    Herkimer Diamonds 10/28/2023

    I meant to post this shortly after the trip, but I was busy at the time and forgot. So last October I went on a fieldtrip with my local club, to one of the newer Herkimer Diamond mines. I hadn't been to one in many years and we got a chance to go for free. For those who may not know. Herkimer Diamonds are in fact, double terminated quartz crystals. They are found in only a few places in the world. The ones from New York are regarded as being of the best quality. A few mines have opened up in recent years. The one we went to, is in the middle of the woods. While I did not find any really big ones I found many small ones on great quality that I wanted to share as they are quite beautiful.

    Rocks or fossil

    I found these at the same location. Petersburg wv in shale/ seems too cool to be true.
  3. For those of you in the Chicago area, ESCONI (Earth Science Club of Northern Illinois) is having their annual show March 16-17 this year. More details on their website: ESCONI 2024 Gem, Mineral, and Fossil Show!

  4. I found this stone at the beach amongst lots of other fossils and stones. I’ve never encountered a stone/fossil/mineral like this one here in Norway, and I’m absolutely fascinated by it. I’m fascinated by rocks, minerals and fossils in general, but I grew up far away up in the Norwegian mountains. These kind of rocks/fossils I found in Holmestrand is not my field of expertise or knowledge, and I couldn’t find anything that resembles this rocks online or in books on the online library. So I figured that it’s faster to just ask you guys what you think? I do believe it’s a fossil of some sort, but it looks like partly mineralization as well? Or like a different mix of different types of rocks? The bottom reminds me of “Skifer” stone, but it doesn’t quite add up and I can’t verbalize why. The top shimmers in the right light, didn’t see it until my kitten didn’t like that the stone received more attention than him and decided he should get my attention by standing between the rock and my light source(amongst other things). I haven’t dared/had capacity to give the stone a proper wash yet. I’m still a newbie.

    Rare fossil. Weird shape

    I found this weird fossil / mineral / stone in a lot that I bought in Virginia. I am not able to identify it. Please take a look at the pictures and share your thoughts with me. I'll appreciate your help.

    Fossil replaced by calcite?

    My preschooler found this on a hike in western pa. We scoured our Audobon and cannot figure out what it is a fossil of, if it is one at all. I am afraid to ruin it by cleaning it. UV reactive, fluoresces bright yellow-green. Thanks to all you brilliant folks for your help!
  7. Hi everyone! I'm moving from my current country of resident, the Netherland, to Canada. Through the years I've amassed a semi-large fossil and mineral collection, and I want to take some of that collection with me to Canada. My only concern is that I might run into problem at the airport, so I wanted to ask around here if anybody had any experience with air travel with fossils/minerals in the Netherlands/Canada. I couldn't really find any information about this from the Netherlands, and Canada just vaguely says "it may be illegal to bring cultural property into Canada, such as antiques or fossils". Would anybody mind sharing their experiences the've had with these countries? Thanks in advance!
  8. Will someone who has knowledge about this subject, please explain how and why we have so many interesting color variations in the world of fossils? Shark Teeth, Ammonites, Petrified Wood, etc. There are so many different color variations. And I like it!!!

    Is the huge rock anything special?

    Hey there I wanted to introduce myself because I'm completely new to not only the website but also the field or any field entirely. Many many props to you paleontologists and archaeologists and scientists because I would consider myself have a fairly intelligent individual in general but trying to self teach about fossils when you don't know the first thing is not the easiest LOL I've always been pretty outdoorsy and love the idea of fossil hunting and always have but it wasn't until recently that I moved to one of the most perfect places for it... Northern Colorado. To be honest it took a few years before I even had a clue that rock hunting is even a thing though. In the past two or three years I've gotten more and more fascinated with Mother Nature and her ability to create things far more beautiful than I could even imagine. For the most part I've collected cool rocks I've seen here and there but because I've got an 8-year-old that loves to follow suit, it can be tricky to remember 100% where these rocks have come from. I can tell you for sure most of them if not all of them I would bet money came from the same place which just happens to be what I would imagine is as perfect as any for something like fossils really be at. So I've gone back and forth saying that it's totally possible to find a kick butt fossil but then I tell myself there's really just no way I'd be lucky enough and all I've got is a really pretty Rock I can put my garden. In the back of my mind I've wondered though for a long time now and so I thought that I'd come on here and ask for some advice from some of you guys if you wouldn't mind. I'm making three posts of my number three favorites I think is what I'm going to do and then cross my fingers. I'll expect there just rocks for my garden and hope for the best. If you could please let me know if you have any idea for sure if this might be any kind of a fossil or even maybe a semi-precious Stone or interesting mineral. Anything would help at all and thank you for your time

