The Neo-paleontologist Dan Folkes building up a Skeletal model of Scotty with a 3D model that estimates the body Mass of the specimen at 10624.895kg aka 10625 kgs or 10.6 tonnes, with also a very reliable study saying :

An Older and Exceptionally Large Adult Specimen of Tyrannosaurus rex
“Here we describe an extremely large and relatively complete (roughly 65%) skeleton of Tyrannosaurus rex (RSM P2523.8). Multiple measurements (including those of the skull, hip, and limbs) show that RSM P2523.8 was a robust individual with an estimated body mass exceeding all other known T. rex specimens and representatives of all other gigantic terrestrial theropods”
Scotty was a massive animal its femur measures around 133 cm in length with a circumference of 59 cm. Sue’s femur measures 132.1 cm in length and only has a circumference of 57.5 cm the femur is a very important weight bearing bone. While Scotty’s skull is mostly complete, the possible length estimate of 161 cm that’s 9 cm more than Sue’s estimated skull length. Based on the skull and femur size its likely Scotty measured between 12.67 and 13.08 meters and could have weighed anywhere from 8,870kg (9.7 tons) to possibly 10,490 kg (11.5 tons). This makes Scotty the new record holder for largest T. rex and the largest land predator just surpassing the previous record-holder that was originally Sue.

Scotty exceeds Sue in 84.6% of the published measurements. All of Scottys weight bearing elements are larger than Sues are.

The pubis has a direct coalition with the torso of an animal and is important when determining of torso depth. So it is highly likely that Scotty had a even deeper wider torso than the Sue specimen.
Scotty also has a larger ischium bone along with multiple caudal vertebrae that are thicker than Sues are. Scotty's whole hip girdle is more robust than Sues is and this is important because the hip girdle is the centre mass bearing structure for a theropod dinosaur. So its highly possible that Scotty carried around more weight than Sue did.
The rest of Scotty's body collectively implies a much brawnier body shape than other big Tyrannosaurus specimens and other big theropods. Plus a comparison of cubic femoral dimensions gives a much greater overall weight.
The latest study regarding Scotty describes its shoulder bones, hips and it's leg bones and they are all larger with Scotty than the corresponding bones in the Sue specimen. Scotty's bones were also examined and show higher levels of stress from carrying around more weight when compared to the bones of Sue.
Using the study by Snively et al 2018 we can compare the cross sectional of the sacral anterior vertebra. This is the method used to show the relationship between the animals body mass and the cross section area of the animals spine by showing the mass of an animal but also the stress of the upper body.
The results are once again higher for Scotty than they are for Sue. Scotty's cross sectional area was found to be 650 cm ^2. This means that Scotty was 4 percent larger when compared to Sue who's results were 625 cm^2.
Quote from W. Scott Pearsons

“It wasn’t until now we’ve been able to take a step back and look at the specimen as a whole, “And doing so there’s an oh gosh moment because the specimen really is enormous.”

“We looked at this from a number of different angles. Obviously the best way to do it is the direct one-to-one comparisons through the various skeletal elements,” Persons said. “When you look at everything from the shoulder to the hip to the leg to portions of even the toe bones, yes, Scotty the Tyrannosaurus rex comes out consistently just a smidgen-bit larger than Sue.”

‘I think there will always be bigger discoveries to be made, but as of right now, this particular Tyrannosaurus is the largest terrestrial predator known to science.’

While Persons is very happy about presenting Scotty to the world, he believes Scotty won’t be the largest for long.



Both Sue and Scotty had their weights estimated in the latest study both specimens were directly compared. The method used to calculate the mass in the latest study was the same for both of the specimens and the data shows that Scotty is more massive than Sue is.

is not scientifically enough for you? There's more than clear evidence of Science quoting the largest tyrannosaurus to be estimated at over 10 tons, not only if we consider this weird unverified SCIENTIFIC study claiming that tyrannosaurus could be 70% larger than we previously thought

While I don't buy this study at all, it's another clear indicator that the Tyrannosaurus specimen Scotty  is estimated to be over 10 tons unlike you tried to frame there with a very big claim that obviously was based on thin air.



Moreover, there's no OFFICIAL SCIENTIFIC PAPER with a GDI of Volumetric scan estimating Spinosaurus to be 10+ tons, and Nizar's Ibrahim was just a guess-estimate based on new densities that would have later been applied for theropod mass estimantions.

More over, when looking at the dorsal view made by the same dan folkes it's clearly visible how the largest reported Spinosaurus (not largest verified, because I remind that the largest verified Spinosaurus is the estimated 3.7 ton holotype, while studies list the largest specimen as even another species or just don't classify it as Spinosaurus Aegyptiacus) does not compare in any department to a 10+ ton tyrannosaurus rex or a 9+ ton Giganotosaurus Carolinii (and Dan allegedly GDIed the Spinosaurus at 7+ tons), as it's much more gracile and narrow in built, not only its ribcage is light years far from being as wide as the other two megatheropods, but even when comparing the vertebrae the difference couldn't be more clear:
