Dinosaur Behavior

[CORTESM1919@aol.com]

The Jurassic Park Films (Part III to premiere soon) gained audience appeal to 
movie audiences everywhere.  The films suggested that dinosaur behavior was 
attributed to "bird like" characteristics. This was a new concept for me 
since I was first exposed  to the concept of behavioral similarities between 
dinosaurs and reptiles.  I would like to inquire on how did the bird behavior 
theory first came about and those supporting it. Is this theory accurate and 
if it is what evidence supports it?  Did dinosaur behavior determine 
intelligence, if so how?
I would appreciate if anyone could suggest references such as websites, 
books, academic journals to expand my understanding of dinosaurs.

Thank You.
