Grays-raptor-flock/ Thanks for commenting. I nearly forget to answer these comments.
TheMorlock/ I found more.. And there was a words saying "a 30 square centimeter skin impression was found on juvenile allosaurus's left side."
As much as my liking for feathers, I think it is important to know and use most information of fossil evidence. It is not as simple as feathers good, scales bad..
However, I don't go aginst allosaurus with some feathers.
Just.. I think that drawing has too many of it.
