Burning rock

Prologue (before this was clash of the bio titans in broodmother)

A young survivor wearing desert cloth armour readied his bow, he was hunting microraptors in the badlands of scorched earth, and desperately needed food. He fired an arrow, which struck a microraptor, killing it on the spot. He smiled as he picked up the body and put it in a bag, he was ready to go back home when a sharp spine hit his arm, causing him to yell in pain. The spine had come off a thorny dragons tail, which meant he was being hunted. He spun around and fired an arrow at the attacking thorny dragon, scaring it and making it run away. But then he heard a roar, and turned around, he let out a scream, which stopped quickly as the creature tore apart the survivor, sending blood and pieces of flesh in every direction.
