Robert Bakker
Bakker has been a major proponent of the theory that dinosaurs were warm-blooded, smart, fast, and adaptable. His main work, The Dinosaur Heresies, was published in 1986. He revealed the first evidence of parental care at nesting sites for Allosaurus. Bakker was among the advisors for the film Jurassic Park and for the 1992 PBS series, The Dinosaurs.
