Hi there guys. I received this piece with almost no information and I was hoping someone could help me ID it. It was supposedly bought in Kircheim, Germany. But it kinda reminds me of Perisphinctes... Would that be right? The plate is about 14 cm x 12 cm.

Hello, I almost die, when I was extracting this ammonite from wall of abandoned limestone quarry. So, that's my very first stone preparation, of 200 mm (7,8") ammonite (Perisphinctes), which I found near my hometown - Kraków, Poland. OK, I know, it's not so big, but the largest I have ever found. As You can see I got carried away, so it's half natural specimen, and half carving. Preparation I done with Dremel Engraver and some chisels I made from old files. I enjoyed it well

I recently bought these two ammonites from a seller who listed them as Kosmoceras sp from Khakassia, Russia, Jurassic period. Based on shape and size, I think these are likely the same species, but the white one has had more shell material removed; what's remaining looks super chalky with a lot of calcium in it. The more intact fossil has curvy ribbing and a slightly braided look to the keel, which has a distinct bevel. I haven't ever seen a Kosmoceras that looks like this - my other Kosmoceras specimens are pyritized fossils from near the Volga River and look much spinier. Can anyone confirm the ID or suggest a different one? Thank you!

I picked up this stone on the beach at Rhyl (North Wales). It looks like it might have at least one ammonite inside it. I was going to wallop it with the hammer, but then thought I might do some damage to what could be potentially a nice set of fossils. Each successive face is what was facing the ruler in the previous image, the last two being the "ends". Any suggestions, advice or ideas as to the best way forward would be appreciated. Thanks.

I spent most of Friday at a local creek with expert friend.... We found some nice things. I got an intact goblin shark tooth about 2.4" long, and some fossil turtle bone. My kids had a great time sieving in the stream. Ammonite impressions in the mud are common; I wanted to to share the largest one I saw, as well as my largest goblin shark find. We saw some good wildlife; the kids caught a garter snake. My daughter saw a mysterious creature that jumped into the water. I took some pictures of the footprints.... a mink maybe? What do you think?

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.

From the album: Cartier's favoroite fossils

I recently bought some small hematized goniatites from Morocco. They are each under 25mm and fully hematized. The two on the right look to be the same species, while the left specimen is wider in girth and has simpler sutures. They are probably too worn to have distinctive keels, but I've posted a photo of the keels anyway. Any thoughts on identification? I wasn't able to find a good source online for identifying goniatites to family or genus. Thank you for your help!

Today i caught on my camera a lovely dactylioceras nodule opening. Hope you enjoy, it's quite satisfying opening them but they don't always open like this. Probably one or two in 10.

From the album: North Sulphur River Texas
-
I decided on a whim to go fossil hunting yesterday. I took off on the 2 hr drive to get to my favorite area the North Sulphur River Texas. I jumped off in three creeks to see footprints everywhere. I decided to go try a creek I spotted a few years ago but never tried. It paid off. I found my first NSR echinoid after 4yrs of heavy hunting. Echinoids are quite rare at NSR. I also found a really cool Pachydiscus ammonite with an Inoceramid on it. I think I"ll try that creek again in the future.

Hello all, Currently digging through boxes I haven't looked through for several years and came across these two ammonites. I thought they were Kosmoceras grossourvrei but they seem to be too coarsely ribbed, Kosmoceras pollucinum maybe? Any help or advice with this would be greatly appreciated. Found in the Lower Oxford Clay of Kings dyke, Cambridgeshire. Callovian stage. Cheers, Jacob.

Great day today. Ended up getting a greenops some eldredgeops rollers some really nice brachiopods and even some carbonized wood. What was really awesome is I ended up finding 4 large ammonites out of the Wanakah shale which was strange. But hey I’m not complaining.

Hello all, This post is about two months before I can report any field experience but instead is a request for some more specific direction for ammonite hunting N of Kremmling, Colorado. I know we can not collect in the Ammonite Cretaceous Study Area, but I know, from the forum, that there are places outside the study area available for collecting. I have the Steamboat Springs BLM map, the Wolford Mountain Travel Management map, the Kremmling BLM field office map to the study area and have traced the route on Google earth to what I think is the study area. It is off dirt road route 26 to the left several miles in off Rt 40. I think the GPS coordinates for what looks like a parking area outside a gated entrance are 40 13 51 N, 106 23 55 W. Assuming this is correct, can someone who has had collecting experience in the area direct me to a potentially fruitful are where I can hopefully find ammonites? Any help will be much appreciated. Thanks. Tom

Went to an estate sale today to scope out a Paradoxoides gracilis that a friend spotted. Ended up being gone before I got there, which is for the best because after seeing the photos I wasn't sure how I was going to negotiate given the fact that it was a fake. (I still wanted it for cheap though, lol.) That being said, I did grab a few small fossils that they had for sale. They wanted 8$ a piece, but since they had an $8 price tag on a horn coral, I figured that 10$ for the whole pile was a better price. There are a few items here that I don't know so I am hoping that someone might recognize them or where they might've come from. As the owner was deceased, I could not get any information other than the fact that the previous owner traveled the world. First up: I don't know what this is. The texture and shape definitely says "fossil", the cross-section says "nothing". I don't know what it is or where it's from.

