  1. Hi! My name is Alexandra. I live in St. Petersburg, looking for and preparing trilobites. As you know, we have near St. Petersburg very good places to search for fossils known all over the world. If someone from trilobite lovers wants to come and find good specimens here or if you are traveling through Russia and you will be interested to come in search of trilobites, then I can easily show you the best places to search near St. Petersburg without problems. You do not need anything for this-it will be absolutely free for you. I can explain it by the fact that I am the same person as you, and I have the same disease that can be called "paleontology" Is this interesting for you, write to this topic or search for me in Skype: Alexandra Kalinina (with bird on skateboard on avatar :-) ) and ask any questions. P.S. sorry for my English
  2. Admin please move to appropriate topic if needed. :-) Fillmore County, Minnesota, USA - the most fossiliferous county in Minnesota Ordovician Mostly Galena Formation Whispering Winds, Spring Valley, MN I thought I would share some pics of my fossil barn that I have been remodeling on a budget. There are some ideas here that others may be able to make use of. :-) Overview of the outside of the barn. Note the trilobite cutout an pterodactyl toy at the peak. Galena Formation large cephalopod. The hitching rail is nice to use as a comparison to the approximate size this orthocone ceph may have been. The kids love this dinosaur island in the old wooden watering tank. I give fossil tours and host fossil birthday parties. :-) The fossil prep table is open to guests. I have a grinder and brush, a couple of engravers ($7 from Harbor Freight), a dremel tool, and $5 3 magnification visors. Lori turned me onto a mini microscope for less than $5 off Amazon. I also make wire wrapped fossil jewelry here. This wall was created using pallet boards that were stained or washed with paint. Everything is pieced together like a puzzle. I had a couple of gals here wwoofing (wwoofusa.org), trading time for experience and room and board, and they loved doing this creative work. They also put up the reclaimed tin ceiling and I put different reclaimed tin down as wainscote. Note between the 2nd and 3rd window the dried mushrooms being used as shelves and decorations. I'm wanting to add shelves in the windows at the pane lines for more fossil display and greyed wood shelves supported by rusted chain, eventually. I had some 1880s cedar shingles and put them up on two of the walls around some pallet shelving. The pallets are super sturdy shelving for fossils and FREE! Some more pallet shelving and I used some cut off ends for a few papers. I keep my gear in the barn also. Sometimes I use it as a woodworking shop. I like to work in live edge cedar. Kids and adults all enjoy this old aquarium with a black light in the hood as a fluorescent fossil display. I have rock and minerals in it as well. The walk-in door to the hen house is in the fossil barn, I also raise white homing pigeons and ducks. So this pterodactyl is a lead in to the descendants of the dinosaurs. :-) Now to the gardens...
  3. ID please - Ordovician - Edrioasteroid?

    Hello. I'm attaching two photos: #1) an image of a "Rare Primitive Echinoderm (Edrioasteroid) from the Upper Ordovician of Ontario, Canada," from the following fossil website: https://www.fossils-uk.com/product/new-rare-primitive-echinoderm-edrioasteroid-from-the-upper-ordovician-of-ontario-canada-sku0918-isorophuella-incondita/ #2) a fossil that I found that looks similar and is about the same size as the Edrioasteroid from #1. Is it possible that my specimen (#2) is this Edrioasteroid? Thanks for any assistance! Camille
  4. Hello. The attached photo shows two rocks found in Toronto, Southern Ontario, Canada, at Mimico Creek. I juxtaposed the two because it seemed to my amateur eyes that the one on the left might have some similarity in structure to the two "mallet-shaped" structures in the rock to the right. Any help in ID'ing these would be greatly appreciated. Camille
  5. Graptolite or New Species?

    SE Minnesota, USA Ordovician Galena Formation I'm sorry I do not have a better pic but it went home with the guy who found it. I just hosted a Father's Day hunt and this was found. I would say graptolites but NO SAWTOOTH EDGES! It did not, in the field, to me appear to be crinoid. I have honestly not seen anything like it before. Maybe it is just how it fossilized, but this was a wow to me! He was pretty thrilled! I would be too! :-D Thoughts anyone?
  6. Anyone recognize this?

