A second Sauronithoides appears however, which forces the Charonosaurus to flee. A Saurornithoides steals an egg from one of the nests, but is soon confronted by the enraged mother. In what is now Mongolia, a herd of Charonosaurus reside by a watering hole, where the females lay their eggs. Most of the eggs are destroyed but some survive, buried under the soil. Afterwards, a magnitude 11 earthquake cripples the rest of the herd before the blast wave arrives and finishes off the last of the Alamosaurus. Moments later, burning debris come raining down from the sky, crushing many Alamosaurus. Hundreds of Alamosaurus are burned alive. The explosion heats the air temperature near the site to hundreds of degrees. The asteroid hits the Earth in Mexico, causing a big explosion and sending debris shooting through the air. A female lays a clutch of eggs as an asteroid enters the atmosphere. Meanwhile, in Mexico, a herd of Alamosaurus are roaming the plains in search of food. Working together, they bring down the Triceratops and eat it together. Two T.rex hear the commotion and close in to attack the loser. Only one hatchling survives the attack.Ī male Triceratops loses a fight for mating rights against another male Triceratops.

It finally takes off just as the father bites its foot, though the pterosaur manages to break free of his jaws by pecking at his eye and then flying away. rex repeatedly lunges and tries to kill it. The pterosaur is forced to flee when the enraged father arrives, trying to take off but its huge wings prevent it from flying in the forest. Meanwhile, the father Tyrannosaurus is hunting for prey in the forest when his acute sense of smell alerts him to the intruder and runs back to the nest. The pterosaur then flies down and consumes several young babies. In the Pacific Northwest, a Quetzalcoatlus is soaring above the valley during a rain storm when it spots an unguarded Tyrannosaurus nest. These models were placed upon different backdrops most of the time than those used in Clash of the Dinosaurs. The same Tyrannosaurus rex, Triceratops, Ankylosaurus, and Quetzalcoatlus models were also used. The Deinonychus model was used for Saurornithoides (rather inaccurately, as Saurornithoides was slenderer than Deinonychus), and the Sauroposeidon model was used for Alamosaurus (even though Alamosaurus had different proportions than Sauroposeidon). The Parasaurolophus model was used for Charonosaurus even though the legs of Charonosaurus were shorter than those of Parasaurolophus. The dinosaur models created for Clash of the Dinosaurs were reused for this program.

The documentary was released on Augand narrated by Bill Mondy. It portrays the Alvarez hypothesis as the cause of extinction.
