Dog skeleton

Discussion in 'Skulls and Skeletons' started by Jean-Christophe, Jul 26, 2015.

  1. I cleaned and assembled a full dog skeleton. The mount is done inspiring a lot of the old mounts we have here in the Museum of Natural History in Paris, so using pretty much only wire, no glue to assemble and hold everything in position. I have to admit that I used some glue for small sesamoid bones and to add strength in feet but it wasn't a need.
    I like the look of these specimens, plus they last undamaged for so long and are easy to repair if needed.
    I'm very happy of how it turned, it asked a lot of time to complete this way but worthed it.

    This dog is an American Staffordshire Terrier, a sister breed of the American Pitbull Terrier that is more muscular, especially in the front part of the body but still very well proportionate. Skull is shorter but wider.

    Again, very nice Jean Christophe! It's definitely worth all the work you put in it, really a good piece!

    Fantastic work JC! I love the pose, and it's really neat that you chose to articulate it like the old specimens in the MNHN :) Hope you have the room to display it properly!
     
  4. Excellent action pose!
    Were the clavicles lost, or just not attached?
     
  5. Thank you ! Great that you like it ! :D

    I may keep using this way to articulate specimens big enough, really interesting to do this.
    I will show you where it sits on my shelf ;)

    From what I know, canids don't have clavicles, never saw them on any dog skeleton nor radiography... But otherwise it's quite complete, just haven't attached the tiny sesamoids between distal and medial phalanx because I'm not sure of how exactly to place them. And there was a bone from the throat but not from the hyoid.
     
  6. Canids DO have clavicles. These bones are too small to be detected by X-ray, and always lost by preparators who've been misled by wrong data.
    I became quite well trained in finding them, it requires thorough palpation of brachiocephalic muscle in shoulder joint area. Clavicles are usually embedded in ligament.
    Found them in domestic dogs and wild canids, such as dhole.

    Here are the clavicles of Russian Black terrier, male (top) and female (bottom). Yes, they're asymmetric.

  7. Ok, thanks, I've search again and found articles that study dog clavicles.
    http://www.ncbi.nlm.nih.gov/pubmed/3400932
    I have to say that when I prepared this dog I postulated that they were not present and haven't' particularly pay attention to this.
    Really strange that I can't see those on any of the load of x-ray pictures I have... I can see almost all bones but not clavicles on dogs but have several pictures that show them on cats. I even found them in the last polecat I dissected.
    Weird looking clavicles !

    Hope to get other dogs to see those by myself :)
     
  8. The probable reasons of clavicles' absence on x-rays are low density (not much higher than cartilage) and small size combined with thinness.
    Just remember, once you found the clavicle, grasp it with one hand, don't let it go and cut away the whole chunk of soft tissues around it ;) Or the nasty bone would slide several centimeters away and get lost again.

    I'll try to find clavicles in newborn puppies soon.

    It's amazing. Do you have a guide or a book to learn how to do it?

    The thread is a good 5 years old and the posters in that have been absent for a couple of years now. You did make your own thread on needing manuals and I answered that.

    But do look at Jean Christophe's pictures and go further to look at his website. His skills are amazing beyond par and you can learn a lot from just inspecting his work.
