Do we really know enough about Tyrannosaurus' nesting behavior and the
juveniles to speculate?  It seems the arms were utilized at some point in
time.  Whether to climb trees, break out of an egg or to build nests.
 Considering the precariousness of their balance, the added frontal weight of
the arms must have served some purpose other than a vestigal remnant.
 Perhaps while still young (and moderately sized) the arms assisted in
grabbbing onto prey, becoming less functional as their size and jaws grew.
