Revised Spinosaurus skeletal
Here it is. I'm sure people will have opinions on it. I'm happy to answer questions, but if you want more detailed information I wrote extensively about my choices and assumptions on my website:
And the article on sail shape I posted in the last journal:
Spinosaurus sail shape
I see what you did there. I do think the neural spines would sustain damage from moving beyond the normal range of the tail. But since they are almost certainly being held in by skin and connective tissue they would probably heal to some degree most of the time. This was exactly why I didn't straighten out every neural spine perfectly from the fossil condition.
Thanks. To be clear, the fossils don't clearly favor one hypothesis over another. On my website I actually show off a couple of other hypothetical sail shapes that would also work as far as what we know right now.
That's ok! Of course there are other possibilities too (like they are both reliable...or that neither is). All we need is another dorsal from the FSAC quarry to know about that one at least.
