Hi
variation in the number of vertebrae, most commonly lower thoracic or
lumbar occurs in all mammals. There is evidence of a genetic
predilection which may translate to breeds (i.e. Arab horses are generally
considered to have one less vert - but I haven't seen the evidence for
this).

Hello
Zooarchers,
Could you help me out? I have three questions regarding
sheep:
- Is there a reference for reconstructing size of sheep from other
bones
than metacapals/matatarsals? I have a series of sub-complete
skeletons for
which only the head and lower limbs are missing (cut off
under the
carpals/tarsals)...
- Does any one know how long have polled
breeds (both male and female)
existed?
- Apparently, sheep can have
either 6 or 7 lumbar vertebrae. Is that
breed-related? Does any one have
any information on the chronologic
evolution of this
caracteristic?
Thanks in advance for your help!
All the
best,
Annelise
