  1. Hi guys! I found the attached Silurian and Devonian fish online and would appreciate your opinions on the specimens. The first is a Galeaspid, Polybranchiaspis, from Yunnan, China (43mm in size) and the second is an Osteostracan, Tremataspis schmidti, from the Rootsikula Formation, Island of Oesel, Estonia (28mm and 16mm headshields). They are dated to the Upper Silurian and Lower Devonian respectively. From some research it looks like the Tremataspis is genuine, however I’m not 100% on the Polybranchiaspis. Any input in terms of their authenticity would be greatly app

    Book Request

    Hi everyone! I am looking for a pdf of a book, "Agnatha" II (Thelodonti). Handbook of Paleoichthyology, volume 1B. It is very expensive, and I was wondering if any of you had access to it. Thanks in advance!

    Theropod footprint?

    Found this fossil in my grandads old collection, so unfortunately I have no info on where it’s from. Any help with ID would be much appreciated! I thought maybe it was grallator or a Devonian fish? Some more images in the comments

    an Ordovician impact in the usa

    JGSL The Winneshiek biota: exceptionally well-preserved fossils in a Middle Ordovician impact crater Derek E.G. Briggs, Huaibao P. Liu, Robert M. McKay and Brian J. Witzke Journal of the Geological Society, 175, 865-874, 24 September 2018, https://doi.org/10.1144/jgs2018-101 Cannot recommend this one highly enough size:about 8,5 MB Note:the Ames impact straddles the Arbuckle/Simpson Boundary
  5. Apart from a little gem by Belles-Isles (1987,Neues Jb/Abh,etc) gem, no studies were ever done on pteraspid swimming. Not visually over exuberant,but a VERY GOOD study, I believe. About 300 Kb, and from a while back, too. kermack23.full.pdf
  6. 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. Please note that this list will be updated continuously as I find more available resources. All of these files are freely available on the Internet so there should be no copyright issues.
