Littlefoot's Mother (a.k.a. Mama Longneck, as she is referred to as by fans,), voiced by Helen Shaver, is a character in The Land Before Time film series. She is an Apatosaurus; one of many sauropods referred to as "Longneck" in the franchise, and the mother of the main protagonist Littlefoot, the wife of his father Bron, and the daughter of Grandma and Grandpa Longneck. She, like her parents but unlike most of the dinosaurs in the first Land Before Time movie, is not bigoted towards other species, although she will generally avoid those of other species because things have been done that way for a long time.
She plays a major role only in the original film, during which she is killed by the original Sharptooth (the scene for which the character is most famous), but she is referenced several times in later films.
In The Humanization Series, She Was Revied By Michael And Everyone Now Knows The Name, Rose. Rose The Longneck.
