John "Jack" R. Horner is an American paleontologist who worked on the production staff for the Jurassic Park Series as a paleontology consultant.
Horner is widely known for his discovery of Maiasaura, a dinosaur that backed up the idea that dinosaurs were parents.
He is also known for his belief that Tyrannosaurus rex was a strict scavenger, rather a predator. Horner backs this up by saying T. rex's sense of smell could be of great help finding carcasses, bone-crushing jaws were better for scavengers, and if T. rex ran at full speed and fell, it could die. However, this is not universally accepted with most paleontologist's accepting that Tyrannosaurus was an opportunist.

Jack Horner was the inspiration source for the character of Alan Grant (see Beyond Jurassic Park interview). Horner worked on the production staff for all Jurassic Park movies as a paleontology consultant.
Grants appearance is described as a "bearded man of forty" and black haired. This correlates with Horner's appearance.
Jack Horner was a paleontology consultant for all three films.
