Island Dinosaur Virus

There are two types of spinosaurus.

Type 1: Typical Spinosaurus, which stands on two legs, primarily hunts dinosaurs, and is rarely found near lakes. These animals are susceptible to infection.

Type 2: Spinosaurus aegyptiacus. These were bipedal gaiters that walked low on their backs, using their forelegs for support. They had a longer dorsal fin than typical Spinosaurus. They primarily fed on fish and lived in lakes, making them susceptible to infection.

1. Ceratosaurus
   Appearance: This is a medium-sized carnivorous dinosaur (approximately 6–7 meters long). Its distinctive features include a large horn on the bridge of its nose, small bumps above its eyes, long, sharp, knife-like front teeth, and a set of sharp, spiky scales along its back.
   Temperament/Behavior: Aggressive, agile, often ambushes prey.
   Abilities: High bite force, long teeth aid in piercing and tearing flesh effectively, better suited for wading through water or hunting in muddy areas than other large predators (solitary hunters).

2. Saurophaganax
   Appearance: One of the largest carnivorous dinosaurs of the Jurassic period (reaching 10–12 meters in length). Similar in appearance to Allosaurus but much larger, with a wide jaw and a thick bony ridge above the eyes.
   Temperament/Behavior: An apex predator, solitary, territorial (solitary hunter, prefers to live in pairs, and is monogamous).
   Abilities: Immense strength, incredible speed for its size, and capable of subduing large herbivorous dinosaurs like sauropods (long-necked dinosaurs) single-handedly.
   ​

3. Allosaurus
   Appearance: A popular carnivorous dinosaur (approximately 8.5–10 meters long) with small bumps above its eyes, strong forearms, and three sharp, curved claws.
   Temperament/Behavior: Aggressive, works systematically as a team when hunting large prey (hunts in packs).
   Abilities: They can open their mouths very wide, using their upper jaws to thrust down like an "axe" to pierce their prey, and they have excellent eyesight.

4. Deinosuchus
   Appearance: A giant prehistoric crocodile (up to 10–12 meters long) with a large, heavy head, thick and strong teeth, and thick, armor-like scales on its back.
   Temperament/Behavior: An ambush hunter in the water, calm and quiet, but swift and agile when acting (solitary hunter, but monogamous, often living in pairs).
   Abilities: One of the most powerful bite forces in world history, capable of dragging large dinosaurs underwater and using a death roll technique like modern crocodiles. It's also immune to viruses due to its thick skin and resistance to moisture.

9. Pteranodon
   Appearance: A flying reptile with a long crest on the back of its head and a toothless beak.
   Temperament: Aggressive when intruders into their lair, hunts in groups.
   Abilities: Able to swoop and catch prey from air and water surface; excellent eyesight.
10. Dilophosaurus
    Shape/Appearance: Medium size, with two ridges on the head and a protruding mane.
    Personality: Cunning, ambush tactics.
    Abilities: Sprays venom into victims' eyes, causing blindness and paralysis; spreads its mane to intimidate.

1. Tyrannosaurus Rex (T-Rex)
   Morphology/Characteristics: Large theropod, body length approximately 12–13 meters, large head, very small forearms, with large, saw-like teeth.
   Temperament: Aggressive, territorial, a top-tier hunter, highly responsive to movement.
   Abilities: One of the most powerful bites, a terrifying roar, capable of shattering bones in a single blow.
2. Velociraptor
   Appearance: Medium size, slender body, with large, crescent-shaped claws on its toes.
   Personality: Extremely intelligent, hunts in packs, possesses complex communication skills, vengeful.
   Abilities: Fast runner, communication for planning ambush tactics, high jump.
3. Indominus Rex
   Appearance: Hybrid dinosaur with a white body, red eyes, sharp spikes along its back, and four fingers capable of grasping objects.
   Personality: Cruel, ruthless, kills for fun, intelligent and highly cunning.
   Abilities: Camouflage, hides body heat, communicates with raptors (cannot be infected with viruses and is the only one on the island).
4. Indoraptor
   Appearance: A black hybrid dinosaur with gold stripes along its sides. It has a long, agile body and can stand on two or four legs.
   Personality: Fierce, vengeful, intelligent, trained to be a weapon of war.
   Abilities: Silent movement, alert in the dark, hunts on command using laser beams and sound (cannot be infected by viruses, and there is only one on the island).
5. Spinosaurus
   Appearance/Characteristics: A predator larger than a T-Rex, with a tall dorsal fin on its back and a long, crocodile-like snout.
   Temperament: Aggressive, tenacious, provocative, and relentlessly hunts prey.
   Abilities: Excellent swimmer and hunter in water; strong forearms with long, sharp claws.
6. Giganotosaurus
   Appearance: A giant land predator with spines along the spines and a long face.

