Hang on a minute, I was not the author of the above statement, it comes
from Dinogeorge's reply to my posting. Personally, I think you are
probably right, Longisquama had elongated scales (display structures?)
that happen to look vaguely lie feathers (emphasis on the word vaguely).
I also hope Dinogeorge wil discuss his reasons for including this
creature in Dinosauria. Does anyone have a reference for a good
description of this animal?
