condensed marls: Freshly found Crioceratites (duvali?): Gluing together the pieces: Restoring the missing parts with magic sculpt, and stone chips from the matrix, and coloring it with powdered matrix There are acrylic lacquer applied, so the fossil is better distinguished from the matrix The complete prepwork: Here is another heteromorph, Anahamulina (acuaria?): After prepping out of stone: (need further work) With kind regards

I am sculpting an ammonite which will be hunting through kelp fronds. The ammonite i want to use for this sculpture is crioceratites or something closely related. I like the spines and overall shape. My question is how many spines around each band of the shell? Five or six? Thanks for any help you might provide.

Picked this guy up at a fossil shop in Glen Rose, Texas, supposedly collected locally, so I'm just guessing at the ID since I'm not up on Texas fossils. Pretty worn, but quite big...it must weigh two pounds, and I thought it would make a nice display piece. Before:

I guess restoration is OK up to a point but are overly restored Heteromorphs common coming out Drôme? I've picked a couple up at what seems to be an average price for these examples in this condition. There's some resin between the ammos and matrix maybe as support. Do they often come out broken and are stuck back together? Certainly there is something going on as there is little room twixt ammo and matrix and ammos have been prepped there which looks far too clean to have been done on matrix. I've not yet had time to look for minute resin air bubbles on the fossils but the resin support doesn't look like it was hidden too well. I guess this could be intentional to show or a rubbish enhancement. One is soaking in water at the moment, acetone and UV lights are in my studio so can't do those tests tomorrow tho I might use Mrs B's nail polish remover to look for resin/colouring on the fossils. I'll get a hot needle out too. Rough images with not much info below, I'll take better pics later. Thanks John In an act of stupidity I think this should have been posted in the 'Is It Real' section so admins if you think I have please move. Edited for stupidity.....

I've googled and googled but can't find a definitive family tree for ammoniods/cephalopods &c. I'm looking for relationships between ammonites, nautiloids, belemnites, turrilites etc. Does that make sense? Thanks J

This trip (last weekend) was long overdue, I haven't been to the San Juan Basin in months. I love ammonites, but I snargin' love dinosaurs. Just wanted to share some photos. Hadrosaurine... ...turtle and croc(?)... ...ceratopsian... ...some crazy roots and lamas. Made a detour on the way home for some ammonites... ...with a few surprises, a heteromorph ammonite... ...and a partial lobster! I love weekends!!!
