It has been 10 days since my trip to Wyoming came to a close. I have done a rough cleaning of my finds and will display some of them for you. To begin with, I had a continuing education class in Jackson. The scenery around the Tetons is truly breath taking. But I was eager to depart and begin a fossil hunting adventure with the 3 free days I had left. I love my bald eagles and found this photogenic pair as I departed town. My first stop was NE of Farson in an attempt to find some petrified palm wood. Here is the "road" which brought me to where I thought I should be. No petrified wood was found but I did put a few specimens in my bucket. I believe these are some algal structures??? They littered the butte that I was hunting on. This was not the start that I wanted, but just enjoying the openness of the Wyoming countryside made up for the lack of finds. I finished the day by taking in this sunset before departing. Tomorrow will be a new day and the fossil gods may be kinder, at least I hope. The next site is south of Wamsutter, and the hopeful finds will be "Turritella agate". This Green River Formation (Lamey Member) fresh water snail species is really Elimia tenera, not turritella. I must thank @jpc for directing me there without a hitch. This site appeared on google earth to be a hop, skip, and a jump from the gravel road. It is MANY MANY JUMPS!!! Had he not told me to continue until I saw these hills, I would have experienced my second failure. As you approach the hills, the road forks and the right fork takes you up on top giving you this view. UP top, Elimia are everywhere, for miles and miles!!! Every dark rock in this next photo' foreground contains them. An individual rock typical of what you see in the previous photo:

These are also from Mike's lost gift fossil collection, no location determined as of yet. Your ID will help me do that. I have many more of these. Seem to be all the same genera and species. They have the general form of periwinkles, but they are strangely spirally-beaded. (I understand there are beaded periwinkles), but I thought periwinkles were much smaller, like the specimen in the front, middle.

Paleo Society of Austin had our first field trip since February. Spent four hours and found a smattering of good specimens. I already have a good variety from there so at this point I am looking for the odd species that has eluded me or better ones of what I already have. Found a few of each. One odd bit was this weird tooth crown I found on a tiny little spit of gravel. Photos are not great but maybe someone has a SWAG, or better, for me.

Last year while fossil hunting in a creek in Chenango Forks, New York I came across an interesting looking rock. The rock was primarily made up of gastropods with a few bivalves and brachiopods. It was a very crumbly, silty rock. I believe it is upper Devonian because I’ve only ever found upper Devonian rocks at that creek but I’ve been unable to find anything close to what I found in Karl A. Wilson’s Field Guide to the Devonian Fossils of New York

I have been photographing my collection of Pliocene gastropods from the Southeastern US, but I realize that I will never be able to completely picture every specimen within my collection. On a Facebook page about fossil crabs, @MB has been showing individual drawers within his collection. I like what he is doing so I thought I would do something similar here with drawers within my collection of fossil gastropods. My display collection is organized chronologically, the first seven drawers being Pleistocene. Since many of the formations within the southeast share species and I have limited room within my drawers, I display the two best specimens from any formation within the group so there should be no duplicates unless the same species from different formations demonstrate noticeable variation. Within my Pleistocene drawers, the following formations are represented: Upper Pleistocene Fort Thompson (Florida) Flanner Beach (North Carolina) Chibania (Middle) Bermont Formation (Florida) Calabrian (Lower) Caloosahatchee (Florida) Nashua (Florida) Waccamaw (North and South Carolina) James City (North Carolina) Gelasian (Lowest) Chowan River (North Carolina) Pleistocene Drawer 1 contains the Families Fissurellidae, Calliostomidae, Turbinidae, Epitoniidae, Eulimidae, Cerithiidae, Potamididae, Turrritellidae, and Vermetidae. Quarter for scale.

