Fossil Forum, I have recently uncovered the external mold of a gastropod. I am thinking that it is Platyschisma helicites, but am unsure. The main problem is that I am unaware of the formation it is from. I found it right next to an outcrop of the Leighton Formation, but the fauna and the matrix does not match it. It might be from the Edmunds Formation, but I am unsure of this too. Either way, they are both Silurian. Any help on its ID would be appreciated. Here are some pictures of it:

There is so much going on on this rock not sure I captured it all. Found in park east of DFW airport, North Texas Eagle Ford. Most interesting is the long object running down center of rock, almost the whole length. Have not been able to find anything similar. Not sure what else is there other than snails, ammonite, bacculites, maybe worms and tiny turritella looking gastropod? Appreciate any ID !

Despite the shortest and most mild winter I've experienced in North Dakota (getting out this early is rare) it still feels like it has been an eternity since I got out. Thankfully I finally got a hold of enough landowners to warrant a trip to the Fox Hills Formation and celebrate the spring weather. While most of the later sites I visited were a bust the first site of the morning was excellent and contained fauna not often found in the Fox Hills Formation in North Dakota. 3 new species for me in fact. This site represents a brackish transition area of the top of the Fox Hills Formation. A view from the collecting hills. Note the water bodies are still frozen. Some farmers were burning stubble in the distance. One of the more significant exposures. Compared to the other 2 outcrops on the hills this one was poorly fossiliferous. Anomia micronema and Crassostrea subtrigonalis (glabra) litter the surface of the worn outcrops. The bedrock was basically an oyster bed hash of graywacke sandstone. This oyster laden sandstone isn't unusual but you usually don't find the additional fauna (see below). In-situ Crassostrea in one of the unworn exposures. Some of the nicest specimens. Moving clockwise from upper right is Pachymelania wyomingensis, Pachymelania insculpta, Corbicula cytheriformis, Crassostrea subtrigonalis, and Anomia micronema. Pardon the bad picture and for our international friends the coin is about 1.9 cm. I took this picture for the landowner since he was interested and I included a scale he'd know. I was also too tired to retake it with my metric scales. I plan to take better ones later. Nice sculpture to the Anomia. Most were not so iron colored. There are some additional things in pieces of the sandstone I brought back. I have an idea what this is but want to prep it to see for sure. This is larger, about 5 cm across. On the way back to the main roads I found a farmer in the middle of nowhere with a sense of humor. I also collected a couple smaller concretions of the more typical ammonite Fox Hills concretions from another site. I'm not expecting much based on their size but if there is anything interesting post preparation I'll post those as well.

Having returned last week from a nice visit with my son in Florida, it was time to examine the fossils that I snuck home with. Eventually, I will make a trip report, but I need to identifying my unknowns first. So Here goes, and I might as well tag @MikeR right off the bat! The next unknown appears to be sponge like. In fact the largest one ACTUALLY FLOATS in water. So these are very light weight. I couldn't find sponges in the Tamiami, so maybe my formation is incorrect. The rubble that these came from contained much coral and large scallops. The next three are all on the same picture. The wind was howling and I had issues with these blowing away. So inbetween gusts, I took a quick group picture. These are TINY! These scallops have 17 to18 ribs I am guessing these are modern land snails but am not sure. The shell is VERY delicate. i Thanks for looking, Mike

My girlfriend, Valerie and I were visiting my aunt in West Palm Beach, Florida. She is 90 and lives in a senior residence. I wasn't planning to go fossil hunting or even thinking about fossils. However, on our last night there, we were walking in the neighborhood to burn off a few calories when I spotted a number of fossil shells in front of an apartment complex. We spent about half an hour searching the shells for complete ones in good condition- found over twenty species. Valerie got into it too and found some excellent specimens. After that we began spotting fossil shells everywhere. It's amazing how much you don't see unless you're really looking. Since this isn't our usual stomping ground- could use some ID help with these:

