  1. PaleoOrdo

    Unknown fossil

    I wonder what this strange circle can be. The size is 1 cm in diameter, from Upper Ordovician west of Oslo, Norway. Could it be a foram?
  2. PaleoOrdo

    What can this be?

    In Hadeland, Norway, I found this two fossils, about the same size and in the same rock. Anyone have any idea what it is? The age is Upper Ordovician, in the Kalvsjøen formation. It is dykes in the area, but not exactly where I found the rock. Then here is the other side of the rock:
  3. I got a fossil plate at around 5.5" long with trilobites from online. The seller states that: Location: La Prairie, Quebec, Canada Age: Upper Ordovician Formation: Nicolet Formation The plate also has other fossils that I could not identify. They look like fan. Are they just scallops? I also find something in the last picture. I don't know they used to be plant or animal. Thank you very much for your help.
  4. PaleoOrdo

    What is this?

    I found these strange wave forms in a rock in the late Katian, Upper Odovician, Kalvsjøen formation, Oslo field, Norway. What can it be? Any help appreciated.
  5. Hi everyone! The last few times I went out fossil hunting, I tried to find new exposures along Mimico Creek in Toronto. All of these trips were unsuccessful, so I thought I'd try to find a new site along Etobicoke Creek instead. Today I checked out a new location and fossils were found - hooray!!! Here are some photos of what I found: (note that all of these fossils are from the Upper Ordovician Georgian Bay Formation) First, the trilobite pieces (@piranha - please let me know if I've identified them correctly - thank you! ): Isotelus maximus: cepha

    Trilobite

    Found in a dam/quarry on the road between Gunningbland and Forbes in central western NSW. The pictured specimen is the counterpart. For reference - CAMPBELL, K. S. W., DURHAM, G. J. 1970. A new trinucleid trilobite from the Upper Ordovician of New South Wales. Palaeontology, 13, 4, 573–580. link WEBBY, B. 1974. Upper Ordovician trilobites from central New South Wales.

  7. Hi everyone! I found this piece yesterday at my new spot along Etobicoke Creek here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). It's a bryozoan of some sort with some crinoid stems on it, along with an imprint that I think is either a Cruziana ichnofossil or a weathered crinoid stem imprint - what do you all think? I've boxed the imprint in red. Thanks in advance! Monica Views of the imprint: View of the other side of the rock/bryozoan: Close-up of the bryozoan:
  8. Hello once again! Upon closer examination of some items I recently collected from Etobicoke Creek in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician), I have found a couple of items I'd like your thoughts on. Item #1: Found on the same rock as a monoplacophoran (Cyrtolites ornatus), the unknown item is tucked underneath some matrix: View of the whole rock: Close-ups of the unknown item: Continued...
  9. Hi everyone!!! I had the afternoon to myself today because William and Viola are at day camps this week and my husband was busy, so I decided to check out Mimico Creek (Georgian Bay Formation, Upper Ordovician) by myself for a couple of hours. I didn't make many finds, but the finds I did make were super-amazing (by my standards, anyway ). As I was walking along the creek when I first arrived, I was checking out the wall of rock when I noticed a pattern: After gently prying out the rock, this is what I found: Hooray!!!!!!!!!! My first Flexicalyme
  10. Hi all! I ventured out to Mimico Creek in Toronto, Ontario today to look for fossils. It was very cold and the rocks were frozen together, but I managed to pry out one large rock that has some interesting fossils on it. The fossils are from the Georgian Bay Formation (Upper Ordovician). The rock caught my eye because I could spot a few Cornulites flexuosus on one side, but after I brought it home and washed it, I was pleasantly surprised to find that the other side had even more interesting items on it! I'm not exactly sure of what I'm looking at, though, so I'm asking for your
  11. Hello there! I took advantage of the nice weather we've been having to visit Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician) yesterday afternoon. Here are some photos of specimens that I'd like help identifying - perhaps @Tidgy's Dad would like to have a look? Firstly - the whole rock which contains the bryozoans and the unknown black objects: Specimen #1: a nice branching bryozoan - perhaps Homotrypa? Specimen #2: a nice encrusting bryozoan (there are actually two of them) - perhaps Mesotrypa?

    A Mood Lifting Hunt

    I was able to get some much needed "me time" yesterday. With all the worries of the world I have been in a foul mood lately, but I am happy to report that my mood has brightened significantly. . There is nothing like crawling around on a road cut, and hunting fossils, to really lift one's spirits! I spent a couple of hours at an upper Ordovician road cut that has been on my list to check out. It is an exposure of the Grant Lake Limestone. Shortly after I arrived, I realized that I was in for a real treat! This particular exposure is more fossil than limestone. Brachiopods are ever

    scolecodont or conodont?

