Better to ask those aging admirers of ‘Land of the Lost’!!!
The series ran 43 episodes from 1974 through 1976 began as an earthquake plunged rafters “a thousand feet below” to a mysterious world of stop-motion dinosaurs, furry Pakuni people, and bipedal reptilian cave dwellers called Sleestaks.

Perhaps still for some Freepers today! LOL
