  1. Turitella and other shells id

    Hi folks, what do I have here? The label says ‘Turitella Essonne France 45 million years old’ I guess Essone is a typo and should be Essonne? Cube is 1cm3 @fifbrindacier @Coco @maxfossils
  2. Gastropod Experts?

    I found this gastropod imprint a couple weeks ago in Tertiary sediment (geologic maps) I found this gastropod online (Falsifusus ludovicianus) which lived during the same time period and has similar ridges and those tiny crown marking near the top. Let me know if this seems reasonable (I put the pictures of the gastropod I found online in the comments below.)
  3. A Few Unknowns

    A friend of mine who runs a rock shop acquired a large batch of fossils and other items, and asked if I could help ID them. I've been able to identify most of them, but there are a few I'm unsure about. At least one of them seems to be a non-fossil geologic item. Some of these were acquired without provenance details. I'm sure my friend would be content to have it down to the genus level, if possible.
  4. ID for gastropod.

    I cannot take anymore photos as this was not my photo but if anyone could identify these. They are around 15 - 20 million years old. Eocene period found in western washington
  5. Indet. Gastropods - Les Roches Noires

    From the album Best of 2018 finds - a year in review

    2 nice gastropods internal molds from "les roches noires" (Oxfordian)
  6. Ammonite-gastropod

    Hi everybody. I made an exchange with someone who gave me that ammono-gastero fossil. The ammonite has 7 centimeters of circumference and the gasteropod 2,5 centimeters. All the information i have is that they must be from the Callovian stage, and i think they are from Britanny, in the North-West of France.
  7. Bourguetia Sp - Les Vaches Noires

    From the album Best of 2018 finds - a year in review

    Bourguetia Sp : a gastropod from "les Vaches Noires" cliffs' oxfordian ooltih.
  8. Okay, I know these two pics will look pretty indeterminate, but would anyone be able to get me past cephalopod and gastropod and into an area where I can research and expand my knowledge. Both these were found in the Mississippian, Lake Valley Formation, Andrecito Member (early Osagean). Clear association to Zoophycos with which these were found.
  9. Hi everyone, My last hunt of 2018 was incredible. And quite surprising too! For Xmas, we went to Middelburg in Zeeland to visit my mother's family, which is always a huge load of fun for me because I get to hang out with all my cousins, that I don't see very often. Anyways, one of the days, they all wanted to do a big walk on one of the beaches. At first they wanted to go to Dishoek, but I managed to convince them to go to the Banjaard instead. Once arrived, we split into 2 groups: one was my mother, my eldest cousin (18), my 2nd-youngest cousin (6), and I. All the rest went to the other group. The other group just walked, but our little group did something much more interesting... You guessed it: fossil hunting! As soon as we got onto the beach, we almost immediately found our first fish vertebra, but after that we seemed to have hit a small dry spell for nothing really worthy was being found. A few common fossil bivalves here and there, but nothing more. For my two cousins, it was their first time fossil hunting, and we had to give them a few examples to show them what to look for. I told them to focus on the fish vertebrae, because these were the easiest to recognize. The smaller one also did a lot of shell-hunting on her own, always picking up the most colorful ones and saying this one was Mama shell, this one Papa shell, this one Sister, etc until she made one giant family of orange shells Then after about an hour or two of hunting with rather little success, we finally hit these little shell banks on the beach. And there, BINGO! Gastropod after gastropod, we couldn't stop finding an incredible amount of them. On the Dutch shores, fossil (and modern too) gastropods are generally much less common than fossil bivalves. So the amount we found here was very surprising!
  10. My finds from North Sulphur River near Ladonia on Saturday, December 22. The weather was great, the water was low and competition was moderate. Pleasant surprise finding an arrowhead. The little vert and the plate-like bone were both found near the Hwy 34 bridge.
  11. Hi. Here are some shells from our desert property. Also some burrows/worm tubes I think? There's a tiny shell inside one of the holes (pictured). .
  12. Albian gastropods ID Help

