Psittacosaurus specimens from Liaoning are covered in scales except for the
apparent quills on the tail, which are quite different-looking from
feathers, even if they are homologous.
Juvenile Allosaurus have been found with scales, as has Juravenator and
Epidendrosaurus (on the tail in the latter two). Santanaraptor shows naked
skin, however. Of course these taxa could have had feathers on other parts
of their bodies (Epidendrosaurus may preserve feathers, but these may be
collagen instead). But that could be said for most skin impressions of
larger dinosaurs too (Carnotaurus, tyrannosaurids, sauropods, ceratopsids),
with the exception of Edmontosaurus and Brachylophosaurus.
And there's the often mentioned, seldom studied, Thescelosaurus skin which
was said to be unscaled and "punctured".
