This all started over a year ago. I was selected as Member of the Month and a couple of TFF members from Texas invited me down to the big state to collect. I primarily collect in my home region, the northeast, but I've taken fossil forays to New Mexico, Kentucky, and Germany and was willing to consider a trip to Texas and the opportunity to visit some classic fossil sites and collect fossils that are outside my usual focus. I began planning this about ten months ago, contacted potential fossil collecting partners and did my own research on fossil sites, geology, and the types of fossils I would likely encounter. I had never been to Texas let alone fossil collected there. From the Forum I knew there was a lot of great hunting. Then there was all of the logistics, what to stay, what to bring. Since I wanted to bring back a lot driving appeared to be my best option, but I hadn't driven that far solo in over thirty years. Timing of my trip; mid-late September, came right after my daughter went away to college and I was in the middle of moving to a new place. So things couldn't have been more hectic. Finally, early in the morning on September 8th I set out. Things went okay until I was in Kentucky. Just as it was turning nightfall, torrential rain hit, traffic was stopped on the interstate for two and a half hours, and the last two hours of the trip I struggled with wet conditions and poor visibility. I finally arrived at my parents' house just after one in the morning. The next day on my way over to my sister's I took a small detour and stopped at an outcrop I was well familiar with in Leitchfield, the Upper Mississippian Glen Dean Formation.

I am wondering what fossils you can see in these rocks. they are all carboniferous limestone (prehaps not the red/brown one). I can see Bivalves, coral, crinoids, brachiopods (I think), And nothing else. Why aren't there other carboniferous life. (I understand soft parts go) These rocks are packed with fossils, what can a real paleotologist see?

A bunch of Paleozoic shells in a rock I found in Dane county, Wisconsin. I know It’s almost impossible to get a genus ID on any of these fossils without a specific quarry or site but I thought it would be cool if you guys could see them. I also have them posted on my gallery

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:

My fossilized bivalves seem to be turning gold in some areas, and some parts have chipped off . Is this "pyrite disease"? Is it due to being on wooden shelving? I wouldn't say my climate is particularly humid. My great uncle gave these five to me when I was seven, so they are special and I would like to save them None of my other fossils or minerals are exhibiting these signs?

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!

From the album: Bivalves of Platteville/Decorah Formation Minnesota
Overexposure light when taking picture so blue appear to be the best for me so far. Rare Decorah Formation Ordovician Twin Cities Minnesota. Deceptrix planodorsata is what I figures this bivalve is. Kind of reminds me of certain modern nut clam species. -

Guessing Modiolopsis arguta. It is the bigger of similar shaped bivalves that I have found. Uncommon to rare Decorah formation so far. The top right is the hinge. Ordovician, Twin Cities Minnesota. -

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!

Dear collectors! I'm curious If someone interesting for my collection of Mollusc, mainly gastropods and bivalves from tertiary of Europe. I have more than 1000 specimens! I'm open-minded and accept all offers! I am interested in quality fossils and NOT quantity!

Taking advantage of my time spent home, I finally got a couple of glass display cases to showcase fossil specimens from my collection. Finding ones that were affordable and blended with the style of our home, was challenge, and I took my time choosing. Despite a bit of criticism I receive from some of my fossil collecting friends, I am a generalist collector who doesn't specialize in anything. Having said that, my collection does feature some rare faunas; Devonian and Cretaceous bivalves, Lower and Middle Devonian brachiopods and gastropods, Cretaceous vertebrates, etc. The focus is largely on fossils of the Northeast (New York, New Jersey, Pennsylvania, Connecticut, Maryland, and Eastern Canada), but a number of trips to the Ohio Valley, Texas, out west, and Germany have expanded my collection which is about 90% self collected with remaining fossils primarily gifts from generous friends. There is only one purchased fossil in the display and one I traded for. I ended up with twelves shelves- ten devoted to animal life (seven of those are invertebrates), and two for plants. I was seeking to emulate the old style of specimen display that one might encounter in a 19th century museum, when displaying specimens was the priority. I didn't and couldn't display my entire collection which is too large, so I picked representative specimens to tell the story of the vast variety of prehistoric life on earth. Some of my best specimens didn't make it into the display. These are the cases which are situated in our finished basement:

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:

Tiny items, 1/2 - 1/4 inches, picked up in Big Brook that caught my attention and warranted being brought home. Teeth? Bivalves? Concretions? As always thank you for sharing your expertise

There are blocks of marl in the river and you have to go up and break them to find the fossils There are a lot of shells

Hi All. I was unsure where to put this message so hopefully this place is okay. I teach 7th grade Life Science and we are soon starting our coverage of major animal types (arthropods, echinoderms, molluscs, chordtates, etc). I am hoping to put together a teaching collection that can be used each year as we do this. If there are members here who are willing to donate any/all types of durable specimens (harder for young teens to destroy) that could be used to teach students the key features of these phyla. If you are willing and able to share can you please PM me directly. I do appreciate it :-)

Hello all! I haven't done a trip report for a long time so I figured this would be a good time! I went to one for my favorite New Jersey Cretaceous streams on Friday and put in a few miles of walking. It was raining slightly but with hot it's been lately, that was actually appreciated! At the end of a mostly unproductive trip, I decided I was done and would turn around About a minute later, I saw something in the water and picked it up - it ended up being a nearly two-inch long, rooted Plesiosaur tooth!! I couldn't believe it; I've never found a Plesi tooth here this big or any with root so I've been excited all weekend. For the invertebrate fans, I also like the preservation on the bivalves too. Here are all of my 'keepers' for the trip. @Jeffrey P@Trevor@Carl

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
