Polar Nightmare

It is dark in between Australia and Antarctica, 254 million years ago. It is winter, and five months of winter has begun. Aurora australis sweep in the air, providing all light and no warmth. A giant long furred gorgonopsid walks across the endless snowy landscape. He roars, and steam blows out of his mouth. He is an Australogorgon, and the top predator of this forgotten land.
It is now spring, and this area between Australia and Antarctica is now melted and a wide area of blue water with looses pieces of ice float. And with it, life has retreated. At the edge of a rocky shore, the sky is glooming. The Australogorgon is showing off his lack of intelligence. He rushes at the waves, but when they crash and moves towards him, he scoots back and snaps at it. He then backs away after playing with the waves. He moves back further into the icy plain and begins to look for food. In these snowy plains, are some burrowing animals.
There are Auroracephale. These animals are in fact very close relatives of Diictodon, but lack the spikes, and instead have incredibly thick fur to keep warm. They also lack tusks and have a slightly longer, curved beak. They are waking up from their hibernation. The Australogorgon looks about the landscape. A herd of larger furred Ornistrosaurus are walking in the distance. However, as one member has spotted him, he looks back down onto the ground. He sniffs the ground and finds the location of the Auroracephale. The Auroracephale's burrow's begin to shake, and snow falls down. The Australogorgon is slamming his front paws into the ground, trying to get to the dicynodonts. They run, but he is smart. He finally breaks the ground and snaps an Auroracephale from the ground, then eats it. The others are gone. He'll go hunting the Ornistrosaurus.
Elsewhere, in the mountainous regions, a predator is stalking its prey. A few Pterognathus are hopping about. These cynodonts are in fact similar to flying-squirrels. One goes to a steep hill, and leaps off a rock, and glides down the hill. But he is prey. From above, is a Glossognathus. She has the colour of a snow leopard, and her coat is like a snow leopards, especially the furry tail. She is waiting for the Pterognathus to come close. As the cynodont hops further up, the Glossognathus is shaking in anticipation. Then, she leaps, but the Pterognathus turns and rushes down. A chase ensues. Then, the Pterognathus goes to the steep rock and glides off into the fog. The Glossognathus skids to a stop. She'll have to try again later.
Back down, is a rocky area with a river. And so the Ornistrosaurus drink. The Australogorgon walks to the wide river and they give him a wide berth. He has recently killed an Ornistrosaurus and eaten it. He drinks the cool river water to wash off the dead Ornistrosaurus. He then walks away, goes to the base of the mountain, and rests there. These rivers, are full of predators.
An Ornistrosaurus sees his reflection in the water and puts his arm out to touch it. Suddenly, an amphibians mouth lunges out and snaps at the arm, but the animals back away. The amphibian slips away. He is a Koolaspondylus. His wide mouth and gigantic size of 8 metres, he is the top predator of the rivers.
Summer takes hold, and most of the snow melts. On the rocky plains, some burrowers trot. They are Antarctocynodon, stoat like cynodonts. They are in stiff competition with the Auroracephale, and attempt to take over their burrows. However, when, they try to fit their bodies in, the dicynodonts kick dirt into their faces and they run off. These cynodonts won't return here.
Back in the mountains, the female Glossognathus is waking up in her den with her mate. Her mate is another female. A recent survey shows that nearly 20% of all pairings are that of the same sex. They groom themselves and each other, before our female is sent on a rare mission. To go down the mountain and hunt the Auroracephale.
Down at the rocky plains, our male Australogorgon is facing off against a rival who has entered his territory. To avoid injury, they rear up and swipe. The rival backs down and our male can rest. The female Glossognathus is now down. Her thick snow leopard coat makes her stand out. She has something that even the Australogorgon doesn't. External ears. But, as it turns out, they are vestigial, so they actually aren't external ears. She then begins to hunt the Auroracephale. They have just laid their eggs. After a while of hunting, the Glossognathus has eaten two Antarctocynodon, and then runs back up the mountain with one in her mouth. When she reaches her den, she feeds her mate.
But the endless sun doesn't last forever. Soon, rains come, and so the animals have to find the odd shelter in the plains. The Koolaspondylus now emerges out of the river and sits on the bank, enjoying the rain hitting his soft body. In the mountains, instead of heavy rain, there is heavy snow. The Glossognathus are safe in their den. One of them has recently laid a clutch of five eggs. They have either stolen the eggs, or mated with a male. This change in the weather signals the end of summer. Then, comes, the first night in four months.
