Dinosaurs on space

The astronaut prevention

These Dinosaurs always feared the humans that landed on Mars to explore it so they did something, they dug a hole on the red sand and when they locate a spaceship they go under it and hide for the longest time possible, if one of them doesn't have time to hide they hide behind the big lumps that the red sand makes when there is a lot of sand, some astronauts don't explore the big lumps of sand that are way too far away where their spaceships usually lands, so Dinosaurs have space on the lump to hide.
