  1. Teilhardina revised

    A new paper regarding primitive fossil primates is available if you're interested: Paul E. Morse; Stephen G.B. Chester; Doug M. Boyer; Thierry Smith; Richard Smith; Paul Gigase; Jonathan I. Bloch (2018). New fossils, systematics, and biogeography of the oldest known crown primate Teilhardina from the earliest Eocene of Asia, Europe, and North America. Journal of Human Evolution. in press. doi:10.1016/j.jhevol.2018.08.005. Ni et al. (2004) were the first primate workers to propose that Teilhardina is polyphyletic, but Morse et al. (2018) formalize this scheme by erecting Bownomomys for two nominal Teilhardina species from North America. I just wanted to ask for a copy of this paper because it is not accessible at the Journal of Human Evolution website.
  2. Triarthrus eatoni

  8. Unknown Skull ID help

    Hello everyone, new member here! We recently started boxing up my childhood home to ready it for a sale and I discovered a long forgotten box that had a few fossils that my grandmother obtained during her ongoing 91 years on this earth. Almost all I believe were obtained by digs she went on around North America and chances are she obtained this one in the midwest. Most had tags like fish, mammoth tusk shard, and part of a deer jaw. I couldn't find an ID for this one, and upon asking my grandmother she hasn't the faintest idea because it's been decades and her mental state is slipping. If you need any more pictures of any sides let me know, my hand is only there to hold the two halves together, because unfortunately it hasn't survived in one whole piece. It measures about 160 mm. Another clue, but she did majority of her digs in Nebraska I believe. I'll have to Split up my posts with the pictures, I apologize.

  10. Brachiopods and Bivalves

    Hi all As I age, I am working on talks and the co-responding displays to donate my collections to be used while I can for talks to curious people who come to the natural history society where I volunteer. After i'm gone, having written out the talk and picture power point and with the actual fossils, these talks could go on. Also hopefully made available to teachers. Anyway, I am struggling with finding an intriguing story lines for a talk on Brachiopods and Bivalves. For example in my cephalopod talk, the story line is how they overcame the problem of buoyancy. So i am asking for your thoughts for something similar on this topic. Also ask for your recommendations for specimens to include. I'm looking for ones that grab people's attention for beauty, ugliness etc. I have id'ed: spirifers (pyritized), lamp shells, Ruck's pit Mercenaria, Cucullaea (Giant clam), Panopea, Cretaceous oyster Exogyra, Inoceramus, Spondylus, Arca hinge teeth and markings. There are some weirdly beautiful rudists from Texas (would anyone be willing to donate to the cause?) Hopefully this gives you some idea what I am trying to do-specimens that each have their own special story to catch people curiosity and interest to promote their interest in learning. And if possible, an overarching story line that unites brachiopods or unites bivalves. Appreciate everyone's thought and comments. Thanks
  11. A Fossilized Thing

    Hi again! I’m totally stumped with this one. The rock is limestone, so its not the Billings formation. There is still some matrix on it, but most of the surface is exposed. It’s spherical and slightly faceted. Fossil pearl?
  12. 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?
  13. 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!
  14. 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
  15. Splitting Nodules And Concretions

    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 cracks? How cold should the environment be for the freezing to work? If they are in fact nodules or concretions, I will post pictures of my finds (or lack thereof)!
  16. 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.
  17. 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?
  18. 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!
  19. 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?
  20. NALMA, SALMA, GABI

    FLYKOwswish this article has some bearing on the following issues: Mammal biochronology,the precise timing and/or speed of the G(reat)A(merican)B(iotic)I(nterchange),it contains some remarks on mammal taxa(however brief), magnetostratigraphic resolution from the Miocene to the Pleistocene, the closing of the Panama isthmus, and the possible diachroneity of mammal taxon appearances. There are NO taxa illustrated,and the authors' (infrequent)use of "heterochroneity " is unfortunate . If you have Woodburne(2012): this might be up your alley I liked it,but I'm weird that way
  21. Triarthrus?

    Hi TFF! I have just found a very interesting fossil near my home which I suspect might be the articulated left and right pleura of a Triarthrus. I have already found other fragments of Triarthrus in the same rock outcrop. (Glabellas, pleura, cephalons, etc.) It may also be a graptolite or something similar.
  22. Orthocone or Hyolithid?

    Another fossil for ID! This time, I think that I have some possible orthocone nautiloids from the Billings Shale. I found these near a small construction site near my house. Although I suspect them to be cephalopods, they may also be Hylothids. Or, they could be something else entirely! I am not an expert on these faunas at the moment, so I may be wrong. Each photo is of a different specimen. Thanks in advance! More posts about the regional science fair are to follow.
  23. Dear TFF members, As some of you may already know, I have been working on my science fair project concerning the Trilobite Pseudogygites latimarginatus for several months. This science fair project has been awarded a position in the Ottawa Regional Science Fair held at Carleton University this week. Your help has been instrumental in my success, and my appreciation cannot be expressed in words. As one way of thanking you all, I am inviting anyone on the forum who will be in or near Ottawa at the time to attend the fair. My project will be open to the public this Friday, April 6th, from 2:00 pm - 4:00 pm, and again this Saturday, April 7th, from 9:00 am - 11:30 am. It is titled, "The Impact of Environment on the Biodiversity of Pseudogygites latimarginatus." My project's number is 1101. I will also have some of my most prized fossils on display, as well as some edible specimens, for the Trilobite enthusiasts! I am not asking for anyone to go out of their way to see my project, this is just a simple invitation. Everyone is welcome.

  25. Hello again TTF! This will be my second post about my finds from my first trip to the peace river! This post is dedicated to one of my favourite finds and one of my favourite animals, the mammoth! During my trip to the peace river, I found many beautiful fossils myself, but I seemed to have had the best luck searching through other people's garbage. The location where I went to collect in was already visited many times by other people. Everything unwanted that turns up in their shifters is usually thrown to the banks, creating garbage piles. One particularly productive garbage pile produced many of my favourite Dugong ribs, my only meg (more on that later) and a mammoth tooth! How someone could look at these things and throw them away is beyond me. Unfortunately, the tooth was already fragmented when I found it. I believe that all the fragments came from the same tooth, though, because some fit together perfectly! I also have a question about this tooth. Is it possible to identify the species of mammoth from the tooth, either from its features or by looking at the known species of mammoth present in Florida? Thanks!
