In 2013 I was visiting around Buffalo and went to a creek that had been recommended. I didn't come across any trilobites but did find other exciting things. Among them were quite a few pyrite nodules I dug out of the creek bank. Must have found 30 of them. All rounded but varied shapes. About the size of a quarter or a little bigger. I have learned that many people have found them. Some close-ups. Many have a hole in them (shown above) and you can just barely see something inside the hole. Early on I broke some of these open and found... ...pyrite fossils. Gastropod, brachiopod, clam, ammonite. I quit there, I didn't want to smash them all. Over the years, as many who have found these know, some of the nodules began to decompose. What some refer to as "pyrite disease" or "pyrite rot". I have had a number that have broken apart and then turned to dust within a few years. I quarantine those that show signs but haven't had to in the last year or so. I have stored most of my nodules by simply putting them in a sealed container with a desiccant packet, with only a few problems after 7 years. But some ...the first 4 pictures of the post... I keep in a Pyrite display case and they have never shown any signs of problems. And the mini fossils have also never shown signs of decomposition, either. And they are on display as well, not packed away with a desiccant. So...some from the same "batch" decompose while others don't. Why??

I finally got some time off and had a nice day to hike the North Sulphur River Texas. I hit the fossil park which is the most hunted location but I still managed to find some good stuff. The big piece of coprolite is loaded with shells in it. I really like the well preserved Glyptoxoceras heteromorph ammonite and the big Tylosaur vert.

Split ammonite saligram from India
Roodahg posted a topic in Is It Real? How to Recognize Fossil Fabrications
Thank you for taking the time to read this post. I am taking time during the lock down to have a declutter and I came across this small ammonite in two halves I purchased in India some years ago. I have no clue about its authenticity but I seem to remember the seller telling me it came from a riverbed in Nepal. Let me know what you think, I believe it is a lovely little object - perhaps a paperweight if nothing else! It was bought in a not particularly touristic town in Karnataka state, in a shop selling religious artefacts - take from that what you will.

I hunt fossils in gravel from creeks and the likes. According to the geological survey of similar gravel the age ranges from 200-400 million years ago. I was wondering if you guys could tell me if this was an ammonite or some other sea gastropod. I've found countless other types of fossils but this is the only one like this.

Sometimes I find things in nature on my own, sometimes I purchase things. This I purchased at a fossil and mineral show. I believe it's important to support such shows to keep them going. This is a nice ammonite, I guess some 165 million year-old I suspect this one is from the Jurassic period--it was collected in Madagascar. I've brought this little guy to some small classes I used to teach. It is about 9 inches across.

Once again I slack in posting things on here. last week I decided to dig out a very large ammonite I found last year. It’s a Phylloceras Heterophyllum. Quite rare around here, and to get one as big as this is, is even rarer. It weighed an absolute tonne but worth it. All the prep work is done, all that’s left now is to rebuild some small sections and cracks. It’ll be a stunning piece once’s finished.

While the world is shut down, people can crochet their own ammonite at home.

I made my second trip to the North Sulfur River today. I had planned on going yesterday, but it was pretty chilly early, and today was forecast to be much warmer, plus the water was still coming down, so I settled for a 50 mile bike ride yesterday, and headed for the NSR this morning. I seem to be making the most of this time of social distancing / off work. A bike ride yesterday, NSR today, and I'll be crappie fishing tomorrow. If this is a preview of retirement, sign me up. Once again, I just went to the Ladonia Fossil Park. I hiked downstream, the opposite of the direction I headed last time. I'm still finding out what my physical capabilities are for this kind of trip. With all my bike riding, my legs are strong, and I'm in great aerobic shape, but at 69 years old, and after almost 50 years of heavy machine shop work, my back and shoulders are pretty cratered. I'm not sure how I'll hold up for long hikes down treacherous river bottoms, or climbing in and out. I probably pack my backpack lighter than most here. But after hiking a couple of miles down the river and back today, I feel fine. So, maybe I can hold up to these trips better than I thought. I'm ready to try getting in and out of the river at some other spots. I drove over to the FM2990 bridge and looked at that access. I'll tackle it, but I'm definitely going to do it on a dry day. That rope climb back up looks tough. I'd also like to try out the river downstream at 24. A question for those who know the area: Google satellite photos show a lot more water in that area, with hardly any sand bars showing. Is the water that much higher there, or is it just when Google took the photos? Do I need to wait for lower water to try that out? Water level today was 2.08. I didn't bring that much back today. There was nothing of real significance, but as always, some interesting stuff.

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.

