RE: Shameless paper request, and a naive question

I would suggest a couple pubs.  

1) Carr, T.D. 1999. "Craniofacial Ontogeny in Tyrannosauridae
(Dinosauria, Coelurosauria)" Journal of Vertebrate Paleontology 19(3);
2) Carr, T.D., Williamson, T.E. 2004 "Diversity of Late Maastrichtian
Tyrannosauridae (Dinosauria: Theropoda) from Western North America"
Zoological Jouornal of the Linnean Society 142: 479-523

Subject: Shameless paper request, and a naive question

Shameless Paper Request:

Can anyone supply me with
Bakker, Williams, and Currie (1988). "Nanotyrannus, a new genus of pygmy
tyrannosaur, from the latest Cretaceous of Montana." Hunteria,
1: 1-30
I'd very much appreciate it. That's not fluff, I mean it.

Naive Question:

In the paper I am requesting, isn't it determined that _Nanotyrannus_ is
an adult, due to full ossification of the cranial elements? If this is
the case, how can _Nanotyrannus_ be a juvenile at all, let alone a
juvenile _Tyrannosaurus rex_? Is there some kind of awesome paper I'm
missing? And if there is, does said paper CONVINCINGLY refute Bakker,
Williams, and Currie's claim the cranial elements are fully ossified?
See, I told you it was a naive question.
