Oh, and did get a chance to check with the tyrannosaurid skin impressions at the RTMP. They do have mosaic scales, but these are smaller than those on typical hadrosaurid or ceratopsid skin (actually, the collections specimen is about as small-scaled as Gila monster scales).
What does this suggest about feathers and tyrannosaurid evolution?
