Tunnel Through Time

Tunnel Through Time is a 1966 science fiction novel written by Paul W. Fairman under American science fiction and fantasy author Lester del Rey's byline. It is a children's time travel adventure.

Plot summary
The novel tells the story of a teen named Bob Miller whose scientist father, Sam Miller, has invented a "time ring", a circular device that allows time travel. Bob and his friend Pete travel through time in search of Pete's father ("Doc Tom", a paleontologist) who has disappeared while traveling alone. Beginning in the Mesozoic Era, Tom's planned destination, the story depicts various adventures while the travelers jump from point to point in Earth's prehistory; although they are able to locate the missing Dr. Tom Miller almost immediately upon arriving in the Mesozoic era, the time machine is unexpectedly damaged when a dinosaur runs into it. As a result, the three are unable to immediately travel directly forward through time to their present, and instead are forced to "hop" through different eras of prehistory until they finally arrive home.
