In places like the Dinosaur Park and Kaiparowits fms, plenty of ceratopsian postcrania has been collected (with and without skulls), and hadrosaur skin is still way more common. One thing I find very odd is that Davis doesn't bother to look at average sediment accumulation rates for formations that preserve these fossils. I'd think that the higher the average accumulation rate, the more likely you are to get more skin impressions.