    Harvard MNH April 2023

    I wanted an adventure and my youngest niece is graduating from Boston University in a few weeks. Definitely worth a celebration. I booked a 6 am flight Saturday, landing in Boston at 10 am. I had about 6 hours before Emily was done with class. Commonwealth Avenue has a park like setting with statues and walkways going back a couple of centuries. I took a 4 mile walk through Boston Commons to the Boston Opera House. My primary contribution to the activities was a pair of tickets to the touring play "My Fair Lady" on Friday evening. We went to dinner and to the Play. Grand time was had by all. Emily had selected a fantastic lunch at the Tasting Counter, followed by a tour of the Harvard Museum of Natural History. We spent 3 hours viewing exhibits. We started in the Hall of Rocks and Minerals, A couple of interesting examples. Next into the glass renditions. In 1888, Harvard commissioned reproducing Flowering plants in glass. You can read about it here... https://hmnh.harvard.edu/glass-flowers In thousands of plants and Flowers, the creators included one insect buried deep in one flower. Unfortunately I did not get a photo. I did get a few photos of the plants.... a flower, a tree As I moved out of the Glass plant exhibits, I was looking for the marine and shark exhibits, I did not realize that many were a glass collection of Inverts: https://mcz.harvard.edu/blaschka-glass-invertebrates So, as I provide photos, think about whether you are looking at glass or a fossil..... Just below is a Dorsal Spike from Hybodus reticulatus (200 mya) So, Is that Meg glass ? How about the Sawfish Rostral ? This is Orodus ramosus tooth (300 mya) Just for you , Daniel... Hexanchus griseus Above Eryon arctiformis, Jurassic. Solnhofen, Germany Very impressive.. easy to stand and stare at each exhibit.. On to Cenozoic Mammals, I sometimes find many of their bones....I do not think these are glass.. Parahippus Teleoceras.... Those tusks seem small.. Look at those footbones. I have some.. Menoceras Jaw Articulated bones for Sloth, Osteoderms for Glyptodon.. an edge Osteoderms... and over this , I get to see it in place... This was a great afternoon, a nice gift from Emily.... Enjoy..
  11. This week-end, during the easter feast with my club we organised our annual exhibition of fossils and minerals. Note the opalised belemnites and the huge Phacops rana africana. Each year we give pride of place to a subject. This time that was the pyrite. It was the occasion for the non-initiated people, and, particularly for the children, to discover the gold of the fools. We make ourselves the sandwiches and cakes, this year, one of our member made special cakes for kids.
  12. I'm planning a trip to Washington, D.C. soon. And will have plenty of time for stops. And I was wondering if anyone had any suggestions for places to look for fossils and minerals. I'll be driving along Florida's east coast, coastal Georgia, semi-coastal South Carolina, the middle of North Carolina, semi-coastal Virginia, and Maryland. Anyone have any recommendations for good places to stop in these areas?
  13. Hi people, I have a query regarding the contents of some siderite nodules from a Duckmantian fossil forest site in N Wales for my PhD project. I had thin sections made of parts of several nodules and they all seem to have an abundance of 'faecal pellets'; rounded, often curved (banana-ish) shaped, mostly stratified pellets. These pellets have been replaced by siderite (FeCO3) and sometimes include pyrite and seem to have been the locus for early sulphate reduction by bacteria before conditions arose for the siderite precipitation. I've attached SEM images of the thin sections showing some of these pellets. We have only found a couple of fragments of crustaceans (Euproops I believe) and the host sediments were fine sands and silts. All the images show individual pellets with scale bars but "pellet5" is a zoomed out image showing the abundance of the pellets. They are all replaced by an Fe-rich siderite and are all quartz free. "pellet6" is different with a mottled texture and some potential apatite mixed in. Let me know if anyone has seen similar textures before and/or what could have made them! The palaeoenvironment was purely freshwater with meandering river systems, with a dynamic lycopod dominated fossil forest ecosystem. pellet3.pdf pellet2.pdf pellet1.pdf pellet5.pdf pellet4.pdf
  14. I know next to nothing about radioactivity-- enough to know licking fossils is inadvisable, although I'll admit that wasn't terribly disappointing news. What I'm wondering is whether specimens not radioactive enough to endanger a person are capable of damaging other specimens. Is there a need to segregate displays here, or am I just confused about the mechanics of this? My specific reason for asking is that at the moment I'm planning for my current favorite mineral specimen (which I am babying forever), an almandine garnet from Broken Hill, New South Wales, Australia, to share a small shelf area with a tooth from the phosphate deposits in Oulad Abdoun Basin, Morocco and a few dinosaur bone pieces from the Hell Creek Formation of Montana (one from Dawson County) and Lance Creek Formation of Niobrara County, Wyoming. The shelf is not enclosed, by the way. Thanks for your help!
  15. I finally completed the reorder of my collection of fossils and minerals. It is a wooden hexagonal display cabinet of several wood/glass shelf; in the pictures attached I only show some of them. I 3D printed more than 20 custom drawer compartments for the smallest specimens. I decided to go for a modular design, so I can adapt every compartment to the specimen. As printing material, I used a "wood PLA" filament 3D printed with 1 mm nozzle on the Alfawise U20 3D printer. LINK I finally added a strip LED inside the cabinet door and powered it via a USB power-bank - so it is fully wireless. In this picture you can see some of my recent purchases: Two Sinosauridae indet. teeth from Kem Kem One Acheroraptor tooth from Hell Creek formation, Powder River Co., Montana Some Mosasaurus teeth from Kem Kem One Pterosaurs tooth from Kem Kem A piece of Rhinocerontidae indet. jaw from South Dakota Some ammonites, shark teeth, a Flexicalymene ouzregui, a couple of echinoids (I found the white one in a brick!); the Velociraptor skull is 3D printed as well. This is the other side. The big sand echinoid was also found by me in a brick! On the right there's a nice fossil coral: I never seen something similar, please let me know if you know it's name. Three fossil fishes and a nice ammonites cluster with some quartz in the background. At the end, some minerals... Now I only have to finish the cataloging of all specimen. I already finished with fossils, now I have to start with minerals - it will be very looong! What do you think? Do you like it? Ciao!
  16. Today was the first day of the Syracuse Gem & Mineral Show. I work at the show the entire day and it was a blast. Unfortunately for fossil lovers this years show did not have a good fossil turnout. While there were some nice fossils to be had, we lost a major fossil dealer, who in my opinion carried the largest variety of goods. I did not get any pictures of the show today as I was very busy, but will make a point of doing so tomorrow as I will be there all day for day #2. I did want to show what I purchased. I always tell myself not to by anything but it gets very hard to resist. So I managed 3 nice trilobites. The last one did not have much information, only that it was from Morocco.

