Feathered Dinosaurs and the Origins of Flight
Kids meet Deinonychus
Therizinosaur: The Ultimate Big Bird
Feathered Dinosaurs and the Origin of Flight,
an exhibition at the Arizona Museum of Natural History from March 1 through
September 28, presents exciting evidence from remarkable fossils discovered
in China that are bringing new answers to the on-going debate about the
relationship between dinosaurs and birds, as well as how they evolved the
ability to fly.
The exhibit is a rare opportunity to see firsthand a collection of 35
fossils that are national treasures on loan from the Peopleâ€™s Republic of
China. These fossils reveal a new understanding of how birds are related to
dinosaurs. Also on display are many life-size recreations that demonstrate
startling changes in how dinosaurs have been portrayed over the years.

1. The fossil of Caudipteryx preserved not only the bones, but
also impressions of feathers from the wings and tail. Caudipteryx was
originally thought of as a small feathered dinosaur, but it was actually a
very primitive bird which had lost the ability to fly, much like the Ostrich
of today. The Dinosaur Museum Â© 2004.

Caudipteryx fluoresce in ultra-violet light and appear a bright golden
color. The Dinosaur Museum Â© 2004.
3. Caudipteryx sculpture. The life restoration of Caudipteryx
based on information from the fossil revealed that it had a very bird-like
appearance. Caudipteryx was not capable of flying. Sculpture by
