How large is MOR 008?

UPDATE(7/4/2016): Even this may be a bit too large. MOR 008's maxilla and dentary measurements from the Theropod Database suggests that, based on AMNH 5027, MOR 008 was around ~11.97-12.22 meters long and ~6.26-6.66 tonnes in mass (taking a mass figure of ~6 tonnes for AMNH 5027). Not only it is now even further from the mass of FMNH PR2081 than I thought before, it's turns out that it doesn't even grab a length advantage.

Not as large as many Tyrannosaurus fans think it is.

The ~1.5-meter reconstructed skull seems to be exaggerated, reconstructing it like a normal Tyrannosaurus skull actually gets it down to ~1.34 meters from snout to the quadratojugal.



It appears that agrees with this: comments.deviantart.com/1/1241…

So how large is this specimen? Well, it is pretty similar to AMNH 5027(they were both assigned to "Tyrannosaurus X"), so it seems to be a good base to use.

And here's the result:



It's still one of the largest known Tyrannosaurus specimens, but due to it's more gracile build, still smaller than FMNH PR2081.
