  1. I recently found a nice Calymene tuberculata trilobite on my vacation to Gotland. I’m currently in the process of preparing it and wonder what coating I should use? Is it possible to give it a slightly wet look while not making it look glossy and artificial? I’m considering some kind of vax-based product. Any tips?
  2. Hey, all! I have a surplus of Upper Ordovician (Cincinnattian series) and Silurian fossils from the Dayton area. Fossils include diverse brachiopods, horn corals, orthoconic nautiloids, and bryozoans as well as trilobite fragments. Would anyone like to trade for these fossils? If there's anything in particular that you'd like from the area that I don't already have in my collection, then I may be able to go search for it before the trade, too. If anyone expresses interest, then I'll upload images of said fossils in the next few days. Let me know!
  3. Paleofavosites asper

    From the album Hamilton, Ontario Fossils

    Paleofavosites asper (d’Orbigny, 1850). Coral squashed on grey shale. Found in the Manitoulin Formation of the Cataract Group on the Niagara Escarpment. Locality is the Devil’s Punchbowl, Stoney Creek, Hamilton, Ontario. Early Silurian.
  4. I made a trip today to Albion Falls in Hamilton, Ontario, Canada by public transportation. Albion Falls is a classical waterfall that cascades over the Niagara Escarpment in Hamilton, Ontario and is 19 metres high. The waters flow north along the Redhill Valley as Redhill Creek to empty to Lake Ontario. Once a popular tourist destination, climbing up the waterfall is not allowed anymore due to paramedics having to rescue irresponsible tourists who have hurt and died from slipping and falling. I mostly ended up checking out the Grimsby Formation which is nicely exposed near the waterfall. There are walls of exposure as the water meanders down from the falls, revealing nice explorable spots. The Grimsby Formation is part of the Cataract Group and dates to the early Silurian period. The Grimsby Formation is not popular as it is not fossiliferous. I’ve had better luck finding fossil animals in the Manitoulin and Cabot Head Formations at the Devil’s Punchbowl in Hamilton, Ontario. The reddish maroon bottom part of the exposure is the Grimsby Formation. It is mostly red/purple shale mixed with the same coloured sandstones. Here is a pic showing how the Cabot Head Formation of the Cataract Group progresses into the Grimsby Formation.
  5. Pentameroides subrectus

    From the album Hamilton, Ontario Fossils

    Pentameroides subrectus (Hall and Clarke, 1892). Found on a road cut along the Niagara Escarpment in Hamilton, Ontario, Canada. Reynales Formation, Clinton Group. Silurian, Llandovery epoch, Telychian age. Size is approximately 10 cm across.
  6. Fossils in Wren's Nest

    Hi. I visited Wren's Nest, Dudley, UK last summer. Just wonder if the fossils shown in the photos were corals or sponges. They were not uncommon but both were possibly damaged by diggers who attempted to excavate them. My apology the subject was a bit out of focus. Thanks. KS
  7. Is this a fossil?

    I have seen slabs of this kind of stone where I collect my fossils. Yesterday, I found a piece with a leaf impression and was wondering if this is an "old" rock and if the leaf impression is a fossil. (I do ask around and search online, but I get stuck often. Thx)
  8. 2 questions

    I was wondering if the lower left white pieces with the straight row of circles are bryozoa. Secondly, I was wondering if the seemingly silver "rod" is animal or mineral. These samples are quite small and this is the best I can do as far as focus goes.
  9. Unusual Waldron Shale Object?

    Found this interesting object in the Waldron Shale (Silurian) at a site in Vernon, Indiana. The object is just over three quarters of an inch long. I'm not familiar with the Waldron Shale. The site also produced a wide variety of organisms- brachiopods, gastropods, trilobites, crinoid stems, and a bryozoan. Any help you could provide with the ID would be greatly appreciated. I apologize for the quality of the photographs.
  10. brachiopod or piece of coral?

    Can you tell from this shot if it's a brachiopod or a piece of coral sporting that gpod design? Thx!
  11. Is this a crinoid stem?

