  1. Conulariid

    I found this conulariid in a stormbed of the Utica Shale. I am not very familiar with conulariids, and was wondering if a more specific ID was possible. Unfortunately because of how the rock broke I was unable to recover the rest of the fossil.
  2. problematica/incertae sedis from Europe

    THES about 10 MB generally quoted as being "unpublished" Fredrik Jerre: Silurian Conulariids from the Visby Beds,Gotland Examensarbeten I Geologi vid Lunds Univeristet,1988/n.25 recommended
  3. I'm happy to report that the fossil Gods were kind. This is only my second trilobite hunt ever, and I found a gem. I also found some other things, some I know, some I don't. First I'll post the ones I know. I'm posting this in "Fossil ID" and not "Trip reports", because I have more questions than answers. A nice bit of Conulariid that goes through the matrix. I still need to finish the prep. Cephalopod Bivalve, gastropods, cephalopod A nice hash plate. Now down to my mystery items. These are all from the Ordovician period. Unknown Brachiopod #1 Big mystery item (eurypterid material???) #2 Big mystery item (this has the exoskeleton look of a trilobite) I was thinking a single lateral pleural from a very large trilobite.

    Conulariid - - Shadow Lake Formation, Kingston, Ontario

  5. Fossils of the Gull River Formation, Black River Group This past weekend I came across a newly excavated site here in Kingston, Ontario. After spending a few hours over a few days here is what I collected. Cephelopod - Gull River Formation of the Black River Group, Kingston, Ontario 4.75" x (0.5" to 0.3") Conulariid - 0.75" x 0.5" - Gull River Formation of the Black River Group, Kingston, Ontario Thank you to Peter Lee and Nathan Thomas for identifying this for me. (Daimanella) - Brachiopod - Gull River Formation of the Black River Group, Kingston, Ontario 1.2" x 0.75" (Ceraurus Cephalon) Trilobite - Gull River Formation of the Black River Group, Kingston, Ontario 1" x 0.75" (Species Unidentifed Yet) Trilobite - Gull River Formation of the Black River Group, Kingston, Ontario 0.25" x 0.125" Collected several other specimens that I have not photographed. One in particular, an isotelus pygidium, that I still need to photograph. I'm always wanting to make sure I have the right species names. If you know of an error please let me know. I have been learning a lot from everyone on this forum. THANK YOU
  6. Conulariid From Permian...

    I found these yesterday in what I could possibly make out to be a similar bedding plane (if that is the right term). I was wondering if anyone might be able to help me identify what species it is? It is from the Permian found on the South Coast on NSW Australia.
  7. These are a few of the pdf files (and a few Microsoft Word documents) that I've accumulated in my web browsing. MOST of these are hyperlinked to their source. If you want one that is not hyperlinked or if the link isn't working, e-mail me at joegallo1954@gmail.com and I'll be happy to send it to you.
