Re: Psittacosaurid hair!

Well folks, ornithischian "hair" seems to be a
reality. HP Michael Schmidt was kind enough to send me
several nice photos of the integuments on a
Psittacosaurus (?sp). The first word that came to mind
was "porcupine." Whether or not the structures
actually represent quill-like objects, they do seem to
be thicker than I would imagine.

I recall that integument/epidermally derived spikes were recorded for a sauropod (?Diplodocid?) specimen from N. America. Can anyone confirm?
