Let us keep in mind that what the data shows is that big sections of the
majority of dinosaur skin was scaly. But that they also show that when you
have relatively complete coverage of the individual (Psittacosaurus,
Juravenator, more to come soon) you get bodies which are mostly scaly but
with isolated patches/lines of filamentous integument.
