Re: Non-theropod dinosaurs and feathery/fluffy integument

These are all larger genera. We're discussing smaller dinosaurs. Have any "slab fossils" similar to the Chinese theropod ones been found containing non-theropod dinosaurs?

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".