    Any recognize this? I have come across a few of these recently in the Lebanon limestone in middle TN, mid/late ordovician. Most have been much smaller. This one still has a thin layer of matrix over much of the surface (with a fragment of a graptolite), but it's the only one I have a photo of. Thanks
  7. Let's talk brachiopods!

    Hi all, I don't know much about brachiopods beyond general recognition. Since I found that little unidentified echinoid(?) I have decided to prep some of the loose brachs that I found on a recent trip to Fillmore Co., MN. The complete brachiopod here appears to have been attached to another brachiopod shell. So here are my questions. 1. Can anyone identify the brachiopod? (I am assuming they are the same species) 2. Would this be considered an unarticulated brachiopod? 3. I haven't finished prepping the interior of partial brachiopod. I wasn't sure what to call it so I referred to it as the host shell in the photo. It has what almost looks like an open crack. Any idea what might have caused this? There are little black specs surrounding it. Could this have been caused by another brach pedicle? When I was prepping it, it kind of reminded me of a burrow lined with tiny fecal pellets - but my imagination does tend to get the best of me. As always, thanks for your help! @minnbuckeye @Bev @Tidgy's Dad
  8. Worth prepping?

    Found this the other day. both look inverted. Is this worth having a professional prep? Thank you.
  9. Trilobite Watercolor

    My family and I went on a cruise in December and my 10 year old dragged me to the watercolor painting lessons during the "at-sea" days. I got hooked on painting, she didn't...Anyway, these are my first attempts at combining two of my hobbies.

  11. Ordovician Road Cut

    Yesterday, I was lucky enough to attend a very special field trip with the Eastern Ontario Natural History Society to a massive road cut in Ontario. The rock exposed was Ordovician aged limestone, and it produced some amazing fossils. I might need some id help with some of these. The giant cephalopod was by far the best thing I found! 1. Giant Cephalopod (with hand for scale) Camerocerad or Endoceras? 2. Crinoid stems, bryozoans and Gastropod 3. Partial trilobite pygidia
  12. Ordovician - Southern Ontario - ID please?

    Hello. I found this in Mimico Creek in Toronto, Ontario. Could someone please tell me what it might be? I thought maybe some kind of cephalopod, but really have no idea. Thanks! Camille
  13. Hello Everyone Today my dad and I visited Bullengarook slate quarry to hunt for some graptolites. The site is aged middle Ordovician and was originally used for slate and gold mining in the 1800s I believe. There was many mine shafts still present and accessible at the site but I decided not to explore them. (Too creepy!). We arrived at the site at 1:00pm and spent the next three hours digging into the spoil heaps and splitting rocks. We came out with many beautiful examples of graptolites. Unlike Bendigo which has red graptolites, the graptolites at Bullengarook were the typical white carbon colour. Hope everyone enjoyed, Daniel
  14. Tetragraptus serra Brongniart, 1828

    Graptolite collected from Spring Gully, Bendigo, Victoria.
  15. Graptolite collected from Spring Gully, Bendigo, Victoria. I believe it is T. fructicosus but would appreciate a second opinion.
  16. Phyllograptus typus?, Hall 1858

    Graptolite collected from Spring Gully, Bendigo, Victoria. Believe it is P. Typhus but not sure. P. anna maybe?
  17. Managed to get out to a site I haven’t been to before, and found lots of cephalopods and gastropods. I recently got back into geocaching (my husband and I used to geocache as students about 10 years ago, back when you had to use a handheld gps unit. Now you can just use a smartphone.) Anyways, we didn’t collect at this location, since the geocache makes it an excellent learning resource for people who don’t know much about fossils. A few photos attached.
  18. I made two trips to Little Falls NY recently, one alone, and one with my 10 year old that I took to Penn-Dixie last year. Both trips were successful. The fossils are abundant, relatively easy to find and extract, and the site is kid-friendly. It is slippery on the slimy shale in the water, so be careful. The shale can be sharp and cuts fingers easily if you use ungloved hands to brush bits away from a site you are excavating. The shale is also very oily, can will stain fingernails, so consider gloves with covered fingers. Rare pyritized fossils can be found. I also found two cephalopods.
  19. Brachiopod Star Tattoo?

