Aha! My suspicion, then, without getting the X-rays and such, is that the
original is simply lacking the distal portion, and was restored with the
expansion after Allosaurus (then the only adequate model for T. rex). The
Carnegie specimen is (in)famous for some restorations that, in hind sight,
are rather unfortunate.

That is most excellent to hear!! That skull, and those feet, need fixin'...
