Paleontologist Jack Horner discovered the first dinosaur eggs in the Western Hemisphere, the first evidence of dinosaur colonial nesting, the first evidence of parental care among dinosaurs, and the first dinosaur embryos.

Horner's research covers a wide range of topics about dinosaurs, including their behavior, physiology, ecology and evolution. Due to struggles with the learning disability, dyslexia, Horner does not hold a formal college degree but was awarded an Honorary Doctorate of Science from the University of Montana in 1986. Also in 1986 he was awarded a MacArthur Fellowship.

He's the Curator of Paleontology at the Museum of the Rockies in Bozeman, Montana, and is widely acknowledged to be the inspiration for the main character in the book and film Jurassic Park.
