The Last Dinosaur

Wealthy big-game hunter Maston Thrust Jr., played by Richard Boone, leads a group on an expedition to study a Tyrannosaurus rex in a prehistoric valley, where they are trapped and stalked by the ferocious dinosaur after their laser drill, the Polar Borer, surfaces into a volcano-killed zone. Alongside geologist Chuck Wade, Maasai tracker Bunta, photographer Frankie Banks, and Dr. Kawamoto, Maston's team tries to survive against the deadly creature in various ways, including using catapults and handmade crossbows, before ultimately deciding his own fate among the dinosaur's bones.
