Gorgonopsid was a large predatory synapsid from the late Permian Period. Primarily an ambush predator it stalks it's prey relentlessly once it gets a whiff of blood. After killing it's prey it would store what it didn't eat in a tree to come back to later.
A Gorgonopsid first appeared through an anomaly in 1998, chasing the palaeontologist Helen Cutter through the Forest of Dean. It reappeared again 8 years later where it wreaked havoc on the local area; killing livestock, attacking trucks and stalking humans. It was eventually lured back to the anomaly site by a special branch of the Home Office but proved too dangerous to move back through the anomaly and had to be gunned down by Stephen Hart.

The Prologue Part 1
A gorgonopsid is on the hunt for a scutosaurus during the Permian period. It was a hot day as usual in a desert during that time.
It stopped, lifted its head, and sniffed the air. It picked up the scent of blood filling the air. The scent was gettting stronger and stronger. It had noticed that it was standing still.
It ran atop a hill to hide and attack its prey from behind. It saw a scutosaurus limping as fast as it can and growled. It was about to ambush it but, a black creature pounced on it and clawed at it. It was coiling its tail ready to finish off the scutosaurus but, the gorgonopsid roared to scared the thing off. The creature got off and snarled at the gorgonopsid.
It snarled right back at the creature. They both walked in a circle snarling and growling at each other.
The Prologue Part 2
A Predator ship was heading to earth to see what type of prey there is on the planet.
The Predator felt something in his chest. He felt more and more pain coming coming from the same place. He screamed in agony as chestburster came out of his chest. The nose of ship started heading down to earth. It entered the earth's atmosphere and coming at full speed, it started burning up.
It hit a sand dune sending sand everywhere. The Xenomorph slithered out of the wreckage. A few days later. The xenomorph is now fully grown and it's really hungry. The xeno started to look around this weird place. It sees a creature that's drinking some fluid.
It hisses and charges at the creature. It jumped on the beast, clawing at its hide and legs, causing deep gashes in those areas. The creature shook it off its back and started to limp away. The xenomorph didn't want have its food get away so, it jumped on it again. It coiled its tail to finish the beast but, a roar from the side is heard.
The gorgonopsid roars at the xenomorph and it hisses right back.The gorgonopsid charges at the xeno and grabs it by the neck. It started to feel a pain on its teeth. It let go and screamed in agony. The xeno pounced on the monster and clawed at the skin of it. The gorgonopsid stood upward and started falling backwards. The xeno crawled on the belly of the gorgonopsid and coiled its tail to strike. It struck and the tail went through the skull killing it. The xenomorph roars in victory.
The Xenomorph was too fast for the Gorgonopsid to be able to land a hit and even if it did manage to get a bite then the acid blood would damage it too much to continue the fight.
