My reconstruction of S. aegyptiacus.
Some told me it looked "whale-like", others found it too bulky. So what?
There's a base for that, and that's the fact Spinosaurus had damn vertebrae, indicating a very long and deep body.
I used my skull reconstruction to fit IPHG 1912 VIII 19's postcrania and dentary together with MSNM V4047's rostrum and filled in what was left with the proportions of Cristatusaurus/Suchomimus and Baryonyx. Due to the much longer vertebrae seen in the holotype, I increased the torso's lenght a bit. I could have done the same with the tail, but I left it like it was.
In the end, the whole thing ended up at ~15m in tip-to-tip lenght, which means in axial lenght as usually given it would be ~16m or more (for comparison, sue the T. rex gets about 70cm shorter than fully stretched if it is in a normal pose).
For mass, my guess would be 12t+
This is not overly liberal but it is a different approach to the far too common reconstruction of an elongate, long-necked animal, contrary to what the remains indicate.
