This ammonite is from Guanling, Guizhou. It’s special in that it is very smooth, while the surrounding small ammonites have ornamentation. Any idea which species is that or why it is so smooth? Thanks!

Hey, all! I’m planning a trip to England’s Jurassic Coast next summer. I’ve researched areas like Dorset, Charmouth, and Lyme Regis. I plan to hit all these in my time there. Any other recommendations or information I should know? I’m excited to explore the area and collect some new fossils!

Hi - first post on forum. I'll be travelling to South Dakota (Badlands & Black Hills) from Kansa City during the first 2 weeks of September. If anyone would have tips on collecting ammonites in the area, I'd appreciate the help. I've collected ammonites in Texas but never found a location in South Dakota. Thanks in advance - Tom

Good time at the North Sulphur River in Ladonia, Texas this weekend. Here are some of the things we found! I’m curious about the gray ammonite (bottom right). I’ve attached a few photos at the end (first two photos) to see if any of you know what the black line is running through it at the bottom. It reminds me of the vein in a shrimp!

Dear fellow forum goers, These past few weeks have been quite busy, but that has not stopped me from going on the occasional fossil excursion. A few trips went by since my last posting and I decided to let some trips accumulate before posting again. On these trips I interacted with forum members @Woopaul5 and @frankh8147. The most recent trip was today, 08/12/18, and was somewhat productive. Frank found what we believe to be a part of a mosasaur brain case, which will surely be in his "finds of the year list". I was not as luck but ended up scoring a small point fragment and a jaw section of some fish. There were also some nice quality teeth that I found today. Other than this trip, I scored some nice finds on a few other trips throughout the two months. I hope you enjoy the finds, as I enjoyed finding them, and have a nice day. Kind regards, Trevor Overall Finds Stream Worn Shark's Teeth

Hi all, So a few weeks ago now I went to the location Carniol in France to look for fossils. And we found lots! Most of the finds are pyrite ammonites, but we shouldn’t leave out all the belemnites and little shell steinkerns we found. All the fossils are from the Aptian stage of the Early Cretaceous, and apart from the belemnites all have been replaced by pyrite. So I've already taken out all the belemnites and rinsed the clay off of each one (they’re looking gorgeous right now!), because their shells are not made of pyrite (and seem not to require any special treatment). By the way, does anyone know why only the belemnites are not replaced by pyrite, while all the other fossils are??? But now comes the question of all the pyrite fossils. All are very small. Some were found already starting to “rust” (I suppose this is due to pyrite disease?), but most are still in good state. Nearly all are still partially covered in dry clay though, and (just like it did with the belemnites) I suppose it will come off very easily as soon as it comes in contact with water. But, here is where I am a little worried: Rust is due to the oxidation (—> oxygen) of iron. And in water there is oxygen too, and more of it than in air. Therefore I’m scared that rinsing the pyrite fossils will accelerate the process of pyrite disease and make them “rust” more quickly. So what should I do to clean the fossils? Is it okay if I simply rinse them off? Or is that a no-go? Or maybe I should do it in a special manner or with specific substances? And, finally, what do you think is the best way for me to handle these fossils so that they “survive the pyrite disease” the longest possible? I know that there are a few ways with some weird chemicals to treat them, but I’m only a kid with limited equipment, money and experience, so I’m not able to do anything too intricate or acquire very funky chemicals. I’ve also read that apparently there are two different types of pyrite? How do I know which one my fossils are, and is there anything I should know more about it? Thanks in advance for your help to all those questions! Max

I found a couple ammonites this summer that needed very little prep. The first is a Pecan Gap fm Pachydiscus travisi, not remarkable for quality of preservation, but rather for presentation. With both impressions and the steinkern found eroded out together, I have “all the pages of the book”, something that doesn’t present often, in my experience.

Hey, I’ve finally spent some time on the Jurassic Coast the last few days around Portland, Lulworth Cove and Lyme Regis / Charmouth beach and thought I would share what I’ve found. Not loads but my own first fossil which I’m pretty proud of even if it’s tiny lol! It’s part of a infant ichthyosaur neck vertebrae if I’m correct. Also some photos of Ammonite imprints on some big rocks and a rock I found and broke open with an ammonite imprint and possible tooth imbedded in it? Also random photos of not sure what lol let me know please what you think.

I recently purchased this chunky ammonite from a Chinese seller on eBay. The seller said it was from Madagascar but provided no other information, and I haven't found any photos of Madagascar ammonites that look like this. The suture patterns are unusual (to my untrained eye), and the body chamber looks broken off rather than cut. Total length is about 6cm; width across the body chamber is about 3cm. There are currently several others like it available on eBay (search for 'raw jade ammonite'), some with more pronounced ribbing. Thanks! I appreciate any ideas you have about this one.

