In Dino Veritas

S2 E7: The slide brings the Sliders to a primeval forest and dumps them into a giant egg-filled nest, irritating the mother allosaurus nearby. As they flee from the rampaging dinosaur to a cave, one of them gets hurt and drops the timer. Quinn (Jerry O'Connell) leaves the safety of the cave and faces the man-eating allosaurus in an attempt to retrieve the timer. With John Rhys-Davies, Sabrina Lloyd and Cleavant Derricks.