Fossil forum, Good morning. I have been looking for literature on the following for a while now, and have not been successful. I was wondering if anyone already had information on the following, or can direct me to a place where I can look for it myself. Brachiopods, specifically Lingulids (classification and identification) Salopina genus ( classification and identification), this genus was moved from Orthis, for further clarification Rhychonellida (classification and identification, at least to the genus level). Camarotoechia genus (classification and identification); Strophomena genus (classification and identification); Gastropods, specifically Platyceras (classification and identification) Bivalves, specifically Modiolopsis and related genera (classification and identification) Ptychopteria genus (also known as Actinopteria). I am also interested in the fauna of fossil formations in northeastern Maine, specifically the Edmunds, Eastport, and Leighton formations. Thanks in advance!

Greetings! I've been collecting marine fossils ever since I could remember. However, only recently have I started reading and researching about these fossils. I started researching for the correct rocks to break open in hope of finding new fossils (ammonites, fish fossils, etc..) instead of my usual findings (gastropods, clams, rarely urchins). I took some advice from you guys and began looking for a good book that might help on which rocks to look for (keepings in mind Lebanon is mostly early-middle cretaceous and Jurassic) I've used this map to find my way to Jurassic areas. a few days ago, I reached a Jurassic area and began my search for any fossils. Alas, my journey was not as easy and rewarding as I thought it would be. Thus, I came to the conclusion that I was not ready to start my search without some tutoring and learning. We're snowed in this week, I will use that time to begin my study. Meanwhile, please have a look at some specimens from my collection. I'm aware that my collection is considered common (VERY common, especially after seeing the amazing fossils on this forum! Haha!); however, I have no idea how old they are, if they're all early-middle cretaceous, or what they're called. Here are some of my specimens, gastropods and bivalves. the black looking clam to the right, was found in my recent journey to a Jurassic area. I broke open a yellow-brownish rock and to my surprise it had numerous fossils. I'm under the impression that the black color is the actual shell, in contrast to the other fossils in the picture which lack a shell (i think). In other news, i have a shell that i can't seem to identify. It looks like the upper half of some sort of clam (please excuse my simplified vocabulary i don't know what else to call it). its immensely layered and on the bottom side, it looks what appears to be the solidified insides of the creature (not sure!) Finally, i would like to know if this is an ammonite, its much different from the ones i see in pictures while surfing the net on how to find them. Thank you for this amazing community, I'm delighted to see people with such skill and dedication. I have much more content to post and learn about! Thank you. Regards, Karam

Short Icy Miocene Trip around St. Josef, Styria, Austria
FranzBernhard posted a topic in Fossil Hunting Trips
Icy? Well, compared to some areas in the US or Moscow, it had only a few degrees below zero (Celsius) last Sunday. The nights had about -10°C, the days about -2°C. This period lastet from last Friday to Monday. No snow at all and very, very dry air. The last two days we had about 0°C during the night and +10°C maximum during the day. Still very dry. So without any snow and clear, but "cold" weather, I checked out a few Miocene sites around St. Josef in western Styria, Austria. I have made a detailed report about the area more then a year ago here: Rocks and fossils were mostly firmly frozen to the ground, and in some places more than 10 cm long fibrous ice was growing from the ground, pushing up leaves, soil and in some places fossils. Sites looked mostly the same as during my last visit, except Höllerkogel-10. Here at Höllerkogel-10, the farmer had removed a little bit of material from the bank of the forestry road. The sites contains mainly Granulolabium snails, but also a variety of other molluscs (see topic above). A little bit surprising last Sunday were an echinoid mold and a leaf impression, both ready to be picked (see pics, fossils as found frozen to the ground ). Echinoids are known from this site, but I have not seen myself such a "big" leaf in this formation until know. First I thought that this leaf is a recent leaf, sticking to the rock. But it isn´t, its a fossil. The echinoids occur as molds in the upper part of the outcrop; the lower part contains quite well preserved shell fossils (gastropods and bivalves). Nearly everything was frozen to the ground, of course, and large blocks of fossiliferous sediment were frozen hard like concrete. Maybe I will visit the site again in the near future to pick through some of the fresh debris. The large blocks have probably disintegrated then. That´s all, thanks for looking! Franz Bernhard

