Re: Non-theropod dinosaurs and feathery/fluffy integument

This means that all dinosaurs outside this clade
(which are, in fact, most dinosaurs) would still be
scaly. This has been supported by the numerous skin
impressions from Carnotaurines, Sauropods, Ceratopians
and Hadrosaurs; all of which show scales.

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?

All dinosaurs had integumentary covering. Scales ARE a
type of integument. As for filamentous integument,
that is probably restricted to coelurosaurs only
(probably closer to Maniraptora too).

Is there another, less cumbersome word for that sort of integument? I thought I saw a word ("pellage" or something) used to denote feather/fur-type integument on this mailing list, but it may be my memory tricking me again.

I don't see why not. I'd have to wonder what
environmental forces were pushing for nappy hair
though.

Maybe nappy integument was considered attractive among certain species? It could have been sexual, as opposed to natural, selection at work.