    While scanning some of the fossil plates I found hunting with @Bev and @minnbuckeye, I noticed this little star-shaped discoloration on one of the brachiopods. Anyone have any idea what could have produced this mark?
  20. H. carens

    From the album Trilobites

    Hydrocephalus carens (Barrande, 1846) Cambrian Jince Fm Skryje, Czech Republic This was a gift from a fossil comrade who collected there.
  21. I was out hunting near Spring Valley, Minnesota with @Bev and @minnbuckeye the last couple of days. As always, I was looking for coprolites. Mike came across this first piece, sitting loose in a piece of weathered matrix. While we were splitting rocks, we found a virgin layer of the source matrix. When we got back to Bev's fossil barn (everyone should have one), I took a peak under the microscope at two of the loose, irregular objects but couldn't really see much because of the powdery iron oxide coating. When I lightly rinsed them, they revealed these microscopic (calcareous) jack-shaped objects. Similar inclusions were in both objects loose objects. You can see from the broken spine on the inclusion in the lower right that they are hollow. In the other loose piece and those still embedded in the matrix, I can also see random straw-like spines of the same material. I'm not sure if these are coprolites, algal masses or something else. I have seen coprolites covered in powdery iron oxide before. Eventually I would like to free more of these from the matrix so that I can sacrifice one to get a look at the interior. Can anyone identify the little jack-shaped inclusions? The spines may have been quite a bit longer. The only things I can think of are forams or perhaps diatoms. Bev and Mike - What was the name of that cliff again? Decorah Shale? @Carl
  22. Ohioan Oddities

    Whenever I find a new fossil, I usually put effort into identifying it. Usually, I can turn off my computer with a label for the fossil, and I'll go to bed happy with the new item on my display shelf. However, these guys have always been at the back of my mind for years, and it really nags at me when I have to explain what they are to someone else. Not anymore, I guess! ----------------------------- These were found in the Liberty Formation of the well-known St. Leon roadcut in Indiana. I am thinking they are some kind of internal clam mold, but consider it very unlikely due to an inwards impression that is identical in both fossils.
  23. Unknown Finnish fossil

    A few weeks ago I was on my very first fossil hunts. With some beginners luck I managed to find a few trilobites and orthoceras but I also found a very peculiar fossil that I am very curious to learn more about. The place where I found it is called the Aland Islands and is located in the Baltic sea between Sweden and Finland. Ive read that the fossils in this area comes from either the Ordovician or Cambrian ages but I am clueless on which age the stone comes from that containes this fossil. It appears to be complete only missing one "eye" on the half that is exposed. On the negative I can clearly see the "eye" imprinted. The shell/skin is extremely fragile and crumbles if touched and most of the shell/skin is stuck in the negative. When I turn it upside down I can see that the fossil is symetrical with half still in stone and other half exposed. It is approx 7 cm long, 4 cm wide and 2,5 cm high. Anybody got any ideas what this might be? Ive searched thousands of pictures in this forum and on the internet but nothing even comes close.
  24. Three Ordovician Uncertainties

    I have a hunch about these, but I felt it best to get some more seasoned input. The first two are trilobite partials. I'm tempted to call the one on the right just another small Isotelus, but the segmentation doesn't appear quite right. Found in the Lindsay Fm. The second image is a matter of dispute (or so I was told) with one expert stating it is an ammonoid, and another stating it is a gastropod. Found in the Whitby shale. About 5 cm in diameter.
  25. Just seeking to verify whether or not this is a Leviceraurus mammiloides or just plain Ceraurus sp. Found yesterday in the Lindsay Fm (Ordovician) in Ontario. If the former, it is sadly missing the long pygidial spines. Prepping this one is a bit of a challenge as it is fragile in places, and the matrix is very stubborn (I may have to get someone else to fix this one). I've done what I could with abrasion. Specimen is very small: 1.5 cm. For comparison, the specimen and the line illustration from Hessin's book. The genal spines don't look quite long enough to be a Levi, but the spine appears broken off before the termination point.