Two Sites in Central New York in One Day 50 million Years Apart
Jeffrey P posted a topic in Fossil Hunting Trips
It was an all day outing on a perfect spring day in Central Upstate New York. Al Tahan and I visited a small private quarry where the Middle Devonian Oatkacreek Formation Mottville Member, part of the Marcellus Shale and the lower Hamilton Group is exposed. It's been about a year since I visited the site which I've been coming to for the past five years and it was Al's first visit. Erosion had broken down almost all of the pieces of shale which covered much of the site on previous visits. However a lot of fossils here, preserved in calcite are weathered free from the matrix and surface collecting can be very productive. This is by far the best site I've been to for the gastropod, Bembexia sulcomarginata. There were dozens strewn about the site. I couldn't resist picking up a few adding to my already extensive Bembexia collection. Brachiopods were also plentiful, especially the large spiriferid, Spinocyrtia granulosa (upper right). I couldn't help adding this inflated example to my large collection. Upper left is Mucrospirifer murcronatus, certainly one of the most abundant and distinctive Middle Devonian brachiopods in New York. Lower left is Protoleptostrophia perplana, a Strophomenid.

I made my first trip to Post Oak Creek today. There had been rain in the forecast for yesterday, so I hoped for some newly washed out fossils, but Sherman got no rain. So, I knew things would be pretty picked over, but I decided to go anyway, and just hike a bit further down the creek than I normally might, to see if I could find a few teeth anyway. I stayed about three hours. The knee pads I bought yesterday were definitely a good investment. These old fart eyes need to be close to the sand bars to get within reading glass distance of those small teeth. I had also made a sifter, and carried out half a bucket of sand to go through at home. I had fun. That creek is an amazing fossil place.

Hello Was out fossil hunting at Lavernock this past week. It rained a lot so couldn't stay for very long. I never really take my phone on fossil hunts but will try to get some pictures of the surrounding area next time. Here are some of my favourite finds! 1. Jumble of ichthyosaur bones. 2. Ichthyosaur rib 3. Not really sure, probably ichthyosaur rib 4. Gastropod my sister found I tried prepping the ichthyosaur rib but it didn't go too well. At least its still intact.

Carboniferous and Permian boulders in Lithuania- discovery needs confirmation!
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
Dear Guys, During the last several years i detected unknown truth talking about Lithuanian boulders- the Carboniferous and Permian marine rocks are very numerous and their age is various- there can be found almost each stage of Carboniferous and Permian. The main rock types are three- dolomite and limestone with masses of brachiopods that is various in color, stromatolite limestone with mollusks and unidentified cephalon like fossils, and the last- lacustrine limestone with coelacanth scales and possible plant remains (Carboniferous rhabdodermatids are very numerous). Carboniferous period and Early- Middle Permian was not known in Lithuanian glacial boulders so I very need the strong expert, especially who works on Carboniferous- Permian brachiopods. If my age determinations are correct then I will write the scientific book about this discovery and i think there is huge possibility that many of these boulders could be transported by someone glaciation from Northwestern Russia (or Northern Ural) because there are big areas of Devonian, Carboniferous, Permian and Triassic rocks near surface and Northern mountains potentially could be the cold center at some glaciation period in the Pleistocene. I will show all the pictures with fossil identifications and size, maybe someone will tell the opinion about the taxon and age possibilities. Any contact detail or other important information is very welcome! First image- Angiospirifer (Late Carboniferous), 1.1 cm length Second image- Anthracospirifer (Middle- Late Carboniferous), 1.8 cm length third image- Archaeocidaridae sea urchin plates (Carboniferous), 5- 8 mm diameter Fourth image- unidentified brachiopod species from Carboniferous- Early Permian (8 mm- 1 cm length) Fifth image- Atomodesma? bivalves from Kungurian boulder with Waagenoconcha brachiopod (1.7- 2.3 cm length)

I bought a new old cabinet last winter and spent several months filling it with newly labeled specimens, most of them now stored in jewelry boxes. I took photos of it to show Tim, Fossildude19 and he suggested I post them in the Members Collections section. I followed his suggestion. The collection started in 2011 with a few fossil purchases off a well known public auction site. By the early spring of 2012 I was collecting in the field and the vast majority of my collection was self collected in that manner from sites, primarily in the Northeast and Ohio Valley as well as ones collected on trips to Texas, Germany and out west. There are also some gift specimens that I own thanks to the generosity of a number of friends, most of whom are on the Forum. The top of the cabinet is occupied by miscellaneous specimens, some that wouldn't fit in the drawers, some slated to be in a glass display case I hope to eventually get, and my collection of fossils found in New Jersey just above the Iridium Layer.

There are several hundreds of small to micro marine specimen in this one stone. There's complete bivalves, odd looking gastropods and things that I have no ideal as to what they are. I'm told the age of these specimen are most likely beyond two millions years old.