Now, the animals are getting prepared. The Australogorgon is feeding on a recently killed Ornistrosaurus. But he is not going to stay here. The ice that connects Antarctica and Australia returns, covering up the ocean. Now, the Australogorgon leaves, as it begins to snow. After a few days of walking on the ice, he sees a large section of open water. It should be closed. This shows the climate is changing. He spots a few ice bergs and leaps onto one. However, he struggles and eventually collapses into the frigate waters. He looks down into the deep blue below. Here, lurk predators, and the bottom of the ocean is more than several miles deep. A scary thought. He surfaces, and sees the ice berg he just fell off of rushing towards him. He dives and swims. He nearly escapes, but the iceberg smacks into his side and he briefly looses control. Now, it is night and he struggles to swim. And the morning will come in five months. He sees just the faintest colour in the sky, the auroras, which is obscured by the clouds and snow.
He breathes, and fog comes out. In the mountains, our Glossognathus and he mate look from their den at the auroras. Their eggs have hatched. The pups squeak, and they both retreat, but our female lingers for a brief moment.
The Australogorgon barely swims out of the water and shivers severely on the bank. Then, he collapses and holds his head up. However, he struggles, and his head collapses. He is in shock and will die of hypothermia.
The winter goes on. Our female Glossognathus is looking at the sky again, except this time, there is no aurora. Then, her five pups look at the edge and peer at the sky. One tries to exit the den, but her partner arrives and scoops them all back into the den.
The Auroracephale are hibernating, but most, won't wake up in the spring.
Ice has covered the dead Australogorgon. He is sticking firmly to the rocky ground. Another Australogorgon, during the wild blizzard, walks towards his carcass and sniffs it. He then begins to bite and try to rip a chunk of flesh out, but it is too frozen. He will have to find other food. The winter goes on.
Food resources and becoming of great need for the Glossognathus. The pups are hungry, and her mate has no milk. Our female leaves to hunt in the dark. Her long whiskers and big eyes help her navigate in the dark. She spots an Antarctocynodon popping out of his burrow to hunt. She begins to stalk him. The cynodont is hunting a very rare polar insect: blattoptera. He gently approaches it, and the Glossognathus gently follows him too. Then, a single pounce, and she has the cynodont in her jaws. She rushes up to her den and disappears.
Under the massive block of sea life, life, still stirs. Some trilobites have large eyes with eyeshades, and are perfectly active in the winter months. They actually spend most of their time hanging under the ice, feeding on small animals there. Sometimes, they free float and swim similarly to anomalocarids. But below are beautiful predators. A rare eurypterid swims below. He is three meters long and bizarre. He has gigantic Megalograptus-like arms, and a Pterygotus like tail. And the ornament at the end of the tail is blue and light blue, and glows in the dark. These dots actually spread across the animal. A bioluminescent eurypterid. He tries to take a swimming trilobite, who quickly swims away. He then finds one clinging onto the ice. He briefly lets go and wiggles his legs, as to not get frozen. Sometimes, ice grows outwards, and in one several trilobites are trapped. As the trilobite wiggles, the eurypterid comes out and grabs the trilobite. Another eurypterid comes and finds an area where ice is loose. He leaps out onto a tiny iceberg. He uses his back fins to propel the ice berg forward. He unknowingly made the first boat. He then slips off into the water, then shoots onto the rocky shore. He approaches what os left of the dead gorgon. He is used to crunching tough shells, and so is able to crack the ice and scavenge off the dead predators remains. But a male Glossognathus sees this as an opportunity to kill and eat a eurypterid. He rushes forward, but the eurypterid turns and arches his tail. The stand off isn't long, and the brief fight ends with the Glossognathus grabbing its tail and dragging it away to eat.
Finally, winter releases her icy touch on the landscape. Life, can resume back to normal. The den of the Glossognathus is covered in snow. Our female is walking up the snowy hill and stops, looking at her hidden lair. Then, a Glossognathus pup emerges. Then another, and another until five young step outside for the first time. They play, slide down the hill, and what ever else pups do. Our female's mate emerges out, and they follow the young, and make sure they don't go too far away. One sees a Pterognathus who leaps away. They have a long way to go before they know the world.
