"...[A] special-effects wow of a sequel....[With] educational content, but also thrill-heavy scripts..."
This nature documentary uses animation and hours of researched facts to attempt to recreate the age between the extinction of the dinosaurs and the dawn of the modern human. Among the most intriguing creatures are giant flightless birds, the saber-toothed tiger and the many predecessors to human beings. An incredible document of beasts generally passed over in evolutionary studies with amazing animation.
