This is a list of the various Sharpteeth seen throughout the series.
Sharptooth - A dark green Tyrannosaurus; the main villain of the first film. Is inadvertently blinded in one eye by Littlefoot. Kills Littlefoot's mother. Chases the main characters until they push a huge rock on him, causing him to fall into a lake and presumably drown.
Tyrannosaurus - A Tyrannosaurus appears at the beginning of the movie during the narration. It bears resemblance to the original Sharptooth and Chomper's father.

Ichy and Dil - An Ichthyornis and Deinosuchus who side with each other to catch prey. The two don't like eachother much, but stay together because of their handicaps: Dil's being sight and Ichy's being size. Though they are possibly sharpteeth they catagorized in a different term.
Cryptoclidus - A large Cryptoclidus attacks Dil after she bumps into it, chasing her away.

Plated Sharptooth - A Giganotosaurus who lives on the same island as Chomper's family. Unknown to them at first, he chases the main characters and later attacks Chomper's parents when they try to protect him.
"The Biggest, Meanest, Most Ferocious Sharptooth Ever" - A legendary Sharptooth that the Lone Dinosaur defeated. His teeth are said to be the same ones around the neck of Saurus Rock..

Postosuchus - These quadrupedal Sharpteeth inhabit a swampland.
Large Belly Dragger - A Sarcosuchus that lives in a marsh attacks the Longneck herd that migrates through, almost eating Littlefoot, but is crushed by Sue. Later, Littlefoot's friends also face off against it, and it almost eats Petrie. Like Ichy and Dil this creature is dubbed by a different term.
Postosuchus - One appears in the introductory sequence of the film, roaring on a cliff, but dying of apparently natural causes.
Baryonyx Pack - A pack of Baryonyx that attack the children when they are trying to help Loofah, Doofah, and Foobie escape. The pack supposedly were killed when they stood on the edge of a cliff and it shattered under their weight, causing them to fall.
