In this chapter, Leyster and Lai-tsz observe the rare supersauropods called oneirosaurs in the late Cretaceous period and discover that these dinosaurs communicate using infrasound, a low-frequency sound beyond human hearing. The chapter also details the preparations and departure of a rescue party, including Leyster, Tamara, and Chuck, who set out to aid injured companions Daljit and Jamal, highlighting the challenges of navigating prehistoric terrain and the dynamics within the group.
In this chapter, the expedition team encounters a herd of geistosaurs, large mute hadrosaurine dinosaurs, and must remain still to avoid provoking them. They learn from a phone call that infrasound communication among dinosaurs has been detected, confirming interspecies communication hypotheses. The chapter explores the challenges of survival in the Cretaceous period, the gradual loss of modern technology, and scientific debates about dinosaur behavior and extinction events.
