Which company created the CGI dinosaurs for the 1993 Jurassic Park film?

Industrial Light & Magic created the CGI dinosaurs for the 1993 film Jurassic Park.

ILM, the visual-effects company founded by George Lucas, handled the groundbreaking computer-generated work. Its artists built digital models and animation for creatures including the Tyrannosaurus rex and the Gallimimus herd, helping make the animals appear integrated with live-action footage.

The film did not rely on computer graphics alone. Stan Winston’s team built large-scale animatronic dinosaurs for close-up and practical shots, while Phil Tippett developed stop-motion and go-motion concepts before ILM’s digital approach took over many shots. That division of labor is why answers such as Stan Winston or Phil Tippett can sound plausible, but ILM is the canonical answer for the CGI work.

Jurassic Park’s effects, supervised at ILM by Dennis Muren, helped establish computer-generated creatures as a major feature-film tool. The visual-effects team won the Academy Award for Best Visual Effects, and the film’s digital dinosaurs became a landmark in cinema history.
