Need help identifying scapulae

[frearky]

Hey there,

 

I need some help identifying 2 scapulae. All we have been told is that they are in some way related (although this relation could be as simple as both bones being scapulas).

 

The first one looks a lot like a humans scapula, so we're suspecting it is a biped, more than likely a primate.

 

The second one is a lot narrower, has a very large spine, barely any coracoid process and seems to have a deep glenoid cavity.

 

Any help would be greatly appreciated. I'll upload pictures of them, if the image labels don't get displayed, the more pale bone is the one I am referring to as bone 1.

 

Thanks

Do you have a plain lateral view?

 

The glenohumeral looks chunky enough to be load bearing.

 

Only mammals and marsupials have corocoid processes - I think the others have a separate corocoid bone

 

bear have a second ridge in the infraspinous fossa,

cats are more gracile and different proportions,

dogs have no clavicle and thus no acromoclavicular surface

horses are just bigger and different shape

not gorilla as that seems very similar to ours

 

still no ideas

dog looks best

although what about Baboon - or other larger animals that straddle gap between bipedal and quadrapedal

final guess - is it an early hominid? Although I think it v unlikely you would be given one of those to play with

I know nothing about bones, But when looking at them I thought of chicken, Which I know they are not, But they look light with what seems to be a large amount of air cavities, So could they be something like an Ostrich/emu?
