Walking with Dinosaurs 3D

A paleontologist named Zack takes his nephew Ricky and niece Jade on a fossil hunt. While alone, Ricky is met by a talking raven named Alex, who turns into an Alexornis. He tells him of a story set in the Late Cretaceous period, 70 million years ago. Patchi is the smallest in a litter of Pachyrhinosaurus hatchlings, and is often bullied by his older brother Scowler. Their father Bulldust is the leader of the Pachyrhinosaurus herd. Alex, who is Patchi's mentor, 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 take him away but is saved by Bulldust, resulting in Patchi having a hole in his frill as an injury which Alex claims that Patchi was "destined for greatness".