    Is this sample a crinoid?
  12. Help with ID

    This sample is 2 cm. I was wondering what I'm looking at. Thx.
  13. Unknown Silurian Fossil

    Hi guys!!! Going through material from our last trip and wondering if anyone can help ID this? Assuming fossil and not mineral... If you look closely there are smaller segments of it around the obvious area in question. As always, any feedback appreciated!
  14. Hello, in the Silurian rocks I found during my last trip to the Balic Sea, I found a few strange things. The first one is 1,5 cm long, 0,6 cm wide: This is the best magnification I can get - sorry for the flash reflection in the magnifying glass. The other one is bigger - it's 3 cm long and 1,5 cm wide These first two emerged after splitting the rock. The last one is on the surface - it's 4 cm long, 1 cm wide. You can feel the little grooves. Is it something ot just a rock scratched in an interesting way?
  15. It was a planned family get together at my sister's ranch in Kentucky to celebrate my father's 90th birthday. I was travelling from Southeastern New York by car. Made it to Harrison, Ohio the first day, right on the border with Indiana. Next morning, weather was pleasant and I was out to the famous St. Leon road cut, a place that I've wanted to visit for years. Finally made it there. Spent the entire day. Despite the site's fame, didn't see another collector and except for one brief shower the weather was perfect though a little on the warm side. I explored the entire exposure though the best was just below one of the terraces where the brachiopods and corals were weathering out of the shale complete.
  16. This weekend I went again to the Baltic Sea coast. This time my target were Miocene deposits of lignite in the cliffs around Chłapowo. This is one of the cliffs I climbed in vain: because the only thing I found has nothing to do with Miocene - it is a piece of a crinoid stem, so most probably Silurian.
  17. Just found this juvenile Eurypterid a couple hours ago....went rubble picking today in the Silurian waterlimes. I got very lucky....like 1 in 10 years of searching lucky. Time to get some lottery tickets! All kidding aside....I’m floored....super happy. I’ve been trying to find a nice Eurypterid for years ever since my first hunt in 2010-11. It’s about 1.5 inches. Juvenile for sure. It has walking legs and the swimming paddle on the left side. The right walking legs and paddle could be present but I’m too afraid to touch it. Here is a raw shot from the field. After a cleaning and application of a thin thin layer of washable Elmer’s glue and water to make it pop more. Picture with a scale. I also found this quality prosoma. I did find 2 other partial prosomas, body segments, a telson (mostly covered), a mouth plate with nice teeth, and I took home a few chucks of the Phelps member to freeze thaw. Never know right?! All my finds are in rubble so I might as well bring some rubble home haha. That’s all, just really excited..... Al
  18. Halysites (?) specimen

    I found this pretty little chain coral in southwest Michigan glacial drift a couple of days ago. I'm interested in whether it's possible to narrow the ID down between a Halysites species or another genus, like Quepora. My simplistic understanding is that coenenchymal tubules would indicate a Halysites species, so that's what I've been focusing on, although I know there are many other indicators, like size and shape of corallites. size of ranks, shape of luminae, structure of longitudinal tabulae, etc. This piece is probably too silicified to tell without thin sections, anyway, but I thought I'd throw the pics up, in case there's a coral person here who can help me interpret any diagnostic features they see. (The tape measure I tried to hold up in the last photo is cm) Many thanks!
  19. 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?
  20. Lepidocoleus sarlei

  21. Lumen cast?

    Is this a lumen cast of a crinoid column? Secondly, is it geodized?
  22. Brantford, Ontario Geology??

    Hey guys, So I discovered there is actually GO transit service from Hamilton, Ontario to Brantford, Ontario and Im actually excited to discover this (HOORAY!!). Does anyone know the geology of the city? Im also looking for papers/files that can help me know what to find there. Thanks for any help!
  23. Beekite rings

    Do I see beekites on my coral sample?
  24. Clark Co Indiana Road Cuts

    Hello All, Was wondering if anyone knew of Silurian and/or Devonian road cuts in Clark Co., Indiana, or not too far in surrounding counties? I am hoping to attend the Falls of the Ohio Symposium on June 22, coming in from near St. Louis on the 21st. We do not have a lot of Silurian or Devonian sites, so would like to collect some specimens. Would be happy to meet any TFF member if anyone is interested in checking out those road cuts. Thanks, ODK
  25. Brachiopod

    Is this an atrypa? What part of the anatomy am I looking at?
