The Valley of Gwangi (1969)

You’ve heard of Cowboys and Aliens… now get ready for cowboys battling dinosaurs! Centered on the mysterious Forbidden Valley where prehistoric creatures roam free, the ferocious allosaurus known as Gwangi is captured and displayed in a rodeo. Naturally, catastrophic mayhem ensues. Originally thought up by Willis O’Brien, Ray Harryhausen continued the project, creating its stop-motion effects.
