Unknown (may not be real)
Dark green w/brown underbelly
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 Doc's nest only to have their teeth knocked out by him. They are presumably tyrannosaurids; possibly stylistic depictions of Daspletosaurus.
- Throughout their entire short appearance, they have the incorrect tripodal theropod posture.
- What species the sharpteeth are supposed to represent is unclear; some believe that they are tyrannosaurs such as Daspletosaurus or Albertosaurus, while others have proposed that they are Yangchuanosaurus.
