I’ll start off my collection with the most common ammonite you can find on the Yorkshire coastline in England. Dactylioceras Commune Lower Jurassic, Upper Lias. Roughly 180myo You can find these ammonites in abundance in Whitby. No exaggerations when I say iv seen thousands over the years. You can find them in plenty of other locations all over Europe, though they’re most known as the Whitby Dac. Now, while they maybe common, size comes into play with mine. You’re usual dac, will probably be between 2-3 inches. If you’re lucky, you can get a 4 inch one, though uncommon. map imagine my shock, when I found a monster with its keel poking out. It takes something special to get me excited about one these days, and this one did just that. After prep, I measure from mouth to keel, and it came in at 5inches to the dot. With the mouth hood preserved, and as good a middle as you’ll get, it’s safe to say you don’t get better. Iv asked around and have yet to see one bigger, though I can guarantee, I’d say this may be the largest Dactylioceras Commune to come from Whitby to date. I hope you enjoy my collection as I post them, as much as I do. Thanks for reading. Dan

Authentication of Customers Fossil - Dactylioceras
FossilizedJello posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey all, its been a while since ive been around but fossil season is finally here in NJ! I recently sold someone a chunk of Dactylioceras ammonites from Germany. Its not the best piece but I thought he got it for a good deal and they are harder and harder to find. Now he sent me a message saying he does not believe it is a fossil. So I hope I am okay for posting this here. One of his concerns is the little residue in some places but I believe it was slightly used to preserve better in some spots. Thought it would be decent to post this here.- 8 replies

The ones I know are the crinoid plate, knighta, PA fossil fern, dactylioceras, random ammonite, two moroccon trilobites. However, I have no idea what the middle yellow like imprint is nor the two species of black trilobite in shale. And then the two upper left fossils have me clueless. Wanted to know what they are before I consider buying. Thanks again for any help. Again, no location or collection information.

I've got the assignment to identify and collect data on these three ammonite fossils. My best guesses are that the first two are from Ceratites and that the third one is Dactylioceras. The first two are about ten to twelve centimeteres in diameter, the third one about eight. Since my School is still closed due to the current situation, these are the only pictures i have got.

I recently found a rather large Dactylioceras ammonite from Saltwick Bay in Yorkshire UK. If measures around 4.2 inches which is pretty big for the species, although iv seen bigger. It was a reasonably easy prep and the matrix pulled away like it was nothing. Unfortunately there’s a small section missing from the outer whorl, either predation, or compression from fossilisation caused this. Still a lovely specimen. I’ll be posting plenty more soon, Iv been concentrating on building an online store and constantly prepping over the past few months so hardly find the time along with work. Thanks. Dan.

Dactylioceras ammonite: glue?
aplomado posted a topic in Is It Real? How to Recognize Fossil Fabrications
Does the green stuff look like glue to you? Any way to tell if it is just repaired or a composite? Edit: seller confirmed that he though it was glue also, though he did not know if it was repaired or a composite.- 5 replies

I recently bought this piece from online and am uncertain of its authenticity. (But not very worried - it set me back less than $10!) It looks very much like the Dactylioceras ammonites coming out of the Posidonia Shale that I see online sometimes; however, up close, the shimmer appeared suspiciously similar to glitter nail polish. I tried a little acetone on one of the small back ammonites (third photo) and the gold dusting came off easily. There doesn't seem to be any depth to the positive fossils; where the plate is chipped, there just seems to be shale underneath. There are also tons of tiny ammonite impressions on the front but almost none in back. On the other hand, pieces like these are inexpensive, so would it be really worth the trouble to forge? Dimensions of the piece are about 13cm across, 1cm deep. Thank you for your expertise! I'm learning a lot from this forum. Happy to post more photos if necessary.

The shell is pyritized and the septa of the phragmocone are filled with calcite. More or less complete specimen.

Hi Everyone, I purchased this ammonite from a shop in Colorado several years ago. The only identification they provided was that it was an ammonite from Morocco. I believe them because the opening has been cut flat and filled in like ammonites from Morocco typically are. I have tentatively identified it as a Dactylioceras but I'm not sure, another possibility could be Perisphinctes. There also could be other possibilities, too. Since I don't have information on where it was collected, I don't know what age it comes from. I think I read an older post on this forum that the ribs on Dactylioceras only split in two, but on Perisphinctes they sometimes split into three, but I haven't been able to find that post again (Ludwigia, I seem to remember you were the one who made that comment). This one looks like some of the ribs split into 3, which might suggest Perisphinctes. Also I've included a photo showing a suture line, which I understand can be used to make an identification, but I haven't found anything on the web that gives examples of suture lines for different families. Can anyone help with the identification? Thanks for the help, this forum is amazing!

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.
