    My fossil collection part 2

    Hi, as promised this is part two of my fossil collection. 1. Trilobite. (Bought) 2. Orthoceras (bought) 3. Knightia (bought) 4. Ichthyosaur vertebrae (bought ) Soon I’ll post part three.
  2. Hello all, I love reading the posts here and the knowledge base is amazing. Question, I came across these two specimens today and they seem really long "tall" and too perfectly straight to be real. They must be at least 4 foot tall. I have enclosed pictures and a close-up of a small section that is broken. Thank you all for the help. D
  3. So I'm visiting Canada(Alberta) for a while and came across this store that sold gemstones and fossils. I decided to buy a few fossils(chambered ammonites, orthoceras, trilobite elrathia kingii, Trilobite proetus) but when I got to my rental place I came to the realisation that these might be illegal to take with me back home. I'm from South Africa. Will it be a problem if I take them home with me or do I require some kind of permit to bring them with me on the flight home?
  4. Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

    Cephalopod Shell Color!

    Hello all! Recently I have been obsessed with cephalopods and realized there is a real lack of reconstructions of the color patterns on extinct nautiloids and ammonites! This led me to compile a list of known fossil color patterns on cephalopods. After a year of on and off research, I found about 90 species of cephalopods retaining official or undescribed, original patterning on their shells. These are the first 15 species on my list. The color markings are based both on descriptions and photographs of the fossil material. The shades of the markings are based on the fossils, but also inferred. I Hope you will appreciate my work!

    Orthocone Rarity

    How rare are phragmocones from cephlapods? Are they something you need to get into a quarry to find, or can you recover them out of roadcuts? This is for the Midwest, like Illinois, Wisconsin etc.
  7. This is actually quite enjoyable finding out which fossils are real and fake. First pic we have a fossil flower stamen from the Green River Formation in Utah. The second piece was quite cheap, but it's from Morocco (Anti-Atlas Mtns.) and it seemed odd to me that the bottom Orthoceras has the same pattern as the matrix below it. But perhaps you have an explanation for that. The third piece is a Ginkgo leaf from the Sentinel Butte Formation of North Dakota. The final piece is a Juvenile Megalodon tooth from Pungo River Formation of North Carolina. Thanks again to everyone who's helped out, I'm sure I'm not the only one who's learned something.
  8. This is Isorthoceras sociale (Hall, 1877) from the Ordovician Elgin member of the Maquoketa from the well known Graf, Iowa location. They exhibit unusual preservation, including nacre and hollow camerae. According to Invertebrate Fossils (1952) by Moore, et al,, shells of nautiloids have an inner annulus layer, middle nacreous layer and outer porcelaneous layer. Is the circular pitted texture on the outside then the remnant of the porcelaneous layer of the shell or some sort of epibiont like a bryozoan? Plate 220 of Shimer and Shrock's Index Fossils of North America (1944) has orthocone shells illustrated, but the texture appears wavy.

    Need help identifying

    Hi everyone. I am new to the group and would like to ask for some help in identifying this fossil. To my eyes it looks like a cephalopod but never seen one this big. Can some one help? I found it along Etobicoke creek. Any help would be much appreciated .
  10. Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthoceras (found together with a tile with tentaculites); 7. A selection of teeth and vertebrae (most of the Cenomanian fish): 7.1. 3 Enchodus teeth (2 large ones are glued from fragments, and the largest (light) one is also smeared with a children's felt-tip pen), Cenomanian. 7.2. Ptychodus teeth (light - Cenomanian; found personally, and dark ones got by exchange); 7.3. 2 undefined teeth of the Cenomanian fish and good teeth of a shark from Malin, Zhytomyr region (by the way, dark teeth of Ptychodus are from the same place); 7.4. 2 Pycnodus teeth - Cenomanian. 7.5. - A bag of Cenomanian fish vertebrae - about 50-60 pieces. Perhaps some of this will interest you. What is interesting to me: first of all, on marine reptiles and dinosaurs, and also offhand, I am interested in the teeth of megalodon, Crinoids and ammonites. Surely I missed something - I ask you, do not hesitate to write to me in private messages - i will glad to talk. Best regards, Svetlana
  11. I was trying to find the longest straight shelled cephalopod length but was unsuccessful, I heard anywhere from 7-14 feet. What's the real answer? Thanks.

    Orthoceras I

    Hi! A recent walk in the woods resulted in the discovery of this nautiloid. I found it in Wilson County, TN which is Ordovician. I am super excited about this because we found it in the woods on the property where I grew up, which means I probably walked past it a million times, and it's 3D so it shows the the siphuncle, and the outside of the phragmocone. We did not have anything to measure it with but I would estimate it to be about 12cm (5in). So my questions are these: I think first verify what I think this is and what I see as I am new to this. I have looked around the internet for genus/species of Orthoceras found in TN, but can't find anything, does anyone know? The fossil is covered with moss, what is the best way to clean it without breaking anything (once we drag this monster rock out of the woods and to the house)? Thank you so much for opinion/advice/help!

    Orthoceras fossils in the US

    Hi, I was wondering if you can find Orthoceras fossils in the US?