Hello fellow fossil hunters! Ever since i was a kid, I would always find fossilized gastropod and clams. They are widely found in Lebanon and ever since I was a kid I collected them. However, through my interest in fossils, I learned that what I found was very common. So I started looking for new things. Although I'm still not an expert on which rocks to break open (I pretty much guess which rock to break), I seem to have found some luck. My collection is mainly composed of large gastropods(snail looking) and other types, bivalves, one amonite, and one urchin. The urchin is like my ultimate find. In Lebanon, fish fossils are widely available. I see them everywhere! (on the market). I have yet to learn where to and how to find them. My reason of joining is my hope of getting to know this field better. My fossil hunt is basically breaking every rock I suspect of having a fossil Haha! On the other hand, i enjoy farming, and I am biomedical engineer that loves to invent stuff! I also live in Orlando Florida, although I am not there at the moment. Lebanon is my birthplace and enjoy visiting frequently. It's been a trip looking at all the pictures of finds on this website and I'm glad there are other people who enjoy this. I'm always baffled by fossils, having a creature that once roamed earth almost a hundred million years ago in the palm of your hand. Ill be sure to upload pictures of my collection. Goodluck to you all!

Hi all, Last part of my finds of the year. In autumn, between lockdown 1 & and lockdown 2, we managed another 3 days hunts. First day was spent in our usual trilobites spot, which happened to be on the way to our main destination this time. You have already seen in my first part some of the trilos we did find on that day, which was a rather good one for me. Day two was spent in Nanteuil quarry not far from Niort. the quarry got mostly bajocian and aalenian. the aalenian is on the "ground of the quarry" and was mostly drown at that time of year. So Bajocian that was. An explosion had occured recently so we had quite some material to process. Most of the ammos there have no heart, which is quite frustrating, but from time to time, you can fine a pretty one. 2 finds on that day : Normannites sp ammonite A huge not yet determined nautiloid (not the usual cenoceras we find there) We kept going till 18h30 then it was time for a shower at the hotel and a meal at the restaurant. -
Hi Everyone. I found this gastropod at Whiskey Bridge, near Bryan, Texas two years ago which so far I've been unable to identify. Whiskey Bridge is a marine Eocene site, Crockett Formation, Stone City Member. The specimen is between a half and three quarters of an inch. Thanks. Any ideas would be appreciated.

A firend of me sent me this pic of cobble stone he picked up on the seashore. The only thing I could tell are the gastropods. What else are there? Possible ID and age?

Cold day in the desert but a ton of fun with some great finds! Thank you @PFOOLEY for the wisdom. These all were found in the Carlile formation in Sandoval County, New Mexico.

I have been working through a bag of matrix that I received from @sixgill pete from the Waccamaw Formation (Pleistocene) of North Carolina. Earlier I showed a couple of interesting bryozoans that I picked from the matrix (Waccamaw Bryozoan) and the first group of gastropods (Waccamaw Gastropods I). From the 1 quart bag of matrix, I pulled out over 60 different species of gastropods and am up to about 45 species of bivalves! This post represents the second group of gastropods that I have some identification questions about. Again, these are all very small, most are only a few mm's. I appreciate any input, thanks!! 1) The first one up may be the toughest, just because they are incomplete. I have tentatively called them Cerithiopsis bicolor based on Gardners 1948 work and Campbells 1993 publication on similar aged material from Virginia. As usual, I have tried to corroborate these ID's with other sources and tried to use the most up to date nomenclature based on what I find in WORMS, Fossilworks or The Neogene Atlas of Ancient Life websites. 2) Next is a really nice looking, but very small gastropod that I think may be Teinostoma carinatum based on Gardner, but T. lenticlare in Campbell also looks pretty similar. Of course, neither may be right!! This is one of three different species within the small Tornidae family that I found. 3) This one is also a very nice looking specimen but within several references I could not find a very good match. The best I could do was a species of Vexillum based on the general shape, ornamentation and columnar folds but the ones figured in both Ward and Blackwelder (1987) and Dall (1890) had differences from mine. 4) This pair may not even be the same thing as you can see there are slight differences in the ornamentation, but I have about a half dozen and they seem to al least fall into a pretty similar group. I have called these Chrysallida beaufortensis but am not at all confident in this especially since they my just be very young versions of something else. 5) This group is just part of well over a dozen that I found but can't put a good handle on. Perhaps some species of Pyrgiscus (which may now be Turbonilla)? Lea (1843) had a P. daedaleum which looked similar, but I was unable to find any reference to that species since that time. 6) And lastly, is a nice glossy but a bit chewed on specimen that I believe is a species of Turbonilla. T. delta from Campbell (1993) has a description that sounds pretty similar but the illustration in my pdf is poor so I'm not certain. OK, that is all. Again I appreciate anyone taking a look and if you have any ideas, I'm all ears! Maybe @MikeR or @Coco will have some more excellent insights this time around. Thanks again Mike

