The spines on a buffalo are a lot thicker and shorter. Any muscle attached to the spines of a spinosaurus would snap them in half.
Also the buffalo's spine bones are elongated over it's shoulders, whereas the spinosaurus has elongated spine bones start after its shoulders.

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).
Interesting idea. Aren’t these huge neck muscles mainly for supporting their huge head while grazing?
