  1. Hi I was wondering if anyone could help me identify some of the key anatomical features of the calyx of this crinoid (Apiocrinites elegans) and any anatomical features of this brachiopod (specimen unknown). I have trawled and searched but am having limited success so thought there might be a fair few people that would be able to lend a helping hand on here! cheers mark
  2. Mosasaur skull cast

    Hello evereybody, I dont know if this is the right place to post this but I would be interested to learn more about mosasaur skull three-dimensional anatomy. Do someone know where it is possible to buy accurate mosasaur's skull cast? I am looking for something more educational than decorative and ideally not too big. I know that there are plenty of interesting stuffs on the web but from my experience in human medecine nothing is as good as a three-dimentional model to understand complex anatomical structure like the skull. Thanks for helping!
  3. New detail of internal structure of trilobite eyes and implications of their location on the tree of life. https://www.nature.com/articles/s41467-019-10459-8
  4. Hi all, Need a little help identifying this bone from Bracklesham, UK. It measures about 1 inch long, should be Eocene age. Thanks in advance. Jay

  7. Borg!

    Folke Borg On the body wall of Bryozoa Journal of Cell Science/1926/s2-70 *TAKES a deep BOW* very little of this great bryozoologist can be found online.

  9. This was a really cool museum. I especially liked their selection of fish and marine reptiles. They also sported a largely complete tyrannosaurus skeleton, an Ammonite five feet tall and four feet wide, and a large completely intact mammoth. Pelagosaurus Typus A Mary Anning Icthyosaur (Two more were present) Plesiosaur Eryops A large fish (One of the Many on display) A perfectly preserved Crinoid The nicest ammonite (My opinion) Perfect spiral pattern And much more that we didn't get photos of........
  10. Mysterious stripes on Echies

    I've always wondered what the 5 radial stripes on echinoids we're and what they do. Any urchin/sand dollar experts know? Polished Echie with the "stripes".

  14. Hi all! Under the presumption these are echinoderm I've been searching for anatomical features, particularly disarticulated crinoid and archaeocidaris of which both are plentiful in the matrix. In my searching I've been unable to find anything that even remotely resembles these pieces. Any input is much appreciated. Plattsburg fm. - Hickory Creek sh. I attached a group photo of some of them I found, followed by 4 select specimens showing each side front and back. For scale, field of view is ~1cm. Group shot Front Back Front Back Front Back Front Back Thank you all!

    From 1895,and in German,but hey,oak leaves (recent and fossil) never looked better than in this monograph vonEttingshausen
  22. dictionary of invertebrate zoology

    This might be useful. Is it complete,is it any good? if you stumble acros that one annoying term that keeps you from reading further.... Does anyone know of something comparable,BTW? http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1001&context=onlinedictinvertzoology EDIT: ok did a little test anderidia:not in there synapticulotheca: not in there Do I know these words? Yes,i do,and probably everybody else here interested in brachs or corals come to think of it:anderidia mayby just in fossil brachiopoda? Maybe i'm being too harsh edit two: matrotrophy: not in there
  23. big bird

    Structures like these are inherently interesting... Na& Pern 2014 cassohibilogy, evolution.pdf