So my wife asked me to round her up some free landscaping rocks today, which I did, but I left the times of coming and going a bit fuzzy so as to afford myself a look at a small, slowly eroding exposure of Georgetown limestone that I found about 15 years ago, and have kept more or less under my hat ever since in order to allow adequate weathering between visits. The bedrock is mostly covered with gravel these days, but the hummocky suface poked through in a few spots, bringing a couple 2 inch Coenholectypus echinoids to hand while doing a surface crawl. Blind mining revealed a few Mariella ammonites as well, all a whorl or 2 shy of keeper status. The beating sun and resulting sweaty brow prompted me to pack it in after 30 minutes or so, but a funny spalling precipice of limestone caught my eye and beckoned a quick whack with the chisel and hand sledge...revealing part of the adult whorl of a hopefully intact Graysonites ammonite, rare in the San Antonio area. 10 more minutes of careful chiseling ensued, going at it lightly from all sides till it popped out in 1 piece! Preservation of steinkerns at this site is not as crisp as in far North Texas, but home town pride makes up for that. Many ammonites into this pursuit, I’m happy to report that blind serendipity can still steal my breath away and leave me thankful to experience the joys that nature can present. Next round, I’ll take a tenured buddy or 2 for the harvest. A little blind sweat equity should prove fortuitous for each of us, give a couple hours of steel driving.

A bit damaged but nevertheless a nice Dactylioceras commune with a length of 14 cm. I found it in the quarry Kromer near Holzmaden (Lower Jurassic). -
Earlier this year, my wife proposed the excellent idea of replacing our sadly leaning stick of a mailbox post with something a little more grand, hewn in stone, studded with ammonites of our own discovery. I had intended to take on this project earlier in the year, before the Texas sun would hit me twixt the shoulder blades like a sledge hammer, but a schedule overrun in my kitchen and laundry room remodeling gave me a late start. Anyway, this project took me longer than anticipated since this was my first time dabbling in stonemasonry. The process took me about 6 weeks in my spare time, starting with research of mailbox height from road level and setback from the curb using the USPS website. Next, I made a design in 3D CAD and had a drawing approved by the Postmaster. Following that, I called 811 and had utility companies mark presence of lines in my yard. I dug a 2 x 4 foot rectangular hole about a foot deep, filled half of it with gravel for drainage, then poured a 6 inch concrete slab, reinforced with rebar. The superstructure is composed of cinder blocks with voids infilled with cement. My boy and I opted for a honkin' big mailbox capable of holding a USPS Flat Rate Large box. "Go big or go home", as they say. My neighbors expressed reservations about the stark gray "flak tower" standing in my yard, but their concerns were allayed when I faced the entire structure with flagstone that more or less matches our house, down to the "mortarless limestone" construction, which essentially means mortar on the back of the stone, with no grout filling the gaps. As a cool side note, it turns out that the flagstone has many fossil fish vertebrae and scales throughout. I'm not sure of the age or provenance of the stone, so I guess that adds a measure of mystique. What I do know is the provenance of the ammonites, and the buddies I was with when I found them on various trips. A couple of these guys are Forum members, so this thing now stands monument to both my wife's design vision, and also to various friendships. There are ammonites on all 4 sides, 10 in all, including Mortoniceras equidistans from the Fort Worth Fm, Eopachydiscus marcianus from the Duck Creek Fm, and Morts from the Duck Creek. One Eo even has a small Macraster washitae tucked into the aperture. Anyway, I drilled several drain holes into the base of both side planters, so now we can fill them with gravel and potting soil for my wife's choice of xeriscapic flora. We'd better get some good mail going forward!

Hello all, I think this question has been asked a lot here but It is still not 100% clear for me how to stabilise, glue and prep fossils. I've found some beautifel ammonites, a reptile tooth, trilobites... But every time I try to prep one it turns into a disaster after a couple of minutes. I have an air scribe and a lot of hand tools , but I am afraid of using them again since all of my tries turned out in the destruction of the fossil. Could someone give me hints on this? Greetings Thijs

I went fossil hunting in Lyme Regis for the first time in my life. I cracked open a nodule and found this ammonite "fossil". When I tried to brush the fossil area with a plastic brush is seemed to scratch away the fossil as well. The detail has disappeared. Is this just a poorly preserved fossil? If it is a proper fossil... what can I use as hand tools to release it? I don't want to invest in a dremel tool, and don't mind hard graft with hand tools if it's an option. The rock is super soft and easy to remove. I looked online and saw something about freezing and then running it under hot water as an option. Thanks in advance for any help! -Justin-

I bought this ammonite online, found in the gault clay of Folkestone, Kent, and it has some unusual markings on it. I can't tell if they're from before or after death or if they might be bite marks. There is what looks like a pyrite deposit in the dent and I was wondering if anyone could tell me more! Below are some pictures.

Finds have been really low recently because of all the good weather and people visiting beach more? or i just suck! I found this today near Whitby. Is it a Peronoceras?

Yesterday my girlfriend and I made a fieldtrip to the Northern French coast. The tides were ideal to search for the whole day in the late cretaceous chalk deposits of Cap Blanc Nez. The start was a bit slow, not a lot of fossils to be seen, but when going further up the beach the first ammonites started to apear. the result of the day where a few decent ammonites ( schloenbachia varians and Mantelliceras sp. ), a few shark teeth: Natalie found most of them and she found a spectacular cowshark teeth, the first one I ever saw from there. My find of the day was a small but complete Cymatoceras ( Nautilus )

Well, I finally decided to see if I could get a Certificate of Disposition for an ammonite partial found along the Bow River a few months ago. It took about 5 weeks but I received it today. At least I know I can obtain ownership for one of these babies. Now I have to decide if I want to sell this fella. Need to put some Opticon on it to spruce it up a bit.

Hello! I went fossil hunting at our local fossil/mineral/curio emporium. (Which I am SO lucky to live near!!!) I got several nice fossils!!! This Ammonite from Madagascar... I am thinking Perisphinctes - do you concur?
