in the children's book We're Back, a group of friendly and intelligent dinosaurs are transported to the present day, where they hope to entertain children at the natural history museum. instead, they are rejected by a suspicious populace who resent and fear the misunderstood creatures. the book ends with the dinosaurs cowering in the basement of the museum while the police relentlessly search for them, a modern-day gestapo rooting out hidden undesirables. it was later adapted into an animated film featuring the voices of John Goodman, Jay Leno, Walter Cronkite and Martin Short