    Hello! I hope to get help from experts to ID some Albian gastropods. All are from the Zirc Limestone formation, Hungary, Bakony Mts. All are stone moulds, with some shell fragments. I know, there is little hope to ID the species, but I love to know the genuses at least! The bigger boxes are 6x6cm, the smaller boxes 4x4cm. I can upload separate photos if needed. Please do not mind the last 2 boxes! (Not gastropods) With Kind Regards.
  13. I found this last weekend in the Grayson Formation in Tarrant county, Texas. I have never found a Cretaceous gastropod that was so squatty. Most that I find are elongated to some degree or another, but there is no elongation to this one. This was posterior end down in the creek bed embedded in the limestone. I popped it out, but I guess part of it remained in the limestone. I tried to prep the matrix off, but I can’t tell where the matrix ends and the shell begins since it appears to be a steinkern. There is no ornamentation on it at all. It is about 36 mm at the widest whole part, but looks like it was at least 50 mm wide at one time. I can’t tell how wide the aperture or last whorl was. The total height of the gastropod is 20 mm tall. The overall shape is lenticular. I don’t think there are many lenticular gastropods in the book I have. I couldn’t find one that matched it. Top view (which is actually the posterior end of the shell) Side view Bottom view (which I believe is the anterior end of it) Any help at all would be appreciated.
  14. Simple Mid-Devonian ID?

    Took advantage of a break from the early wintry weather to go play in my fossil pit out back (London, Ontario), and came upon this. I'm sure this will be a cinch to identify, but i'm drawing a blank. It has ribbing reminiscent of an ammonite, but this was found in the Dundee Fm, Mid-Devonian, so too old for that. Ammonoids from around these parts don't tend to have ribbing like this, nor the appearance of nodes. I was thinking some kind of coiling gastropod. Too large and flat to be a Paleozygopleurid. If it is a gastro, I know how tough they can be to identify from a steinkern, but I thought I'd give it a go. As I'm one of the few on here who have access to Dundee Fm deposits, perhaps it is reminiscent to a similar Devonian formation where one of you collects. Does this seem familiar to anyone? Sadly, try as I might, I couldn't locate any other pieces from this rock, so this is all I have to go on.
  15. This is a continuation of my last post with @UtahFossilHunter going back to the island last minute before the snow flies. This time we tried another outcrop of the Undifferentiated Cambrian (now determined to be the Chisholm Formation) on the search for fossils. Link to Part 1  Here is the map on my last post.  This is the Chisholm Formation at the foot of the mountain.  We went up farther on the mountain and found a contact zone. Being a large dipping anticline going down the slope at an angle, the rock layers get older on the bottom then the top. Other places on the island the rock layers are rotated sideways so we kept going right and slightly down more.  We kept going up and we found some Bonneville gravel.  Further along we found lots of a good structural rock with en echelon fractures from nearby faults. But no fossils. We decided to check a few other rock layers again just in case. The Ordovician Garden City Formation had absolutely nothing. So we went back down and drove to another place where the Silurian Laketown Dolomite outcrops so we hike up and.....  We found our first Silurian fossil! We didn't expect anything to be in this formation. Unlucky for us, it was on a boulder so we thought we had to take out a chunk of it. UtahFossilHunter and I had forgot our chisels but we had our hammers. So for ten minutes we kept trying to break off the chunk it was sitting in. You can see in the pictures the fossil was on a ledge. The bedding layer below was a large chert nodule layer so every time we hit it you could hear little shards zooming by like ricocheted bullets. After that ten minutes while watching the snow clouds make their way across the Utah-Nevada border, we decided to take a risk and try popping the fossil out just underneath the shell. That risk payed off and it came out whole. The lesson here is if you know you might be looking in hard rock layers don't forget your chisels. 
  16. What was this doing in Maryland?

    I’m guessing weathered conch, but VERY bizarre to be seen in Maryland...
  17. Any gastropod expert here?

