Re: Hyoid bones



Marco,
I also study the hyal apparatus, primarily of mammalian carnivores.
You will note that few reconstructions of fossil animals include the hyal bones.
To adequately answer your question, dissection of living analogs would be 
valuable.
If your funds permit it, you should also look into using an X-ray videograph on 
extant
analogs.

The problem, as you have found, is that the numerous ligaments and cartilages 
stretch and contract during various normal movements of the jaw, tongue and 
pharynx.

Dear DMLers,

I need an info about the couple of hyoid bones. I dont know if, with 
the movement of the tongue, the hyoids follow partially the direction 
of the tongue, and then if is it possible that in a lateral skull 
recostruction the hyoids are visible laterally, or they remain ever 
under the limit of the mandibles?

Thanks in advance
Marco
