Interesting. L'd never heard of 4 wing dinosaurs.
I've seen some huge dragonflies that always remind me of some prehistoric (or alien!) movie or something.
Four winged dinosaur?
Strange, isn't it?
"This is the living creature that I saw under the God of Israel by the river of Chebar; and I knew that they were the cherubims.
Every one had four faces apiece, and every one four wings; and the likeness of the hands of a man was under their wings."
