The Carnosaur film series consists of B-movies produced by Roger Corman that feature genetically engineered dinosaurs running amok in various scenarios. The series started with the first Carnosaur film, released in 1993, that was loosely based on the 1984 novel Carnosaur by John Brosnan. Two sequels were released direct-to-video: Carnosaur 2 in 1995, and Carnosaur 3: Primal Species in 1996. Two subsequent films use footage from the Carnosaur films: Raptor (2001) and The Eden Formula (2006).
