Sliders (1995)

S2E7 In Dino Veritas

The Sliders arrive in a dimension where San Francisco has transformed into a national park focused on dinosaur conservation, inhabited by a fearsome Allosaurus. After a misstep, Arturo sustains an injury and misplaces the timer. While the rest of the group seeks refuge in a cave from the lurking dinosaur, Quinn ventures out solo to locate the lost timer.
