A male Tyrannosaurus appears in The Land Before Time IV: Journey through the Mists during the opening narration. He is a Sharptooth, specifically a Bigbiter Sharptooth, a fan-derived term for tyrannosaurids in the franchise. He lives in the Mysterious Beyond, just like most other sharpteeth. He is presumably a male, judging by his dark coloring in a pre-art shift film.
In the opening narration of the film, he is shown chasing a flock of Dryosaurus. It is unknown if his hunt was successful or not.
- Some fans believe that this is actually Chomper's Father, due to the coloring of the two sharpteeth being very similar. However, the sharptooth in the beginning of this film's eye color is of a different shade, and is dark brown rather than dark green.