I bought these when I was very young, infact, the small ammonite was the first fossil I ever had. They are all cheap commercial fossils that never came with labels, and the ones that do have labels are unsatisfactory to say the least. I'm hoping some of you chaps know what some of these are and the vague area they're from.

With fall just around the corner, I was able to get in a hunting trip with my friend Jeffrey P, to the wilds of upstate NY: Specifically, the Deep Springs Road Site, in Earlville. I met up with Jeff at our usual meet up place, and time, (6:00 am at a park and ride near Jeff - about an hour away from my home.) and loaded his gear into my vehicle. Off we went. We enjoyed some very nice scenery, once the morning fog lifted. Hills, streams, farms, and wildlife. We both saw a bald eagle flying by, and some turkeys, chickens, and a deer or two. After a stop for gas and some food in Roscoe, NY, we headed up to Earlville. It was, as usual, a good ride, punctuated with some great conversation, and some interesting music. We arrived at the site around 9:50 AM. The place looked like it had be worked quite a bit, with large areas of rubble from other people's digging. The weather cooperated nicely, - it was beautiful, with temps in the low 70's, and we enjoyed sun and some cool breezes. We got to work quickly, and finds came in drips and drabs. We both made some decent finds, (pics to follow.) Jeff getting ready to start the day. We hunted until about 5 pm. With a 4.5 hour drive ahead, (for me) we got on the road. A brief stop at everyone's favorite Scottish Restaurant, and a quick stop for gas, we finished the day out with more good conversation and music. Traffic was great until after I dropped Jeff off. I spent about 25 minutes in stop and go traffic on I-84 through Southbury. I got home at around 9:45 PM. Jeff is such a great guy to hunt with. Informative, supportive, knowledgeable, and often quite funny. I always enjoy hunting trips with him. Thanks again for another great trip, Jeff. Please feel free to add your finds here, Jeff. Hope you enjoyed the report and finds. Until next time, Kind regards,

I had posted a poster of Florida shells of mine earlier but could not zoom in enough so I am posting individual fossil shells in hopes of getting correct identifications or adding to photo database. I am new to this so please gently guide me if I am not following a proper procedure or posting in an incorrect place. I have many high quality photos but am not sure where to put them. I can't seem to create a gallery for myself. Help Please? Thanks, Scott

I don't know where to begin. I am completely new to the forum. I will eventually be posting some fossils for help with ID and others that are identified by experts already. Having said that, this poster represents some of my fossils. I am not sure if can even read the names underneath. I may have to post separately. Any ID corrections would be graciously accepted. What I really need help with is locations. While living in FL for several years, I would go to a couple of locations in Polk Co. where I knew road base, I believe it is called aggregates were often kept. I visited and collected. What I don't know if where the shells originated. APAC Pit in Sarasota, Aggregates Pit in Bonita Springs, Star Ranch Quarry, Clewiston, Cochran Pit in Labelle to name a few possible locations. Based on the shells collected, it would seem that most come from either the Tiamiami or Caloosahatchee Formations, not sure which members....Pinecrest Beds, Bermont, Ayers Landing Ft. Denaud etc. How do I know what collection data to include on my label. I can list where I found it, but it is not its origin. ID is pretty ok with Petuch's works, but if I don't know the origin, it makes ID much more difficult. Any input or ideas to help would be appreciated. Thanks in advance. I have included a sample collection label for anyone to comment on how to improve. One is more vague since I don't know origin, the other is from a fossil I purchased. Date on label was date I added to my collection. How important is it to list the taxonomist such as Petuch or Conrad etc? scienceteacher79

I have come across several tiny bivalves and gastropods while digging marine fossils out of sandstone boulders, they range in size from about less than 1mm to about 10mm. I was wondering, do all of these small specimen grow into the larger ones? Also, I can plenty photos of present day small specimen but I can not seem to find many photos of prehistoric small bivalves and gastropods, anyone have any links to tiny prehistoric shells???

I contacted a few scientist trying to figure out some of the marine fossils that I had found and many them appeared to be shocked at how many these had color in them. Is it really rare to find marine fossils beyond 2.5 millions years old with color??....OMG, just had another freaking earthquake!!!!!!!