    Orthoceras, and?????

    Bought this for $5.00 at an estate sale this weekend..........so.......there's absolutely no information on it, but someone prepped this. I believe it contains two species of Orthoceras? - off to the side, is this a different species?, or just a different plane of the same species?.......sorry- don't have specific measurements but the prominent one is about 1" wide and 7" long.......thanks!

    Identification

    Hello everyone, I working in dimension stone field in Armenia. This fossils where found in a sample small stone block brought for cutting to the factory, then they were machined polished as standard marble or granite tile. The tile (second photo) is 400x800mm app.16x32 inch. Kindly help me to identify these guys. Thanks
  16. I am back from my trip to morocco. It is a 14 days trip and I got 4 days for fossil hunting. It was so imagine, fossils are everywhere and even though I won't be able to dig, I still get plenty to bring home. Since my guide doesn't speak good English, I am not be able to ask him must so I need help to identify the fossil. On the first day, my guide took me to a place near Erfoud to search for dinosaur teeth. It is very close to the highway. We found a well that the local people dig to get Spinosaur teeth and bone. My husband went down to one but couldn't find anything because the well is new and it is not deep enough. We didn't want to try the deeper one so we decide to bought some spinosaur teeth from the local people there. This tooth is a little over 4.5 inches and I think there are some prepare but I can't tell how much. I also bought 3 smaller teeth and was giving the broken one which I don't know what it is.

    Biologic or odd concretion?

    Hello, I'm posting this for a buddy of mine. This piece was found in the French Joe Canyon area near the town of Whetstone, AZ. Any ideas if this is an actual fossil or an odd looking concretion? Thank you for any and all help.

    Fossils from Gotland - Sweden

    Hi! A friend of mine sent me some photos of some objects he have found on Gotland. I guess the first one is coral, the second may be an orthoceras?, The third I have no clue about. What do you think?

  21. After a bust season in Florida for the Peace River, it has been way too high. I am excited to be planning a trip back to Newberry, Mi. Two years ago when I was there, I was able to collect at a degrading hill side east of the town. There is a quarry of Collingwood Shale south of the town, but I was fortunate to find drift cobbles, and some Collingwood Shale on a friends property. Last time I found several nice impressions of Pseudogygites , mostly just the pygidium. I also found a couple of kinds of graptolites, and brought back a 4 inch thick, 16" long slab of shale with a nice orthoceras impression on the top. As i began salivating about my new trip, I returned to the shale and decided to split it, hoping I would not break the orthoceras impression on top. Well I am glad I did. It was such an interesting afternoon. One of the splits revealed just a fine grain layer of dark mud, with nothing in it. That was the middle split. Then I split each of those halves...in the have below the clean layer, I saw lots of little white dots...ranging from 1/32 of an inch to 1/16...Turns out they are braciapods. I captured a photo of one of the largest, and in it, the hinge even shows. Amazing. On the the half lying between my orthoceras impression on top of the clean grainy mud. Excitement. And drum roll please. I popped open what appears to be a small orthoceras, but perhaps it is a conularid, can't really tell. The exciting thing for me was the preservation. It has a nice decomposition blow ring of color around it, deriving from the decomposition gasses. I learned that from studying my Conasauga trilobites. And then it has some nice detail indicating structure. I was really excited. In the photo of the two halves, one looks larger because it is closer to the camera. On the other side, the top of this piece, my orthoceras was preserved, but a little chip from the side revealed a nice graptolite. A bit more might be revealed, but my previous experience with graptolites. precludes that...I don't plan to touch it. I found so many of them last time, I played around to see if they would be cleaned up....not the ones I have, they just break apart at the slightest touch. So overall, I feel like I am experiencing my trip once again, and I hope to be able to post new photos in June after I return. First photo is the little brachiopod (unknown type). Second photo is the Collingwood shale after splitting. Third photo is the two halves in same photo. Fourth photo is half A - fifth is half B
  22. So the beach was recently excavated and what was covered by the ocean for so many years, dried out and the sand was excavated and made into huge dunes full of old seashells and mysterious oysters and conches. I found many bivalves and i stumbled upon this weird stone that is covered in fossil like formations and shells. Any idea what it could be? Is it a fossil? Is it extinct? Its driving me NUTS.

    Fossil hunting in Norway

    this year's first hunt was not entirely successful. There is still a meter of snow in some places. Found some small fossils that I don't think are possible to identify. I may show pictures of them, but saw several large orthoceras and some trilobites in a mountain wall where the snow was melted (exposed to the sun). May have to wait a few weeks, after Easter before i can go fossilhunting. The area where i took these pictures is called fossildalen/fossilvalley in slemmestad. The fossils here in the area stem from the time periods of Cambrian, Ordovician and Silur, a period of 541 million to 419 million years ago. At that time, Slemmestad was a seabed in a relatively shallow sea. The Orthoceras fossils i took pictures of is about 420 million years old.

    Othoceras Sp from North West of France (silurian)
  25. I just got this orthoceras fossil from the atlas mountains if Morocco. I was wondering if they was a formation associated with it? I've got the age, but not the formation, if any. Thanks, Tyler
