I don't know what this statement was in refernce to.

However, no: the largest T. rex teeth are absolutely larger than the largest
Daspletosaurus teeth.

Because carcharodontosaurids simply retained the ancestral condition rather
than evolving a new state. Different strokes (or bites) for different folks.

Most likely the latter, as argued in (among others) my chapter in the T. rex
symposium volume.
