so i noticed that there is a debate about what is the max size for tyrannosaurus spinosaurus and giganotosaurus and i studied all of these animals and here are my conclusions
Tyrannosaurus X
max confirmed length: 12.57 m ( MOR 008 )
max confirmed weight: 7.4 tons ( MOR 008 )
max estimated length: 14.12 m ( MOR 1126 )
max estimated weight: 8.6-9.8 tons
Tyrannosaurus Rex
max confirmed length: 12.3 m ( FMNH PR2081)
max confirmed weight: 9.1 tons ( FMNH PR2081)
max estimated length: 13.57 m ( MOR 1152 )
max estimated weight: 9.8-11.3 tons ( MOR 1152 )
BTW i recently found out that c rex ( MOR 1126 ) proportions were 100% X while f rex ( MOR 1152 ) is closer to rex than x that is why i put it here;
Giganotosaurus Carolinii
max confirmed length: 12.2 m ( MUCPv-Ch1)
max confirmed weight: 6.8- 7.6 tons ( MUCPv-Ch1)
max estimated length: 13.35 m ( MUCPv-95 )
max estimated weight: 8.2-9.8tons ( MUCPv-95 )
Spinosaurus Aegypticus
max confirmed length: 14.3-16.5 m ( BSP 1912 VIII 19 )
max confirmed weight: 7-8.5 tons (BSP 1912 VIII 19 )
max estimated length: 17.8-18.2 m ( MSNM V4047 )
max estimated weight: 11.7-12.8 tons ( MSNM V4047 )
BTW the holotype speciemen ( BSP 1912 VIII 19 ) had an 85 cm long lower jaw maxilla while ( MSNM V4047 ) had a 92.3 cm long one

so that was it hope you liked it please leave your comments
well dinosteve at first i thought so too but based on the thickness of baryonyx's and suchomimus's legs it would be around 12.8 tons especially because it lived 55% of it's life underwater
I still believe Spino couldn't get more than 8-9 tons. The rest 45% of its life would be spent out of the water. Don't forget that spinosaurids were light-built, if you take or not their leg thickness.

yes dinosteve you are right they are very light built but not like deltadromeus or bahariasaurus for example, plus an 17 m long tyrannosaur or giganotosaur would 25 tons +!!!!! so 12 tons for spinosaurus is not that big of a stretch
Careful how you word things raptorexxx ;)
Decent estimates, although 25 tons is way too much for any bipedal animal.
Let's be a little careful with Tyrannosaurus X shall we. It's technically not a recognized species and I've never seen anything published about it. Just saying.
