In the summer of 2020 jpc and I had planned to get together in Eastern Wyoming to collect. That trip was unfortunately aborted by the coronavirus outbreak that year. This year, that conversation resumed and a new plan for a three day excursion in June emerged. I decided to make it a two week long car trip, driving all the way from New York, a longer car trip than any I've made in the past 25 years. That would afford me the opportunity to stop at some other sites on the way there and back, plus see some family. Another big reason for driving was an opportunity to visit and collect at the Big Cedar Ridge Cretaceous plant site. Having the car would afford me the opportunity to bring the necessary tools and be able to transport the fragile specimens safely. The rising price of gasoline certainly had an impact, and my plan was to cut costs as much as possible wherever I could. Part of that plan was camping 10 nights I departed the suburbs of New York City on Saturday, June 11th. That evening I arrived at Sturgis, MI, just off interstate 80. Spent the night in a motel and headed off the next day, driving through the heart of Chicago enshrouded in mist. It was my very first time driving through that city. I headed north and in the middle of the day arrived at my cousin's place in Madison, WI. He had moved there from Manhattan five years ago to teach music at the University of Wisconsin. This was my first time visiting him there, my first time in Wisconsin, actually. He took me on a lovely tour of the school and the town. I spent the night and was on my way again just before noon the next day. It rained off and on as I drove through Western Wisconsin and crossed the Mississippi into Dubuque, Iowa. From there it was a short drive to my first fossil stop- at Graf. This Upper Ordovician site in Maquoketa Formation is famous for its nautiloid death assemblage. I have found quite a few nautiloids over the course of my collecting career, but I've never encountered a site where they are thoroughly dominant. There was a layer of limestone, a few feet thick that was in many places just packed with their shells.

Hello, I have recently found some gastropods in a village of Teruel, East of Spain. They are from Albian Cretaceous. Visiting the local museum has not solved my doubts about their identification, they had some gastropods as mine, but, to my unexperienced eyes, there were identical specimens under different labels: Paraglauconia picteti, Cardium Voltzi, Glauconia lujani, Orthostoma verneuilli, Turritella vidalina and Cassiope luxani. I am sure it is not Cardium Voltzi, as it is a bivalve, I have doubts about Glauconia lujani and Cassiope luxani being synonims, and I haven´t been able to find anything about Turritella vidalina or Orthostoma verneuili. I have separated them in 4 groups according to their ornamentation, I hope someone can identify them: Ruler is in centimetres and inches. 1st group, two rows of lumps per whorl: From left to right, 1A, 5A, 2C. 2nd group, two spiral ribs per whorl: 8B. 3rd group, a spiral rib and a row of lumps per whorl: From left to right, 4D, 3B, 4C. 4th group, smooth surface: From left to right, 5D, 6D, 8D. Thanks in advance for your help!

My parents were gifted this piece years ago and now that is has passed to me, I was curious to find out details. I see gastropods and a shell. The piece is almost a foot long with a bright green felt attachment on the back. Unsure if they received it in Australia or in America. Any other information or feedback is greatly appreciated.

Hello again, I found these tiny specimens today, and I'm not quite sure what they are. If I had to guess, I'd say the spiral shelled creature is Amphiscapha and the more clamish one looks a bit like Kozlowskia without the little side wings. No idea what the last one is. As always, all help is greatly appreciated. Also, sorry about the bad pics, these are quite small specimens.

They are from Isla Margarita, Venezuela. Anyone know what these are?

These came with only vague data: Sahara Desert, Morocco. They are apparently three species of Cerithioidea. A similarly preserved gastropod (a stromboid) with a carnelian shell that I came across had good data: (late Cretaceous (Maastrichtian), western Sahara Desert, Dakhia Region, Assa, Morrocco). They have fine white silica sand with silica cement infill and attached, making cleaning very difficult. Any help would be appreciated.