I have been working through a bag of matrix that I received from @sixgill pete from the Waccamaw Formation (Pleistocene) of North Carolina. Earlier I showed a couple of interesting bryozoans that I picked from the matrix (Waccamaw Bryozoan) and now I am finishing up on the gastropods. From the 1 quart bag of matrix, I pulled out over 60 different species of gastropods! The biggest ones were a couple of Olive shells at about 2 inches tall as well as about a half dozen other gastropods that are big enough to easily view with the naked eye, but by far the vast majority of the shells are quite small, some only a few mm's. With some great suggestions for references from both Don and @MikeR I have slogged my way through the identification process which brings me to this post. Out of the group, I have several that I am uncertain about (and probably others that I am wrong on, but ignorance is bliss! ) so I'm going to post a few in this thread and probably start a few other threads over time so I don't have one that has a billion pictures to wade through and try to keep straight. I'm hoping some folks out there can confirm and/or offer a better suggestion on an ID and certainly if you know of a name update, please let me know. The names on many of these critters have been very fluid over the past 100+ years and I consult several different websites (such as WORMS, WMSD, Neogene Atlas, etc) for each species I find to try and check for the latest updates, but some names published early on are seldom heard from again. The first question is on this group of five small gastropods (the silver box is 5mm on a side) which I believe are all the same, but.... I have tentatively called these Turritellas because of the general shape, the aperture and the sculpture (revolving lines) but they don't look straight sided enough to match most of the published forms I can find. They are undoubtedly juveniles and this may be throwing me off, but if anyone has a suggestion, I'm all ears. Some species of Bittium is another possibility. My next question is this small gastropod that looks sort of like some form of Calliostoma but I can not find a match for it in any of the references I consulted. Plus it is a bit low spired for most of the species of Calliostoma that I have seen. The third question is this gastropod which I believe is some species of Epitonium. I found three other species of this genus, but this one is different looking form any of them, the axial ornamentation is not continuous across the sutures and it changes character on the lower half of the body whorl which you can't really see in these pictures. It seems closest to E. carolinae (Gardner) but there are several differences from her description. Next is a very small and undoubtedly juvenile form that I think may be Scalaspira strumosa but I haven't found a lot of pictures of this species and it looks a little different from the drawing in the 1904 publication by the Maryland Geological Survey where Martin further described it. Lastly, for today, here is a pair of really beautiful small gastropods which I keep thinking should be easy to ID, but I can't find a match. They look like a little nutmeg shell (genus Cancellaria) with the shape and the prominent teeth or ridges on the columella, but I can not find any forms that have the very distinctive sculpture of the wide flat bands with narrow incised grooves between them. OK, that is it for now. Thanks for taking a look and for any and all suggestions.