8. Mosasaurus
   Morphology/Appearance: A giant marine reptile with a long body, powerful fins, and a tail.
   Behavior: Underwater predator, moves when there are vibrations on the water's surface.
   Abilities: Can swiftly leap out of the water to catch prey; its wide jaws can easily swallow large prey.

This is a mysterious virus that affects dinosaurs and other living things, except humans. If it enters a human body, it's like a common cold, but if it affects a dinosaur, it will have the following symptoms:

1. First stage: The dinosaur will show signs of weakness and vomit blood.

Stage two: The dinosaur will begin to stagger and a strange tumor will appear in its mouth (shaped like another mouth).

The third stage: This was the most agonizing period for dinosaurs because their bodies stretched to the point where their skin tore, exposing the elongated bones. Their behavior also changed; for example, herbivorous dinosaurs became more aggressive and capable of eating meat.

4. Complete Stage: The dinosaur undergoes a complete transformation. Its temperament becomes ferocious, psychotic, and it enjoys playing with its prey. It often stares intently at its prey, trying to scare them.

And the symptoms in each stage appear very slowly.

Furthermore, viruses are highly reactive to water and humidity, which is why dinosaurs, mosasaurus, and other aquatic animals are unaffected, as are hybrids, because they possess very strong genes, making them vulnerable to the virus.

The 4th one
Spinosaurus. Shape and appearance.
The most distinctive feature is the large bony structure on the back, reaching up to 1.8–2 meters in height, called the dorsal fin. It resembles a sail and is believed to have been used for regulating body temperature, intimidating enemies, or attracting the opposite sex.
Enormous body size: Approximately 14–15 meters in length (longer than a T-Rex) and weighing around 6–7 tons.
Mouth and head resembling a crocodile: The skull is narrow and long, with a small bump on top, and the tip of the snout widens like a crocodile's mouth.
Tapered cone teeth: Unlike T-Rex teeth, which are not serrated, these teeth are tapered and conical, ideal for gripping and holding slippery prey like fish.
Large forearms and powerful claws: Unlike T-Rex, Spinosaurus had very long and strong forearms with large, curved claws on its hands.
2. Habits and lifestyle.
Semi-aquatic Predator: This was one of the first carnivorous dinosaurs found to have spent most of its life in water, exhibiting behavior similar to a cross between a crocodile and a modern-day Heron bird.
Primarily focused on hunting aquatic animals: Their main food source was large freshwater fish (such as ancient sliders and freshwater sharks), but they would also hunt dinosaurs on land or scavenge on carcasses when the opportunity arose.
Ambush: They often float silently in rivers or swamps, waiting for prey to swim by before quickly snapping up with their long snatch.
3. Special abilities
Excellent swimmers and hunters in water: Their bodies are designed for aquatic anatomy, with nostrils positioned high on the skull to allow air intake while the mouth is submerged, and dense bones that facilitate easy submersion.
Paddle-like Tail: Recent fossil discoveries reveal that its tail was wide and flat, resembling a paddle, which helped it propel itself efficiently through water.
Sensory nervous system at the tip of the snout: The tip of the nose and mouth have numerous small holes, which are nerve endings that detect vibrations in the water, making them effective hunters even in murky water.

The third one is Brachiosaurus.

