Finally a realistic looking Spinosaurus!
But I prefer more feathers...
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.
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.
