Unknown (probably imaginary)
Dark green w/brown underbelly
The Lone Dinosaur's nest
One day when he was roaming alone out in the west, a vicious pack of sharpteeth came and gobbled up his nest
These Sharpteeth appear in The Land Before Time VI: The Secret of Saurus Rock, during The Legend of the Lone Dinosaur song number, where they destroy the Lone Dinosaur's nest only to have their teeth knocked out by him.
- Throughout their entire short appearance, they have the incorrect tripodal theropod posture.
- What species the sharpteeth are supposed to represent is unclear, if they are a species at all; some believe that they are tyrannosaurs such as Daspletosaurus or Albertosaurus, while others have proposed that they are Yangchuanosaurus.