I found several kinds of gastropods and two other uknown fossiles in the Kalvsjøen formation, late Ordovivcian at Hadeland in the Oslo field, which I like to share. The limestones in this formation are called 'the Gastropod limestones'. Can anyone please help ID some of these fossils. I guess some of the gastropods cannot be ID-ed, but I hope some of them can be at some level and the other unknown animals. Any help are appreciated. The first rock (the first 3 pictures) has one strange fossile (to the left) and several small gastropods, some very small, which I could only see by taking several pictures from different angles and by using different light sources: Enlarged left side: Picture 3, the right side enlarged: The next, rock no. 2, has a nice shape of the cross-section of a gastropod with 5 levels or spirals: It also has a strange very small fossil, near my finger. Picture 4 Pict. 5 Pic. 6-8, enlaged small fossile: Rock 3, picture 9, another gastropod in cross section, size is about 2 cm broad: Rock 4-5, picture 10-11, two very small and nice gastropods, which I did see only after I enlaged a picture I took of the rock with a microscope:

I was so disapointed with the last concretion I started that I put it aside and started working on making some short fossil videos to put onto you tube. Here is one of many. My plan is to publish 2 each week. Enjoy RB https://youtu.be/pcTBB-QRKGw

Since we both had the day off, my daughter and I spent a couple of hours at the Deer Lake site (Schuylkill County PA). It was a beautiful sunny day in the mid 50s! A good start to this years fossiling adventures...

I got the chance to go to the Oxford Clay twice over the last few days. I'm always looking for echinoderms at this site, and I prefer this one in winter when the vegetation has died back and I can spot lots of small, delicate detail. These are some if my favourite finds from the last few days.

Hello everyone. I offer interesting gastropods from Neogene - perhaps someone will be interested I have a lot of them. They are found in the Khmelnitsky region of Ukraine; the exact age could not be determined. I'm interested in everything - I invite you to private messages Have a nice day

Hi ! So I went on a walk in some marls in Lozère, France. Usually, I find some amonites and belemnites but this time I decided to change from my usual spot and searched around. I found an isolated marl which is a couple of kilometers away from the main marls which are known to be from the Toarcian. In the whole region (région des grands causses), marls can be either from Toarcian or Pliensbachian according to french wikipedia (https://fr.wikipedia.org/wiki/Marne_(géologie) ). Anyway in this new marl, I didn't find the same fossils as usual, at all. I found mainly gastropods, very small bivalves as well as some rare cases of amonites (which are abundant on the contrary on the other spot). So I was wondering what they were. I believe there are at least two different species in my findings : those on the upper lines look like some pictures of Amphitrochus pictures I found on this forum and on the net. On the second line are what I believe is a second species I didn't really manage to find similar thing on this forum. Under it I put the best looking very small bivalve I found in the very same marl. Do you know what could those be ? I hope it interests you ! Alice

Gastropods with calcite crystals from Oxfordian stage (163,5 mln years)
Svetlana posted a topic in Member-to-Member Fossil Trades
Hello everyone. I offer interesting gastropods with calcite crystals - perhaps someone will be interested I have a lot of them. Pseudomorphoses of calcite after gastropod shells of the genus Nerinea from Upper Jurassic limestones of the Oxfordian stage (Izyum Formation J2-3iz); 163,5 mln years. Ukraine, Donetsk region. I'm interested in everything - I invite you to private messages Have a nice day VID_20220122_135535.mp4 VID_20220122_135732.mp4

I believe I got the material from someone on here years ago and I get a chance to go through some from time to time. This is Alafia River stuff from Lithia Florida. It had a note of Oligocene/Miocene for age. One of them is kind of hard to see but right beside the other and I suspect these are internal molds in a piece of coprolite.

