Plot

A paleontologist named Zack takes his nephew Ricky and his niece Jade on a fossil hunt in Alaska while their parents are on vacation in Europe. While alone, Ricky encounters an anthropomorphic raven named Alex, who then transforms into a prehistoric ancestor, Alexornis. Alex tells Ricky of a story set in the Late Cretaceous period, 70 million years ago, about his best friend Patchi. Patchi is the youngest and smallest in a litter of Pachyrhinosaurus hatchlings and is often bullied by his older brother Scowler. Their father Bulldust is the leader of the herd. Alex, who is Patchi's mentor, protector, and teacher, tries to help Patchi impress a female Pachyrhinosaurus named Juniper, but her herd migrates south without him. Patchi is also attacked by a Troodon, which attempts to eat him, but he is saved by his dad, resulting in Patchi having a hole in his frill as an injury which Alex claims that Patchi is "destined for greatness".
