I love the idea of this, but the size of their chest cavity leaves me wondering if it's feasible.
Would there be heavy ligament anchor points on the bones? It seems like there would be evidence of a completely different muscle build, maybe simply by the size of the spine bones themselves. I'm no bonologist, though.
And yeah, that chest is gnarly (but I'm no chestologist).
