Walking with Dinosaurs S01E04 - The Pack

Seventy-one million years ago lived a teenage Albertosaurus - a faster, nimbler relative of T. rex. She had to earn her place in a deadly, ferocious pack or risk starvation.

Today, palaeontologists in western Canada are unearthing her remains, allowing us to imagine her story. Based on real-world evidence, stunning VFX recreate her encounters, from hunting pterosaurs to fighting the dominant matriarch and battling for survival in the brutal late Cretaceous world.
