Gastornis Diagrams by Bill Bankwitz The Gastornis skeleton is based on Kawahata's Kawahata's Brachiosaurus Skeleton and the Skeleton of the Tyrannosaurus Rex. in fact only a few of the pieces are used from both those models. Unfortunately to get the diagrams for the Brachiosaurus you need to buy the book Origami Dinosaurs 2and the . SKELETON SKELETON OF TYRANNOSAURU TYRANNOSAURUS S REX book. If you already already have them, have fun folding this this Bird Skeleton! Skeleton! If you don't have, please don't ask me for the diagrams because I'm not allowed to give you.

Construction
I always use florist wire and glue. And I always use a wood base and wooden dowels to support the models. The crackle finish that I apply will also give the model stability. See the finished model picture for assembly details. One point I will make is on that the back bone is instead into the tail cleft so the bones stick up and the ribs are ordered as follows 11/2 inch piece, 3 inch piece, all 4 inch pieces, finally the last 3 inch piece then the neck. The winds attach to the first or second ribs toward the top and a bird wing would be found. Finally the breast plate is attached under the ribs using the two flaps that were folded into the model to anchor it. You will have to shape the bottom of the ribs to get a good fit. This model is wet folded so the more shaping you do the better the model looks. You can get the bird skeleton sketch that I used on the inter net it is apart of the walking with dinosaurs pages, just do a search.
