The Last Dinosaur (極底探検船: ポーラーボーラ,   Kyokutei Tanken-sen: Pōrā-Bōra?, lit. Expedition Under the Pole: Polar-Borer) is a 1977 tokusatsu kaiju film co-produced by Rankin/Bass Productions and Tsuburaya Productions and distributed by Toho Company Ltd.


Wealthy big-game hunter Masten Thrust, using his company's advanced drilling vehicle, the Polar-Borer, leads an expedition to a mysterious underground pocket beneath the North Pole which is inhabited by several dinosaurs and other prehistoric creatures, including a tribe of primitive humans. The expedition takes a dangerous turn when a Tyrannosaurus rex destroys the Polar-Borer, leaving the crew stranded in a mysterious primitive world, where they are stalked by the T-Rex and various other dangerous creatures.
