vertebral air sac

[poponpo]

The other day, I was indebted to you for the spinosaurus vertebral fossil.

I have a question.

Does the dinosaur's air sac match the marked part in the picture?

The fossil in the photo is the sacrum of spinosauridae.

Thank you .       (⌒‐⌒)

I compared the depressions in your specimen to similar ones in a Spinosaurid sacrum found in the UK.  The publication makes the following remarks about those depressions:

"These depressions do not house pneumatic foramina, and their poor development indicates these are unlikely to pertain to a pneumatic system."

 

So based on those comments it does not appear to be what you call " part of the air sac"

From Google Translate:

 

Thanks guys. The characteristics also vary depending on the type and position of the bone. I learned.
