    Edestus teeth

    From the album: Sharks and fish

    The shark relative is genus of eugenodontia holocephalid from the Carboniferous-Pennsylvanian age Anna shale formation, Carbondale group, found in different Illinois coal mines. I dont know(yet)which mine these were found in. This unidentified species is of the "vorax-serratus- crenulatus-heinrichi" or "E. heinrichi group", with the teeth being more of a standard triangular shape, as opposed to being thinner and pointed at a forward angle as in the "E. minor" group http://www.thefossilforum.com/applications/core/interface/file/attachment.php?id=50175

  6. Hello, I have been a long time member of the fossil forum, but I have never posted before. I live in south Florida and I am planning on making a trip up to northwestern Georgia, northeastern Alabama, and southeastern Tennessee for two or three days and I was wondering if anyone had any suggestions on fossil hunting sites in the region. Any recommendations would be greatly appreciated.

  8. I found these fossils beneath a steel rail bridge in Maryland near the 4 locks of the C & O. You can find it. I think they may be Silurian, and are mostly brachiopods, including an adult brachiopod. Observe the fleshy muscle material in the center. Observe the 3 parasite wormy animals at the upper left. I think this was an old Brachiopod near death: It was infected with wormy parasites. Its muscle flesh was infected with a fungus that brought in sulfur in to react with the Iron in the water, creating pyrite which is yellow in the fossil.
  9. There is a website that describes a controversial fossil found in 2003: http://www.abc.net.au/science/articles/2003/11/10/984724.htm Since it doesn't have a name at the time of publishing, I'm finding it difficult to find more information on it.

    Triarthrus finds

    Hello again! This post will be about some beautifully preserved Triarthrus fossils (and my first complete Trilobite finds). Some of them even have the eyes preserved! I found these at a local train station, and the site of significant construction lately. I believe most of the to be E. eotoni, and the last one to be E. rougensis or spinosus. It may not be visible in the picture, but the last one has a streak of pyrite along the side of its cephalon / upper thorax. Could this be some kind of soft body tissue preservation, similar to those of the Beecher's Trilobite bed?

    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. My family decided to take a few day trips to Delaware’s beaches this summer. We went to a few, and heeding some posts by @I_gotta_rock, I kept an eye out for fossils. I found a few, but three were good enough to show. No one knows which formation exactly they come from, only that they are Paleozoic. Sounds like a good Thesis to me. Anyway here we are, first a worn coral bit, kinda like a petosky stone. .7 inches

    Isotelus

    I found this last month on a visit to an abandoned limestone quarry near Naponee, Ontario. Though I am not very familiar with the Trilobites of this area, I believe it's an Isotelus. If I'm wrong with this identification, please tell me. It looks like there could be more of it underneath the sediment, and there is some matrix covering the pleura. This limestone is flaky and darker than any I have seen before. How would I go about prepping this? Though I've heard many people use sand, should I use something less abrasive, like baking soda? Thanks for the help.

    Fossil ID

    This may or may not actually be a fossil. It is a cylindrical, shimmering white streak on the Shale. It is only about an inch long. This may just be another mineral inclusion, or some discoloured sediment. Any help with identifying this would be appreciated!

  21. Hello TFF members! I have just found several strange circular rocks on a fossil hunt a few minutes ago, which I believe to be either nodules or concretions. What should I do to split these rocks? I know that I should probably not try to break them with a hammer and chisel, and instead use the freeze-thaw process. This is my first experience with nodules or concretions, so I am not very knowledgeable on this topic. Is there a specific recommended length of time I should leave them in the cold? How long should I thaw them for? How many times should I put them through the process before seeing cr

    Agnostid?

    I found this fossil a few days ago at an exposure of the Billings Shale. It was found associated with Triarthrus glabellas and brachiopods. It's structure leads me to believe that it's either an Isotelus pygidium or an agnostid, although I do not know of any agnostics described in this formation and age.

    Anthology Of Unidentified Fossils

    Hi again! This will probably be my last ID post for a while. This time, I've decided to put all of the Unidentified fossils in one post. These are all from the Ordovician aged Billings Shale. Help identifying these will be much appreciated! 1. Leaf-shaped imprint. Mineral inclusion? 2. Trilobite fragment? 3. Dark markings and furrows. Burrows?
  24. Hello TTF! This post will contain the pictures of my science fair board, as well as the awards I received from it. Sorry for the delay, I know that some members posted requests for these months ago, but I have been busy with other things lately. I actually left part of the board at school by accident for weeks. I hope the pictures are clear enough!

    Repairing Fossils In Shale

    Recently, I have been out fossil hunting more often than usual, and many of them have since been damaged. Some were broken during transportation, and others were broken as I excavated them. The fossils are all from the black Billings Shale, which fractures easily. Is there any way that I can repair them without leaving any obvious markings?
