The Land Before Time XII: The Great Day of the Flyers is a 2006 animated musical direct-to-video film, and is the twelfth film in the Land Before Time series. It was released on February 27, 2007 by Universal Studios Home Entertainment.
Petrie is having a difficult time preparing for "The Day of the Flyers", an important day for all of the flying residents of the Great Valley, when all of the young flyers must participate in a very precise flying exhibition to prove that they are ready to fly with the adults. Always a nervous flyer, Petrie has even more trouble flying with his siblings in precise group formations — he's more of an independent, free-style flier. At the same time, a strange newcomer to the Great Valley has Littlefoot and his friends trying to help figure out just exactly what he is. Named Guido, a Feathered Flyer, he's the strangest looking creature any of the Great Valley creatures has ever seen, especially since he's covered with feathers, and has never seen another like himself. Cera is having her own troubles, as her grumpy father and his new mate, Tria, get ready to welcome a hatchling to the family.
All of these issues come together on the night before "The Day of the Flyers," when Guido starts to figure out what he is, inadvertently leading all of the gang on a perilous adventure into the Mysterious Beyond. They encountered a Spinosaurus which gives chase and tried to eat them. But Petrie, Guido, and the others defeat the Spinosaurus and they returned to the Great Valley.
