Lots of interesting prehistoric news these days. Like Spinosaurus, this one will not be settled any time soon.

So... Basal tyrannosaurids have this dentary groove. Albertosaurines have it. Juvenile tyrannosaurines have it. Adult tyrannosaurines lack it. But this makes Nano valid AND an slbertosaurine...?

Sorry to be harsh but what is it with nano supporters and the inability to even attempt good science? The fact that this is simply a basal trait retained in juveniles is obvious just from the abstract. Total failure of peer review.

I guess some folks just love the idea of a little tyrannosaur running around.

I have not yet seen amazing proof for either side of the debate to warrant an answer either way.

Another thing I don't get. There were lots of little tyrannosaurs running around. Whether they were their own species or juveniles of something else doesn't really change anything about them or their ecosystem. It's an argument over a name.

So Nanotyrannus is now an Albertosaurine?

Indeed. Frankly, I have trouble envisioning how Nanotyrannus would have been able to eke out a living with so much competition from growing T. rexes.

No, this paper is garbage.

I agree.  Seems odd.  But then again, Leopards and Lions co-exist in the wild.  And if this case is similar, I think poor Nano would have been lower on the food chain.   Perhaps they would be the scavengers that T-Rex has been envisioned as for many years.
