Cretaceous creeps pt1

This is my first story of this series so expect it to be bad

Three mantis’s roam through the desert plains in search of shelter “when are we going to find a home” says the 2 children behind the mother. “When we get there, now shut it!” “But we could have stayed in our original home.” Says the younger one “the original home is inside the wyverns territory, we were constantly threatened by them.” The 2 kids sighed wondering if they would every find a home. Suddenly the ground starts rumbling, the mantis’s start frantically looking around. Sand burst up from the ground and the mantis’s go flying. A ferocious death worm emerges from the earth and sounds a terrible screech. The mantis’s scatter into rocks and debris, desperately trying to evade the worm. The worm thrashes rocks, knocking out 1 mantis and trapping another. The mother desperately tries to help her children but to no avail. The worm seems to get closer and closer ready to strike until- it’s gone, the dunes Lie dormant again. The mother falls and cries to what just occurred.