Hello and happy New Year! I have visited this region a couple of times, earliest being around 2000 and last time just a few days before the NY Eve. My first visit was limited in Chaeronea, in order to visit the Marble Lion that was erected in honour of the fallen soldiers of Theba, who fought against Philip, father of Alexander the Great. The battle took place in 338BC, technically was a civil war between the city state of Athens and Macedonia. (The Lion) Following the road South of the lion, I found my first rudist on a dirt road. All I can say is that the site is Santonian. Years later, December of 2019 or 2nd of January 2020, I visited the mountain of Ptoo at the locality Marmeika. This is an abandoned nickel mine, more precisely, a pit. Middle Turonian possibly up to Coniacian This is an amazing outcrop for rudist lovers, because you can observe huge colonies in life form. I really regret it I did not take pictures last time.. Moreover, it is the place with the most diversified fauna. I will start with the finds of the first time. Nerinea sp vertical cut and steinker. Very typical find, usually away from the rudist zone. Radiolites sauvagesi, I think. Abundant in the lower greyish limestones. Finds of my last visit. A quite large sponge (Demospongiae?) which is completely silicified. I am not able to narrow down its species. Close-up showing its stracture An amazing Actaeonella sp, which has all of its shell, yet one end missing. My top find I think. The same Actaeonella next to a cross section of another Actaeonella. A nice gastropod that looks like Ampullina sp but did not find a reference. More Nerinea sp One more Nerinea sp as found And after 1h of cleaning. The limestone is very soft and easy to remove. Two interesting rudists. The left one must be Radiolites mamillaris. The one on the right side, no idea! Rudists collected in the area during my last trip to Greece, December 2021. Still in boxes in my car. Aghia Varvara section: The scientific research leads you at a small hill, near a chapel. Although it is described as rich in gastropods, the area has mostly badly preserved specimens and some fractured rudists. The most interesting find from this section, is a matrix free cross section of a rudist, replaced by calcite. It is just a slice. 1.5-2Kms SSW of the section mentioned above, we found another layer of the same formation which gave some nice fossils. Neoptyxis incavata or Neoptyxis symeonidisi, as per the references. Can't tell which one. The gastropod on right side, no idea. One Neoptyxis sp in situ. The layer that was found was tertiary so it must have been redeposited. Rudists are very underrated fossils. However, if exhibited with other species of the Cretaceous sea, will create a very artistic illustration of a reef. Maybe there is someone who might be able to help a little with identification @FranzBernhard Hope you enjoyed! References: Cretaceous Rudists of Boeotia by Thomas Steuber [1999]

The lower Hunter Valley is underlain predominantly by Permian strata, and encompasses the region around Newcastle, NSW, Australia. It is here that a diverse fossil macrofauna can be found at a disused quarry standing on private property. Mulbring quarry is characterised by excellent exposure of the Permian strata with macrofauna dominated by abundant bryozoans and brachiopods, associated with bivalves, gastropods, and echinoderms. With the weather typically windy this time of year it was no surprise when we hit the black top with a strong westerly wind blowing, fortunately the sun was shinning. The plan was for my family to meet up with my retired geology teacher friend and his wife at the gate to the property. Two weeks earlier I received access permission from the property owner and we met my friends at the gate and headed up the track. Stepping out of the car upon arrival at the quarry our excitement peaked quickly with fossils bearing rock lying all around us. It didn't take long for my friend Col to find a lovely Bryozoan, my find with a specimen of fossil debris, including fragmented gastropods, isolated echinoderm ossicles and small brachiopods (pictured Mulbring 001) followed quickly after. We spent the next couple of hours fossicking around, then stopped for a well prepared picnic in the Australian bush. A few more hours of fossicking revealed the beautiful Bryozoan also pictured (Mulbring 002). These fossil beds also contain a particularly high abundance of fenestellid bryozoans and brachiopods (spiriferides and productoids), with bivalve molluscs the next most abundant. Minor groups include gastropods, rostroconchs, corals, trilobites and several types of echinoderms. Sadly, the trilobites and intact echinoderms evaded our gaze. I've already began my visit to one of the State's Jurassic sites early next year! Cheers Adelotus

My wife and I are up in Northern Vermont for the Thanksgiving holiday and were able to take advantage of a beautiful day yesterday by going for a walk in some woods and fields along Lake Champlain. While exploring the shoreline, we came across this rock wall and my wife spotted what looked like a fossil shell. Lo-and-behold, the wall was full of fossils--primarily gastropods I believe. We're not sure where these rocks came from, but the rocks along the lake are Ordivician in age and there's a good chance these came from a similarly-aged rock quarry in the region. Here are some of our finds, which we were able to enjoy in place: And some views of the Green Mountains and Adirondack Mountains on our way back:

Help with some micro-gastropods from the Middle Jurassic of the UK
IsaacTheFossilMan posted a topic in Fossil ID
Hey all! Today I bring you some teeny tiny gastropods! All Inferior Oolite Group, Cotswolds UK. Every formation. There are a few different species that I have described here: Species A: "helter-skelter". A very very loose spiral, resembling a helter skelter... Species B: very neat loose spiraled. Species C: very tight spiral, very common Species D: fascinatingly bumpy textured spiral. Reminds me of a wallpaper! Measurements in cm. Isaac
