For those of you that are wondering about 10-12 tonne Spinosaurus, we do indeed have a specimen that would be about that large: NMC 41852. 

It's a partial humerus that would have measured 75 cm when complete when compared to the humerus of Baryonyx, and when applied to Spinosaurus skeletals, it would be 16.76 to 17.12 meters in axial length (link).
Assuming a 15 meter long Spinosaurus is around 7.5-10 tonnes, this animal would scale to roughly 10.46 to 13.94 tonnes if it was 16.76 meters, and roughly 11.15 to 15.84 tonnes if it was 17.12 meters (I'd consider anything much above 13-14 tonnes.to be a tad too much BTW).
This would make Spinosaurus the largest theropod, outmassing the largest Tyrannosaurus specimens by at least 2 tonnes and the largest carcharodontosaurids by at least 1-2 tonnes. Reply