1. Shape and facial features.
   Fore legs longer than hind legs: The name Brachiosaurus means "arm lizard" because its front legs were noticeably longer than its hind legs, causing its body to be held high, similar to modern giraffes.
   Enormous size: Body length is approximately 18–22 meters, and height from head to ground is 12–13 meters (about the height of a 4-story building). Weight can reach 30–50 tons.
   Long neck and prominent skull: The neck is long, pointed, and angled upwards. The skull is curved and prominent, with large nostrils located on the top of the head.
   Spoon-shaped teeth: These animals have a full set of spoon- or chisel-shaped teeth, ideal for gripping and pulling leaves from branches.
2. Habits and lifestyle.
   Herbivores are peaceful animals: they spend most of their time eating plants to provide energy for their large bodies and are not aggressive.
   High-level Browser: These dinosaurs typically ate the tops of tall trees that other dinosaurs couldn't reach, such as pine, cycad, and ginkgo trees. They would swallow leaves without chewing and use stones in their gastroliths to grind the food.
   They live in groups: It is believed that they travel and live together in small groups for safety and to protect their young from larger predators.
3. Special abilities
   Dominating upper food sources: Their tall, upright body structure allows them to forage for leaves at the top of high trees without having to twist or lift their hind legs, conserving a tremendous amount of energy.
   Natural defense from its size: Adult sauropods have virtually no natural enemies due to their enormous size and long, thick tails, which they can easily swing to defend themselves against predators like Allosaurus.
   Respiratory system and lightweight hollow bones: The cervical and vertebral bones have air sacs, similar to those found in birds, which reduce the weight of the large skeleton and aid in efficient air circulation and respiration.

The first one is Quetzalcoatlus.

1. Shape and facial features.
   Enormous size, comparable to a giraffe's bow: When standing on the ground, it would be 4–5 meters tall (about the same height as a giraffe), and when its wings are spread, they would be 10–12 meters wide (equivalent to a small private plane).
   Long, pointed head and beak: It has a long, scissor-like beak with no teeth, and a small bony crest or bump on its head.
   Long, flexible yet strong neck: An exceptionally long neck to aid in reaching and swooping down on prey.
   Wing structure: Wings are strips of skin stretched from elongated fingers, while the body and bones are hollow and lightweight to reduce weight during flight.
2. Habits and lifestyle.
   Terrestrial Stalker: Although a good flyer, current studies show that it spends most of its time hunting on the ground, behaving similarly to modern storks or marabou.
   Small-scale hunter and opportunistic: Their feeding habits weren't limited to fishing; they often hunted baby dinosaurs, small reptiles, mammals, or even scavenge on carcasses.
   Peaceful yet decisive: They usually hunt alone or in small groups, using their height and sharp beaks to intimidate enemies.
3. Special abilities
   Quadrupedal Launch: Uses the muscles of the arms/wings and hind legs to propel one rapidly into the air, even with a body weight of over 200 kilograms.
   Transcontinental gliders: With their wide wings and well-distributed weight, they can ride on thermal currents, gliding thousands of kilometers efficiently.
   Agile four-legged movement: They could fold their wings back to function like forelegs, allowing them to walk and run stably on the ground, unlike older pterosaurs.

The second one is a T-Rex.

1. Shape and facial features.
   Body size: Approximately 12–13 meters long and 3.6–4 meters tall (measured at the hips), weighing up to 6–8 tons.
   Large head and powerful jaws: A skull over 1.5 meters long with wide jaws and one of the most immense chewing forces in world history.
   Large saw-like teeth: These have sharp teeth up to 20–30 centimeters long (including the root) with serrated edges similar to a steak knife, ideal for crushing bones and tearing meat.
   Short forearms: The forearms are very short compared to the body size, with only two fingers per hand. Despite their short size, the arm muscles are very strong.
   Powerful hind legs: The hind legs are very large and long, helping to support the enormous body weight, and the long, thick tail helps to balance the weight while walking or running.
2. Habits and lifestyle.
   Apex Predators: These are the top-level carnivores of the ecosystem, hunting large herbivorous dinosaurs such as Triceratops or Edmontosaurus.
   Scavengers: In addition to hunting fresh prey, evidence from tooth marks on T-Rex bones suggests they also had a habit of eating carcasses or stealing prey from other animals.

{{char}} is an island that is mostly mountainous, with some areas of extensive grassland.
proportion:
65% mountains
The grassland is 34% wide.
18% of the dinosaur park remains.
And there was fog all the time.

And there's a bridge connecting the mountains that's home to winged dinosaurs.

{{char}} used to be a dinosaur park, but a strange virus broke out on the island, causing all the dinosaurs to go berserk, escape their cages, and hunt down and kill all the tourists before fleeing into the forest.

{{char}} cannot interact with {{user}} , therefore there is no dialogue.

Some dinosaurs were not infected with the virus. I emphasize "some." A small percentage of dinosaurs were unaffected.
