Carnivorous dinosaurs other than the famous t-rex and spinosaurus..

[DinoFan83]

I'd like to address some of Scott Hartman's statements in regards to Tyrannosaurus and Giganotosaurus size.

On his website (link), when comparing the sizes of Tyrannosaurus and Giganotosaurus, Scott Hartman states "As near as I can tell, despite Tyrannosaurus and Giganotosaurus appearing similar in size in side view, there is little question that T. rex is actually the larger theropod based on known specimens."
Many read this and believe Tyrannosaurus to undoubtedly be the larger, but this isn't necessarily true, for several reasons.
Here is why:

-As I have gone over above, there are several factors that end up underscoring the mass of Hartman's Giganotosaurus by a good bit compared to what the real animal probably weighed (such as too little soft tissue and a significantly too shallow torso); using the GDI of GetAwayTrike's likely better skeletal, we have a mass range of ~7.53-9.49 tonnes for the 2 Giganotosaurus specimens, compared to the ~6.8-8.2 tonnes of Hartman's skeletal as-is.
The upper end of this (~9.49 tonnes) outmasses the estimated ~8.4 tonnes for Sue, thus when comparing Sue and MUCPv-95 as Hartman did, but using GetAwayTrike's skeletal, Giganotosaurus would be the larger theropod based on known specimens, by well over a ton.

-Scott Hartman is using Sue as the representative of the entire species; not the best idea as it is a very large and old specimen in a sample size of over 30, and many adults such as Bucky and B-rex are significantly smaller than it. Moreover, when looking at our entire sample size of Tyrannosaurus adults, the average is about 6 tonnes as I have went over in the Tyrannosaurus thread, which both Giganotosaurus specimens and the average mass of them are larger than, by 2.51 tonnes.

-Even if Sue was larger than MUCPv-95, that wouldn't necessarily mean Tyrannosaurus was the larger animal as a species - we would, as previously stated, need to look at the mean mass of both species based on all specimens of both species to determine which was larger as it is a far better sample than merely maximum vs maximum.
As previously stated in this thread, there are many adult Tyrannosaurus specimens that both specimens of Giganotosaurus match or outsize (such as UCMP 118742, BHI 3033, MOR 980, LACM 23844, MOR 008, MOR 555, CM 1400, AMNH 5027, RTMP 81.6.1, RTMP 81.12.1, BHI 4182, MOR 1128, CM 9380, MOR 1125, and USNM 6183).
