In a nearby river there is a herd of Parasaurolophus drinking water. The female Daspletosaurus walks slowly. and approaches a sub-adult male Parasaurolophus, the young dinosaur strayed too far from its herd and is now in danger but does not know it. The female Daspletosaurus charges at her prey and grabs the subadult Parasaurolophus by the tail, breaking a vertebra of the young Parasaurolophus. Luckily for this young male, an adult runs into the area and hits the female Daspletosaurus with his head, other adults get closer quickly to try to scare the female. The female decides to let the young parasaurolophus go, because an angry parasaurolophus herd is not something she wants to deal with. She goes into the forest and founds a dead styracosaurus that died from old age, she brings her three young to the corpsee so they can finally eat.
