An unfeathered bird, drawn loosely from Katrina van Grouw's wonderfully beautiful book The Unfeathered Bird
. If you have any interest in birds, dinosaurs or anatomy, you must have this book.
Birds look really weird without their feathers. Their dinosaur ancestry also becomes obvious, when their anatomy is actually visible. Just add a tail and some teeth, and you have a non-avian dino. And that's exactly what Jack Horner's Chickenosaurus
project is about. See here: [link]
