Bertram is one of the protagonists of the first Dinoverse Books “I Was a Teenage T. Rex” and “The Teens Time Forgot”, (later re-released as a single volume).

He created the MIND Machine: a memory interpreter and visualizer that somehow zaps him and several others and bodyswaps them with prehistoric creatures.

Due to the MIND Machine, Bertram bodyswaps with an Ankylosaurus who serves as his host for his prehistoric adventure.
