The Land Unknown

A small crew led by Commander Harold Roberts (Jock Mahoney) and reporter Maggie Hathaway (Shirley Patterson) are on an expedition into Antarctica. During a helicopter flight they fly into the storm, where they almost collide in mid-air with a man-sized pterosaur, they crash-land well below sea-level in a warm volcanic crater. Inside, they discover a steamy tropical jungle populated by living dinosaurs, giant flesh-eating plants, and fresh human footprints. The crew encounters many dangers and perils in the jungle in a fight for survival. The film is notable for its low-budget special effects, which include men in dinosaur suits, puppets and monitor lizards standing in for dinosaurs. The animals featured in this film include a Tyrannosaurus, Elasmosaurus, Stegosaurus live acted by monitor lizards (which would technically make them Megalania), a pair of Pterosaurs and a giant flesh-consuming plant.
