Prehistoric Perils is a 1952 Mighty Mouse cartoon.
Oil Can Harry is holding Pearl Pureheart prisoner at his skyscraper lab. In the meantime, Mighty Mouse is also trapped under a magnifying glass in the desert...but not for long. He escapes and flies to Oil Can Harry's lab, where he clobbers the villain. In the midst of their battle, Mighty inadvertently ties Pearl to Oil Can Harry, and the three fall into Harry's time machine. Quick as a wink, the trio find themselves in prehistoric times (1 million years B.C.). Harry and a dinosaur chase Pearl. Mighty recovers, subdues the dinosaur (swinging brontosaurus around by their tails in the process), and traps Oil Can Harry inside the monster's false sharp teeth.