    Great grandfathers rocks

    So I’ve got a few questions all at once. Over the years I’ve inherited a number of my great grandfathers rocks (he was also into paleontology and geology) but I’m not sure what they all are. I’m guessing 1 is some sort of mineral, not a fossil. It, along with 2 and 4, were found digging the foundation of his home in south Charleston, WV. I feel like 2 might be petrified wood, but if it is I’m very curious about the side that’s black and very crystallized. 3 is from Seneca rocks in WV and I feel like must be a fossil but I really don’t know what. 4 again looks like petrified wood to me, and 5 for a complete change of geography, is from Washington state, somewhere at the beach (as vague as that is). I imagine it’s just some sort of mineral inclusion in an ocean tumbled rock, but thought I’d ask. My last question is geology related so apologies but I don’t wanna have to go make a bunch of new friends on some geology board so I had hoped one of you would be able to help me. Great grandfather hand made this board of rocks and minerals but it’s missing alabaster and lepidolite. Anyone have any idea where I might acquire single, small samples of both of these minerals so that I might complete the set? As always many thanks for taking the time.
  18. Hello, Did anyone attent to the Munich fair in previous editions? Its from the 22-24th October this year. Got a tip that it should be interesting. Im considering going, but its an 8hour drive from my home. Im not interested in Minerals or jewelry, just Dinosaur stuff, so would really help out if someone here knows how the fair is ? Is it good? Is there allot of Fossil-Dinosaur material? Thanks for your opinions! Best, Egon

    Seeking Eastern PA sites?

    I'd really like to get more into fossil hunting and rock hounding after how much fun I had at the beach. Are there any good sites I can access around Eastern PA? Specifically up to an hour or two of driving distance from Berks County. When I search for sites in PA I usually see suggestions for Central and West PA. I'm not looking to join any groups atm for personal reasons, but I'll take suggestions for when I feel up to it (there's a group in Reading I'm keeping an eye on). Any tips would be appreciated! Thanks!

    Interesting mineral that may be a fossil

    A few days ago I found this rock in northern Israel. At first I saw the part you see in the first picture but then I saw an interesting mineral in it, so I used the advanced tool of another rock to open a part of the rock and I found that the black mineral in it has an interesting shape. So i would love to hear any idea about this rock, are there fossils in there? What kind of rock is it?

    Unknown Fossil Please Help Identify

    Hi I have a fossil I found while exploring an area near Dubbo NSW australia. I taught it was just petrified wood until I cleaned it and notice on one end has colour and looks like it could have fish fins on the side. The length is 300mm and width is at its widest point 180mm. It was just sitting on side of a dirt track and also has another part to it which I will pick up next time I'm out that way again. Any help in identifying what I have here would be much appreciated as I wouldn't have a clue other than what I think it is. Thanks
  22. Fossil mimicking geology more common than actual fossils https://www.sciencenews.org/article/fake-fossil-biomorphs-more-common-ancient-rocks-real-fossils
  23. Hello! First of all, I am not a geologist. This isn't my field of work. I am hoping somebody here can help me with this! Today I drove a few miles southeast of St George UT and into AZ. This place is amazing. Fossils everywhere. Just incredible stuff. Was out looking for crystals and whatnot... And unearthed these... Looking to what it is, a guess maybe on how old, and HOPEFULLY an explanation of what the small "hair looking" matter is. It looks like a root, and hair, I actually have no idea but this thing was entirely underground and inside this chunk of material that came apart. So whatever it was, it's been there for a while. So cool! Added a quick snapshot of the Gaia app. Coordinates for the area 36.948968,-113.471321 Any help would be much appreciated!
  24. exchange for fossils only,i will consider all offers,minerals are taking too much space the biggest pieces can be send only in Europe. a Piece of Calcite from Dordogne
  25. Aloha, here is the best of my collection. Since I moved together with my girlfriend, only the small and nice samples are on display, one showcase out of three. Looking forward to the day when we will have some more space. So it is a crowded mix of fossils, minerals, recent beachfinds and mosty selfmade or altered skeleton models. Sadly, only a small percentage of my fossils is selffound, although nearly all of the beach stuff is. There is the "poultry showcase", dedicated to Birds and pterosaurs (Parrot skull is a replica of course, as is the Pterosaur plate regrettably) The big showcase is a composite image because I could not get all into one foto. The whales you may know from the Palaeorecreation thread. Best Regards, J