So I found this fossil skull... Kidding! Anyway, back digging in the needmore formation outside Winchester VA and I’ve started finding a lot (like in one small part of the exposure, a whole lot) of these sorts of shells. Initial thought was some kind of ammonite. Searched for mid Devonian and got agoniatites vanuxemi but I don’t get any hits in this formation/location. Still looks right though, although I guess it could be some kind of gastropod? Mostly a little over 5 cm at the largest. Also, they’re generally the same color/consistency, save for this one very colorful specimen (very distinct blue, pink, orange) and I was wondering if anyone knows why it would have preserved that way. Surely the shell wasn’t that color

Went out to Windmill Site in the Rio Puerco Valley today(11/27). It was very cold but very worth it. Found some ammonite pieces, a few oyster shells, and a lot of teeth. We are unsure who the teeth belonged to. Can anyone help us identify these finds? Thank you in advance. Beautiful day in New Mexico.

This weekend I visited again a late ordovicium site north of Oslo, as I now know is the katian period (that applies to the earlier posts on this website which I then, mistakenly, thought was middle ordovicium). First, for the first time I found two graptolites in a limestone, and first time in this site, I m not sure but I think it is graptolites, but it seems so. Next, I found this stone which, I believe, includes an Gompoceras Nautiloid (the brown in the middle) and some nice gastropods. The size of the Nautiloid is about 4,5 cm. And then this small gastropod presered in tre dimensions

Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State Road 101 to Garr Hill, to collect in the Upper Ordovician Liberty Formation. It was my first time at the site and everything I found was collected from loose rocks at or near the base of the outcrop. A couple of pictures:

I read a lot of fossil hunting reports on here, but I don’t post many. I think it’s primarily because it is usually many, many months after I have gone when I finally get everything cleaned up, ID’d and take photos, etc. It just seems too after the fact to me at that point, haha. But this time, due to a wonderful “tour guide” we had, I wanted to get something posted in a relatively timely fashion. Because of that, I haven’t had time to do a lot of research I need to do on specific ID’s but luckily I’m somewhat familiar with most of what we found to make at least an educated guess. I have seen numerous folks on here show some of their finds from the Ordovician and Devonian of Iowa and nearby states and it always looked intriguing to me as I have collected the Ordovician in the (relatively) nearby Cincinnati area and the Devonian in the Great Lakes area and Oklahoma. I wanted to see how the Iowa stuff compares. So my wife and I opted to take the long way home from Indiana to Texas and swing through Iowa (and on to South Dakota, but that was more for sight-seeing). I had done some research on sites to check out and contacted Mike @minnbuckeye to see if he could help me high grade my list. Being the absolute gentleman that he is, he did one better and offered to act as our tour guide for a day of collecting through the Ordovician! What a guy!! I can’t thank him enough for taking the time to do this. We had a great day and hit a bunch of nice spots, most of which I had not found on my own and certainly didn’t know some of the very important details of the sites. Many folks have said it in other trip reports and I can only add to the chorus of how valuable it is to go with someone that knows the area and how nice it is of TFF members such as @minnbuckeye to offer their time and energy to do it. Based on Mike’s recommendation, we spent our first day doing some collecting in the Devonian rocks of the Coralville, Iowa area. The first spot we could not access due to some current road construction but we made our way to the next one and spent several hours along the Iowa River/Coralville Lake collecting from the Coralville Formation of the Cedar Valley Group. You quickly learn how Coralville got its name as the rocks are a coral/bryozoan limestone. There are brachiopods and other fauna, but corals make up the bulk of the fossils at this site. And there were some very nice ones as you can see in the pictures below. Beautiful Hexagonaria, huge horn corals and others. We also went to the Devonian Fossil Gorge and a nearby state park, both of which have nice exposures of Devonian rocks with fossils, but no collecting. Here is a shot of the area, fossils litter the ground. This represents our total haul from this site The horn coral in here were abundant and quite large. Corals What I believe are Hexagoanaria corals. I think with a little cleaning, these will look really nice and I like the juxtaposition with the horn coral. Brachiopods and bryozoans A nice piece that was a little too big to take.

Here are some pictures from my latest trip to the NSR. Nothing special this trip but I was wondering what the last two pictures are of. Seems like a more recent fossil possible a tooth of a mammal?
