It's interesting..I do wonder how long it will be before someone says it's just a juvenile though..

I was thinking the same thing, but I believe they mentioned something about the teeth being to small to be a T-Rex for what that's worth.

No, its not a juvenile of anything. This is actually a fully-grown tyrannosaurus, since like torosaurus, they shrink as they grow.   
I really need to keep up with these new finds, I haven't been keeping track for a while.

In more comprehensive articles the authors of the paper actually mention that--more material is needed to verify that this isn't a juvenile. There's features that indicated, to them, that they were dealing with an adult though.

Of course, it could be a juvenile of a non-Tyrannosaurus rex too. Time to start searching the arctic for more fossils.

Ah.  I will leave that to warmer-blooded folks than I  .

There's no way it's a juvenile T. rex, since it lived about 4 million years prior to T. rex (this is the species the "Gorgosaurus" in WWD movie was based on. These fossils were previously considered to be Gorgosaurus or Albertosaurus).

If it's a juvenile, it's a juvenile of either a new species or of Tarbosaurus bataar which lived about the same time across the land bridge in Asia. But we have juvenile T. bataar to compare with so that seems pretty unlikely.

"This is actually a fully-grown tyrannosaurus, since like torosaurus, they shrink as they grow."
(I'm taller than my dad, so I guess humans shrink as they grow too!  )

Okay, Carr, what's the difference between Jane and this guy? I suspect the difference is "I didn't discover Nanotyrannus"