A few months back I was exploring a new stream in New Jersey and stumbled upon some matrix where I found this Ammonite. I am not too familiar with NJ Ammonites. Can anyone help identify this particular species? I thought it was pretty cool.

Hi, my son and I have a large collection of fossils, some of which we found ourselves on the Jurassic coast of England. As we are now mostly confined to our houses here we were hoping to better document our collection and we were hoping to put the correct names to them all. To start I was hoping that someone could help us out by identifying which ammonites these are. They were all found in Lyme Regis and they are all preserved in iron pyrite. Thanks.

This is an ammonite out of an old teaching collection. Can some one help me with an identification? The tag (which after 40 years may not be the correct tag) indicates Prionocyelus, Niobrara Formation Albany County, Wyoming. The ammonite is 2.1 inches in diameter.

Here’s my crystallized fossils, enjoy!! All of them so far Ammolite from Alberta Ammonites from Madagascar

I was in Moab, Utah last week and stopped in at the Moab Rock Shop. They had lots of fossils so I picked up this nice little ammonite about 17 mm diameter for a few dollars. It was labeled as an Orthosphinctes from the Jurassic of the Atlas Mountains of Morocco, but I'm not convinced. I can't find much online about Orthosphinctes but what I do find shows the whorl cross section as being much more oval in shape. I found the thread below from 2014 but it doesn't seem to have answered the poster's original question of Orthosphinctes vs. Perisphinctes. Can anyone help?

Hello all I was wondering if any of you could identify this very tiny (1mm) ammonite sitting on top of some Dactylioceras athleticum from the Jurassic of Schlaifhausen, Germany. Can this be a juvenile stage of the same species? I know nothing about the different lifestages of ammonites. Looking forward to your answers. Edit: does someone knows the size of the smallest ammonite recorded?

Hello My question is not so much about the process of prepping & polishing Ammonites as it is about the Ammonite Fossil itself and the outer shell. I can see there are dozens of different techniques and philosophies about this process, but the question is: --> Can "almost" any Ammonite be polished if you remove the matrix or does the shell sometimes absorb too many minerals and become like the surrounding rock and it just remains dull ? A lot of the Ammonites on our property seem to be encased in a white limestone matrix and are very dull looking. They "appear" incapable of being polished, but I haven't tried yet. Just curious... I hope this question makes sense. Thanks in advance, Mike The photo below is not one of my Ammonites, but is a good representation of what mine look like. I'll try posting a few of mine later. Thanks Again

Dinosaur ? (Marine reptile?) skeleton discovered while ammonite hunting in central Oregon
TheNecromancer13 posted a topic in Fossil Hunting Trips
2 days ago I was digging for ammonites in a road cut in central oregon, and happened across some very large bones. I will be returning to the site with a team of NARG members and affiliates to excavate it in a few weeks. Super exciting find, there are at least 6 bones exposed, probably many more yet to be found. The ribs are 3 inches thick, so probably at least a 20 foot animal. This is by far the coolest thing I've ever found.

Hello everyone, I recently found an ammonite in a nodule I collected at Monmouth Beach a few years back and am thinking of prepping it. It seems to be some kind of deathbed as there are (or were ) 3 ammonites in the rock and it seems to go through the entire nodule. However, I’m stuck with a rotary multitool and have close to 0 prepping experience with it . The only things I know are to turn the speed down when prepping near the fossil and turn it up when removing rock. Any help would be appreciated. Thanks.

Hello everyone, I recently started to consider prepping some of the ammonites I own but something’s really been puzzling me. When I’m splitting rocks at Lyme Regis, the ammonites have a negative impression which is sort of orange but when prepping, you can see that it’s a very thin layer that flakes off. I’ve seen many preps that have left this on and many that have taken it off. What is this orange layer? Is it shell? And should it be left on while prepping? I’ve left a picture found on the web below. Many Thanks

Hi all! A bit of development to the Frozen fossils topic. It's the same Moskva river Bronnitsy Oxfordian, but some 5km upstream, where you can find a bit younger layer of Amoeboceras serratum ammonites (earlier it was Amoeboceras alternoides layer/zone). The difference is mainly in the keel, it's less pronounced. The layer is accessible only in winter. Dont expect it to be breathtaking, the preservation is unfortunately worse and the fossils are more scarce. The shore:

Ammonite plate - real or fake
Rvald005 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! i posted a different real or fake question earlier (brittle starfish) and was told It was fake and to keep looking for other gifts. It was suggested that it’s better to be safe than sorry and to post other items I’m interested in. Since i really appreciated the input last time, I’m here to ask again This time it’s a zoom in of an ammonite slab (holzmaden shale from Germany). It looks real to me but I just wanted to check. Thanks for all the help in gift searching!!
