Large Flat Bone--Rib?

[Brandy Cole]

I found this large, flat bone fragment in a southeast Texas gravel bar.  

Not sure if there's enough detail here to make a solid ID, especially on the articular process.  I tried comparing it to other large mammal flat bones like ribs and scapulas, but couldn't figure it out.

Hoping someone with more experience can help ID it. 

Thanks for any help!

Scapula fragment - large sized animal

Agree, looks like a scapula to me. Not sure which large mammal.
