What is what kind of dinosaur is ducky?

Ducky is a character from the animated film "The Land Before Time" series. She is a Parasaurolophus, which was a genus of herbivorous dinosaur that lived in North America during the Late Cretaceous period. Parasaurolophus is known for its distinctive crest on its head, which some scientists believe was used for communication or as a resonating chamber for making sounds. Despite its size, Parasaurolophus was a relatively harmless dinosaur that primarily fed on plants and vegetation. In "The Land Before Time" series, Ducky is depicted as a kind and compassionate young dinosaur who is known for her catchphrase, "Yep, yep, yep!"
