Gamera vs. Monster X plus Monster from a prehistoric planet

"Relive the Golden Age of Japanese monster films with this pair of titanic adventures! First, Daiei's fire-breathing, flying turtle Gamera returns to battle a horned beast, Monster X, released from a stone statue moved from Wester Island. Facing off in Osaka, they create a demolition derby of destruction you won't soon forget! Then Nikkatsu Studios takes its turn in the monster sweepstakes with Monster from a Prehistoric Planet, made as Dai Kyoju Gappa and also shown as Gappa: The Triphibian Monster. In this loose, unofficial remake of Gorgo, a baby reptile-bird monster is captured and taken to Tokyo where its agitated mother and father come looking to reclaim their offspring!"@en