    Hi again! Over the weekend, I posted pictures of small fossils in a rock I found at Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician). I've created this new post just for the shiny black specimens that I found in the rock because a consensus wasn't reached regarding their identity. Each of the two specimens pictured below are 5mm long. My question is: are these items scolecodonts or conodonts? I was leaning towards scolecodonts but I wanted to see what others have to say... Thanks once again! Monica
  14. Hi again! This past summer I purchased a small rock with 4 edrioasteroids on it, and I was hoping to get your help in identifying them. The seller said that the rock is from the Upper Ordovician Verulam Formation in Gamebridge, Ontario, and he/she said that the following 3 species of edrioasteroid are on the rock: Cryptogoleus chapmani Isorophusella incondita Belochthus orthokolus Can anyone tell me the specific identity of each edrioasteroid? Thanks so much for your help! Monica Photo of the whole rock:
  15. What's your take --- are these real? Considering purchase. Details: "Selenopeltis buchii trilobites", 45 x 35 cm (total size), Paleozoic, Upper Ordovician, discovered in Morocco.
  16. Today I drove the great distance of 10 whole miles to collect along a creek. I have known about this location for many, many years but did not know the exact location. I first read about it in the old 1964 Edition of "Fossils in America" written by Jay Ellis Ransom. Though i was only 3 years old when this book came out, it must have been a great edition for any fossil collector in the United States. It does it's best to give the location of fossil collecting sites in every state by County. For the fossils that I was after today, Tentaculities oswegoensis, it mentioned that they were found in K

    Ascocystites drabowensis

    The dimensions given are for the largest specimen. The block is 11.5 com at it's widest point by 10 cm and 2 cm deep. Most of the of the other species ascribed to this genus in Morocco are now considered junior synonyms. See https://link.springer.com/chapter/10.1007%2F978-3-319-04364-7_199 Notice that they are all aligned in one direction as they were buried by a mudflow sweeping in from the continent. The arms, bodies and stems are all pretty much aligned. This seems to have occurred fairly regularly in this area at this time. Also notice younger, smaller specimens have
  18. Hello there! Last month, I visited the Credit River in Mississauga, Ontario, Canada (Georgian Bay Formation, Upper Ordovician) to look for some fossilized corals. In addition to a bunch of weathered colonial rugose corals, I found an item that I think is something, but I'm not sure what - perhaps a sponge? Here are some photos of it: Side view - dry: Top view - dry: Top view - wet: Thanks so much! Monica
  19. Hello everyone! Now that I've started to split some rocks from my local creeks (Mimico Creek and Etobicoke Creek, Georgian Bay Formation, Upper Ordovician), I'd like some help to identify what I've found. @JUAN EMMANUEL, can you help? Rock #1: This type of bivalve is very common, but I can't decide if it's Ambonychia sp. or Byssonychia sp. The book I have says that they both occur in the Georgian Bay Formation, and they look very similar except Byssonychia sp. "has strong radiating ribs rather than (fine radiating) striae," which is what Ambonychia sp. has. (Hessin, p.
  20. Hello there! I was inspired by @markjw to check out the Credit River here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician) because where I normally hunt there are typically no corals and I'd love to add a couple to my collection. Consequently, I went out for about an hour this morning before the family got up in order to try my luck, and I'm happy to say that I was successful!!! Based on information provided by @FossilDAWG in other threads here on TFF, I think all of my colonial rugose corals are Favistina calcina - here are photos of three of my spec

    Cephalopod section?

    Need help with identification. I have a pretty strong idea that this is a weathered section of a cephalopod but I would like to be certain. Your feedback (as always) is appreciated. :)-

    Graptolite from Mimico Creek?

    Hello there! Well, I tried to take Viola out for a little fossil hunt by Mimico Creek in Etobicoke, Ontario (Georgian Bay Formation, Upper Ordovician) this afternoon because when I checked the forecast this morning it looked like it was going to be ideal fossil-hunting weather - a mix of sun and cloud with temperatures in the mid-20s Celsius. When we arrived, however, it began to rain - we toughed it out and came away with one piece before it began to pour and we called it a day. I was disappointed since I was hoping to spend a few hours there, but the one piece we took home look
  23. Hello everyone! On Monday, I found a beautiful Treptoceras crebriseptum orthoconic nautiloid in a huge rock at Mimico Creek in the Etobicoke/Toronto area (Georgian Bay Formation, Upper Ordovician). It has been suggested that I might have a complete specimen, so I was hoping that someone out there might be able to let me know if this is the case or not. Here are some pictures... Whole specimen: Close-up of the base of the specimen (specimen has been turned over) - note that it is smoothly rounded and shows no septa - is this the fossilized

    Ordovician Tail?

    I found this several years ago in Kentucky near Maysville, which, based on this map, is in the middle to upper ordovician. It was probably around 50 feet down. All I have is the tail. Probably not enough to identify, but any information would be appreciated. I couldn't find a measuring device, but I will post a picture with one as soon as I do. It is about 8 1/2 inches long, or 26 1/2 centimeters. Map is upside down. I have the fossil on hand for any clarification/questions.

    Large ordovician tooth?

    First off, I don't know anything about paleontology. I found this fossil in Nicholas county Kentucky. It was about at the C in NiCholas county on the map. Sorry it's upside down, but Nicholas is 2 above bracken, assuming picture orientation. The fossil was 6-10 feet down. The first layer of fossils went down about 5 feet, maybe more, and we're tan and sandy. Below this layer was a gray layer, and this was several feet into that. Also, don't have enough file space to do enough pictures for inches, but it is about 11.5 centimeters long, or 4.53 inches.
