Suborder: Theropoda
Family: Tyrannosauridae
Length: ~11.28 (Scott Hartman) to 12.3 meters (Scott Hartman)
Body mass: 5 to ~8 tonnes. Known from many more specimens than most other theropod dinosaurs.
Average weight 6 to 7 tonnes.
Age and Location: Late to end Cretaceous, Canada and United States
Diet: Large herbivorous dinosaurs
Weapons: Crushing jaw structure (Cost et al., 2019), pedal claws (Rothschild, 2013), manual claws (Rothschild, 2013)

Utahraptor ostrommaysi (pack of 12)

Suborder: Theropoda
Family: Dromaeosauridae
Length: 6-7 meters
Mass: 600-700 kg
Age and Location: 125 million years ago, Utah, United States
Diet: Other dinosaurs
Killing Apparatus: Raptorial jaws, manual and pedal claws
The largest known dromaeosaurid dinosaur. Thought to have hunted in packs.

Size comparison from earlier (just imagine 2 extra Utahraptors)

The utahraptors can win in a fight to death. Usually, a pack of utahraptors will be displaced by the t rex. Losing pack members will make one pack vulnerable to another.

[dinosauria101]

Yes, I agree with that.
The pack of Utahraptors is winning for sure in a fight to the death due to jaws, claws, numbers, and agility, but with some losses. And assuming they coexisted, those losses would be exactly what keeps T rex safe.

Funny though, across the internet I've seen people back T rex in this match. It's most certainly not a mismatch but I have yet to hear a good argument for T rex

That T. rex does not look right at all. Assuming each square in that size comparison represents 1 meter, then it's only ~2.5 meters tall at the hips and ~8 meters long.

Because it isn't. Anyway, i made a more appropriate one:

Utahraptor is 5 m long (based on 60 cm femur)
T-rex is just Sue
Both are from Hartman of course

[dinosauria101]

Well, looking a little closer the Utahraptors and the T rex are proportionately correctly scaled to match the dimensions of the other, so their sizes are correct. I think the scalebar's just a bit off.

I can't see whatever it was that Verdugo posted, so good only the scalebar squares are faulty

[Infinity Blade]

The Tyrannosaurus is markedly bigger in comparison in Verdugo's image.

[dinosauria101]

Maybe that's because of the Utahraptors. In the OP chart, they're Prehistoric Wildlife Utahraptors, which are 7 meters. But Verdugo's is 5 meters.

The T rex in the first comparison also looks to be SUe as it's 12.3 meters. I think this has to do with Utahraptor variability.
