Chapter Three sees the Allosaurus watching a herd of sauropods; however, a sudden rainstorm causes him to decide to retreat to his new lair, a small cave. The main storyline of this chapter occurs in the skies overhead. After a long chase, a green pterosaur is attacked and killed by a group of three black pterosaurs; it seems the two groups are rivals for prey or territory. A lightning strike causes a fire in the cliff face den of the green pterosaurs; one of them, in a panic, winds up falling off the cliff to its death.
