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.
i like it
Finally a realistic looking Spinosaurus!
But I prefer more feathers...
It is actually about 30% heavier than I usually though, and a lot more similar to my first guess.
What images did you use for it?
Also, my estimate for MUCPv-CH1 varied from 6,590 to 6,813 kg, the first one was incredibly similar to the figure Seebacher gave (6,594 kg) and the second one was surprisingly similar to the figure Hartman gave (6800 kg).
I just did three drawings from different views, I just did the drawings section by section and estimated the weight of each section, I had to separate the spines from the torso to give a good estimate, I precisely used the same dorsal views as in the Article: A Computational Analysis of limb and body dimensions with implications for locomotion.
But instead of using 3D models based on mounted skeletons I used 2D models based on the Hartmans skeletals.
And they were surprisingly accurate, I gave 3900 kg for the holotype of Suchomimus tenerensis, Which matches almost perfectly with the estimation Seebacher gave in 2001 of 3816 kg.
What I meant was: Where did you take the data you needed to make a dorsal or anterior view from? I don't recall any rigorous spinosaur-dorsal-view skeletal existing.
I mean, I just imagined how would spinosaurus look dorsaly based on Acrcoanthosaurus spines, but I had to reduce the ribcage.
I used the 3D Acrocanthosaurus as a basis of how much flesh could have been attached to the spines, then scaled to Spinosaurus.
That Acrocanthosaurus is probably a good base for the dorsal view.
Have I ever suggested you to join at World Of Animals (theworldofanimals.proboards.co...? You should really share your results on that forum, the community there would be very interested!
You may be right. 12t is just my lower bound to its weight, that's why I wrote "12t+"
I fear if I wrote 14t, I would soon get tons of comments saying how ridiculously high my figure was. Anyway, 14t is reasonable.
"it had a sail!"
"there´s no reason to suspect this, the spines are more similar to non-sailbacked animals"
"it had a sai, end of debate"
What does this guy think is the natural purpose of the spinosus process? Certainly not spanning skin.