Hi, I found these ammonite specimens in the Oxfordian Ammonitico Rosso facies from the Baleriac Islands, Spain. I know that the preservation state is quite poor but I would like to get some help identifyng the genus and species. I am not familiar with ammonite description but here you have a very basic description of what I see: Specimen 1: No ribs, oxycone/discocone, involut, carinate? Specimen 2 (Taramelliceras sp?): two pair of ribs (primary and secondary), oxycone/discocone, involut Specimen 3: No ribs, discocone, carinate? Specimen 1

Hi everyone, I am currently trying to identify my collection of Crioceras from the lower Hauterivian of South France (Drôme) . It turns out the process is quite difficult... thanks in advance for your help!

Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.

new cenomanian ammonite prepps and restauration
Manticocerasman posted a topic in Fossil Preparation
on the last fieldtrip from this saturday I got a new batch of ammonites to prepp: the first one was realy easy to prepp, it was a small but well preserved Schloenbachia varians. next up is a Mantelliceras, I broke it in 3 pieces when extracting it from the chalk. I let the specimen dry at home and glued the pieces back together, I then prepped the specimen. After this step I grinded the some matrix residue left from the matrix and mixed it with a little bit of water and PVA glue, I used this mixture to fill and restaur the gaps in the ammonite. once dry I gave the ammonite a Paraloid B72 treatment for consolidation. I'm very pleased with the results

30-03-2019 cretaceous fieldtrip in Northern France
Manticocerasman posted a topic in Fossil Hunting Trips
This saturday the tides were ideal for a whole day of prospection at the foot of the chalk cliffs near Calais. We got there early in the morning when the water was going away from the cliffs. At the parking we were greeted by a veteran collector from this location, he took us along to the northern part of the site in search of big Turonian ammonites. A first for us since we've only collected more to the south in the cenomanian deposits. With his help we did find a couple of ammonites including a big specimen. around 1pm after lunch we parted ways and we went to the southern part of the site in search of cenomanian fossils, most of the beach was covered in sand, making it harder to find some decent boulders on the beach to break open. but the usual Schloenbachia and Mantelliceras ammonites did show up. we ended the day with dinner in a local tavern before heading back home whit a new load of fossils to clean and prepp. A Lewisceras Ammonite: A large Ammonite, I still have to prepp and Id it propperly: the extraction of the large ammonite: A nice find from Natalie: under the sand on the beach Albian deposits are present, but not visible, from time to time som fossils from those banks are washed out deeper in the sea and washed ashore. She found a nice Hoplites ammonite lying around on the beach: more pictures of the area: Schloenbachia varians: Mantelliceras specimens in situ: part of the fossils that made it back home: Pictures of prepped specimens will follow later

I just wanted to show off the beautiful colors on my Cleoniceras ammonite, unpolished! Unfortunately I don’t know the origin country of this ammonite because I bought it from the Lizzadro Museum in Elmhurst, IL.

Hi, I bought this ammonite at least 10 years ago and have completely forgot about it since then. It is rough on one side and cut and polished along the mid-line of the shell revealing the interior. I'm certain it is an ammonoid (vs a nautiloid) due to S shaped suture lines and outward curving septa. What I can't figure out is genus and locality of this ammonite. I think it's fair to say this is a mass produced ammonite from madagascar or morocco but I can't seem to find much on the marker currently to draw an association. I've attached some pics.. thanks for your help!

Hi, I will like to seek advise regard this ammoniteis it fake. As the shape and structure is something I never come across. I do not have any information where the ammonite was it found, so I post it here and hope someone ever come across it and can advise.

I found this ammonite recently in hard, microcrystalline Eagle Ford flagstone. Guessing it is Acanthoceras +/-, preserved as a calcite steinkern. I’m not sure how readily the matrix would release from the fossil, but I’m guessing it is not too eager. If anyone has experience prepping this hard stuff, I’m open to suggestions. Otherwise I’ll just cut the rock down to a small tile and leave the fossil as-is. @Ptychodus04
