On what basis is the lack of tyrannosaur tooth finds evidence of this? Is it
a given that a tyrannosaur not only would lose teeth but also that those
teeth _must_ be preserved as fossils? I would think that, aside from
speculation, the evidence is inconclusive at best; especially if the
evidence cited is an apparent absence of something.