    I have found a lot of gastropods but I want to know the sp'. And if you can put a link to a identification sorce. Here are some of them:
  18. Hey folks, I was wondering how you guys would approach something like this (or if samples like this are even worth your time!) There's so much going on I'm a little confused as to how and where to start. would you remove the gastropods individually, break the rock apart, sacrifice the broken ones in the search for more complete specimens, leave it as is? I went through the pinned messages and learned a lot, but was curious if anyone's come across similar types of rock and could give some insight. My goal is to hopefully find and extract some of the more complete specimens, and maybe discover some trilobites along the way! The plan was to chisel out as many surface fossils as possible, then strike the rocks with a sledge hammer to break up the pieces, give them a good hard scrubbing, then use my steel picks and chisels to poke around further however the resources provided to me by @FossilDAWG and @Kane (thanks again by the way!) described a number of rare, some now lost, trilobite specices from the same formation found in similar contexts alongside Ceratopea Canadensis, so maybe a lighter touch might be in order? I'm still a little scarred from the time I put a pickaxe right through an almost complete piece of 1st century terra sigillata once upon a dig </3 I'll definitely be looking into air pens/compressors (looking at you ME-9100) as well, but on my pay that's one of those 'somewhere down the line' sorts of purchases. If those are definitely the way to go however, I can always shelve these for that later day...they've been sitting around in a forest for this long, another few months wont hurt! I did notice while cleaning the sample below that there appeared to be two separate matrices, a softer one which I assume was the sand/silt and then the hard dark rock underneath. I've got a much bigger slab with a lot more going on, but I grabbed this little one to practice and learn on! My first target is that crystallized one which is slightly exposed on the top (bottom center of the picture on the right) followed by whatever that is beside it and that mussel looking fellow.
  19. Hi guys! This is a continuation of a previous post focusing just on the sponges. These fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. Because these fossils are in the park, no collecting was allowed, and I can't provide additional images. Any confirmations about the identification or suggestions about a more specific identification are welcome. This trilobite is the only fossil out of these images that was actually found in Carlsbad Caverns, right behind the elevator. Can I get more specific on an ID? Cross section of rugose coral? Sponge? Bryozoan. Acanthocladia? Bryozoan? Crinoid.
  20. Hi everyone, This little guy comes from Carniol, France. It is from the "Gargasian", Aptian, Cretaceous. Surprisingly, unlike most other finds (so everything except for belemnites), this one doesn't seem pyritized... Anyways. It's pretty flat (because of geological processes flattening it; my gut feeling says that naturally it is meant to be much rounder). Now I'm really not sure if this is a weird heteromorph ammonite or a weird gastropod. I would guess that it is a gastropod simply because they are much more common, but it just looks so weird that I'm stumped. Hopefully you guys can solve my little mystery! If better pictures are needed, which will probably be the case, I will make them. Thanks in advance, Max
  21. So a few more gastropod pics

    So I ran across 2 more gastropods from Sarasota Florida APAC that have been hiding in the garage--well maybe not hiding--just buried in the junk. Doesnt seem to be something common unless I have some tiny ones somewhere. Probably Tamiami Fm. Plio-Pleistocene. Thought they were the same initially and I had lumped them together. But now I see the one on the right has a depressed end. So maybe a Prunum sp. and a Bullata sp? that would be cool. Thanks for the looks and any feedback. Regards, Chris
  22. Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
  23. Fossils in marble

    Hello! Can you please help me in identifying the marked fossils and give an estimation on their age? The fossils are found in my office's marble wall and floor coverings. There are many more fossils all over the building. The size of them are generally between 5 and 15cm. Thank you in advance!
  24. Florida Invertebrate trace?

    Hoping someone easily recognizes these and its an easy answer...my initial searches have been fruitless... So I was supposed to be looking for more Florida coprolites in the garage piles of fossils and got sidetracked looking as this large Turbinella columella and just noticed these tan circular markings on it and wanted to know if they were traces of serpulids? Probably Pliocene Tamiami formation, Sarasota County, Florida. Whats fascinating to me is their spiral?/concentric, ornamented/segmented? shape which appears to actually be etched into the gastropod shell itself. Almost look like cross sections of forams. I've scraped a number of the small white serpulid tubes off thinking I'd see a similar pattern but there is no marking beneath them--its perfectly smooth. If it is a tube, I wasnt aware that they could actually score the surface of the gastropod shell--seems pretty neat if thats what going on but maybe its something entirely different. The gastropod, aside from being badly damaged has sponge borings, barnacle and coral encrustration, and serpulid tubes. Most of the circular traces are around 1mm in diameter and a few push the 2 or 3mm size. Thanks for the help! Regards, Chris
  25. Gastropod ID Please.

    Hi Folks, I found this piece a few years ago. There is one problem. I can't remember if this was found at Venice Beach Florida, or Assateage Island Maryland. Anyways there are these reddish/orange gastropods stuck in the matrix. Any of you shell experts know what I got? Thanks in advance. Dave
