A pack of six Deinonychus - called Sharpteeth (or Fast Biters) by the characters in the Land Before Time series - appear in a flashback in The Land Before Time VII: The Stone of Cold Fire. They are the only Sharpteeth that appear in the film.
The Sharpteeth appear in Grandpa Longneck's story about why Pterano left the herd. When Pterano leads a fraction of the herd he convinced to follow him, they reach a dead end and are attacked by the raptors. Pterano is the only one able to stay out of harm's reach due to his ability to fly. Although some of the herd tries to fight back, it is implied that they are all killed, as none of them are ever seen again.
- It is possible that all of the members of the pack are relatives to one another.
