Littlefoot

Littlefoot is the main protagonist of The Land Before Time franchise. He is a young brown Apatosaurus which is called a "Longneck" in the films.

He is followed by Cera the Triceratops, Ducky the Saurolophus, Petrie the Pteranodon, Spike the Stegosaurus, Chomper the Tyrannosaurus, Ruby the Oviraptor, Ali the girl Apatosaurus, and Guido the Microraptor. Due to his skill at befriending others, he is also friends with many other creatures, although his friendships with dinosaurs and other animals outside his species is often viewed as a taboo, as many of the dinosaurs practice racial, or species based, segregation, which is based upon the days of racism in America.

The character has been received very well by critics and become a favorite among Land Before Time fans, and has been featured in much of The Land Before Time-related merchandise, along with being referenced frequently in the media.

Trivia

 * As Littlefoot is shown to hatch right after Cera, he is five years old at the time of the first movie.
 * Littlefoot appears to have a problem with losing those he cares about. First, he is distraught about his mother's death, blaming, at various times, both himself and his mother over it. He also goes into the Land of Mists and risks his life to save Grandpa Longneck, despite being advised not to by his grandparents and the Old One. Later, he goes to the Fire Mountain and risks his life to save his father Bron.
 * Littlefoot is called a Brontosaurus on the original video cover for the first film, and then on the clamshell case he is called a Brachiosaurus. He was also called a Brachiosaurus at Rotten Tomatoes.com and at Movies.com.
 * In the media, Littlefoot is alternatively referred to as an Apatosaurus and a Brontosaurus.
 * Prior to 2015, Brontosaurus was considered a species of Apatosaurus, though an extensive study that was published in 2015 resulted in A. excelsus and two other species of Apatosaurus being reclassified as species of Brontosaurus, due to the research concluding that the two are different, distinct genera of sauropods.
