Original Sharptooth


There are many Sharpteeth, or carnivorous creatures in The Land Before Time. They are usually the main antagonists of the movies, sequels, and series, while a select few others, such as Chomper, are protagonistic. The most common voice for Sharpteeth is Frank Welker. Others include Danny Mann, Pete Sepenuk, and Rob Paulsen.

This is a list of the various Sharpteeth seen throughout the series, in order of appearance.

The Time of the Great Giving

Unquillosaurus pack - These were the first known Fast Biters to appear in the franchise. During the introduction of the third, the scene about evolution fades from the Devonian to the Mesozoic, where an Unquillosaurus is drinking from a river. The individual then notices its pack members coming towards it and thus follows them over the river.

Dromaeosaurus pair- Also during the introduction of the film, two Dromaeosaurus (one blue, another brownish) are seen surrounding a Chasmosaurus. The brown one leaps at the ceratopsian before the scene fades to the Great Valley. It is unknown what became of any of them.


Velociraptor from III

Velociraptor pack - When the dinosaurs in the Great Valley came to the Mysterious Beyond to get their water back, they were attacked by a pack of four Velociraptor. While they fought back, one was knocked out by a rock and possibly killed, while the remaining three were separated from the leafeaters by a river.

Journey Through the Mists

Ichy and Dil - An Ichthyornis and Deinosuchus who side with each other to catch prey. The two don't like each other much, but stay together because of their handicaps: Dil's being sight and Ichy's being size. Though they are possibly sharpteeth, they are categorized in a different term.

Tyrannosaurus - A Tyrannosaurus (resembling Chomper's father and the Sharptooth from the first film) was seen briefly at the beginning of the film chasing a group of Dryosaurus.

Hydrotherosaurus - A large male Hydrotherosaurus attacks Dil after she bumps into him, chasing her away. He is one of the few Sharpteeth who didn't chase after Littlefoot and his friends.

Chomper's Mother - Chomper's mother appears again along with her mate. She is very caring towards her son, and can be very defensive, roaring right behind Littlefoot to make sure Chomper is safe.

Although the two Tyrannosaurus are not the main antagonists, Chomper tries to help keep his friends safe from them.

Sharptooth Flyer - A carnivorous female Pterodactylus that tries to feed Ducky to her hatchlings.

T-rex vs. Giganotosaurus

Giganotosaurus vs. Papa Sharptooth

Plated Sharptooth - A Giganotosaurus who appears on the same island as Chomper's family.

He may have crossed the land bridge connecting to the island, and likely did not live there.

Gray Tyrannosaurus - A gray Tyrannosaurus that lives in a swamp. Cera, Ducky, Petrie, and Spike at first mistake him for a boulder and sleep next to him. He wakes up when the children start talking and chases them. He later attacks the characters with two other Sharpteeth.

Journey of the Brave

Featherhead Sharpteeth - A pack of Yutyrannus that attack the children at points in the film. Though their attempts to eat the children are initially foiled due to the pair being unable to find the five juveniles, they eventually become active threats after they mistakenly dispose of their defenses. They are ultimately defeated during a spat on a high ledge; the pale green individual being tripped off of a small cliff, and the olive one being smashed by a multitude of boulders and frightened away.

Horned Sharptooth - A Carnotaurus that appears as the more dangerous antagonist of the film. He briefly appears to attack Cera, Ducky, Petrie, and Spike while they are separated from Littlefoot.
