Negative allometry in tyrannosaurids?

["Jordan Mallon" <j_mallon@hotmail.com>]

I don't know what shape the juvenile specimens that we know of are in, but 
does anyone know if the tyrannosaurids exhibit negative allometry with 
respect to their forearms?  And if they do, what would this suggest?  That 
the arms were useful at a young age and became progressively less so as the 
animal grew older?
With the presence of long arms in _Eotyrannus_, I would expect the answer to 
be "yes" if we consider the idea that "ontogeny recapitulates phylogeny."
Just wonderin'.  Thanks.
