I want to be the Bob DeNiro of the Jurassic.

I also got a chance to go to the American Museum in New York, which helped my interest.

Since then I have held many jobs at museums in Colorado and Wyoming. I have also taught summer courses at the University of Colorado.

Birds evolved from a small raptor like theropod.

Stegosaurus was common only on well drained, dry soil.

Feathers predate birds.

I also discovered the only complete Brontosaurus skull.
