in mongolia, the temperatures are finally starting to decrease. the "troodon" run outside and start feeding on a "charonosaurus" corpse. soon, the "charonosaurus" follow. however, one stays near the protection of the cave. however, the dinosaurs are not safe yet. the ejecta cloud has caused a huge sandstorm. as it hits, the "troodons" are small enough to crouch for cover. but the "charonosaurus" are out in the open. the harder they struggle and the deeper they gasp for oxygen, the more sand fills their lungs, until finally, they can't breathe. it's hours before the winds die down. the last "charonosaurus", protected once again by the cave, finds that it's the last of the herd. but it's not the last remaining dinosaur in the neighborhood. the "troodons" were sheltered from the worst of the storm. they have survived.
