Dinosaur Roster

A heavily built ornithopod with a long, stiffened tail used for balance and defense, the Tenontosaurus is one of the island's most frequently hunted large herbivores - and one of the most alert. Historically preyed upon by pack hunters, it has evolved sharp senses and a strong flight instinct. Its tail can deliver a punishing swing to anything that gets too close.

One of the largest herbivores on the island, the Edmontosaurus travels in loose herds through open floodplains and river corridors. Its size makes it a tempting but dangerous target. Docile when unprovoked, but capable of delivering crushing kicks and full-body charges when cornered.

A lighter, more agile relative of the larger iguanodonts, the Mantellisaurus survives by staying alert, mobile, and difficult to corner. Often found browsing forest edges and open clearings, it relies on speed and awareness rather than brute strength.

With a spiked frill and forward-facing horn, the Styracosaurus is a defensive herbivore that turns intimidation into survival. It is smaller than some of its ceratopsian relatives, but far more aggressive when threatened.

Armored from skull to tail, the Ankylosaurus is a walking siege wall built to outlast anything foolish enough to bite it. Its heavy plates and low body make it difficult to injure, while its massive tail club can punish predators that get too close.

Light, fast, and built for open ground, the Gallimimus survives by seeing danger early and leaving it behind in a cloud of dust. It is not made for brawling, but its speed and agility make it one of the hardest animals on the island to catch.

The Lokiceratops is a striking ceratopsian known for its dramatic frill horns, giving it one of the most recognizable silhouettes among the island’s herbivores. Built for defense and display, it can hold its ground against predators with powerful charges and dangerous head swings.

Known for its strong nesting behavior and herd-focused lifestyle, the Maiasaura is a social herbivore built around awareness, protection, and survival through numbers. It is not the most heavily armed animal on the island, but a herd of Maiasaura can be difficult to isolate and even harder to break.

Small, quick, and easy to underestimate, the Microceratus survives by staying low, alert, and close to cover. Its tiny frill and beak give it a bold little silhouette, but speed and awareness are its real defenses.

The Padillasaurus is a towering long-necked herbivore that moves through forests and open valleys with slow, deliberate confidence. Its size protects it from most predators, but young or isolated individuals can still become targets.

Known for the long crest sweeping from its skull, the Parasaurolophus is a social herbivore often heard before it is seen. Its calls can carry across forests, floodplains, and river valleys, helping herds stay together and warning others of danger.

One of the largest hadrosaurs to ever walk the island, the Shantungosaurus is a towering herbivore with enough size to make most predators reconsider their plans. It travels through floodplains, forests, and open valleys in search of heavy vegetation, relying on bulk, herd movement, and powerful defensive strikes to survive.

The Stegosaurus is a heavy defensive herbivore marked by towering back plates and a tail armed with deadly spikes. Calm when undisturbed, it becomes a serious threat when pressured, using wide turns and punishing tail swings to control space around its body.

The Triceratops is one of the island’s most powerful herbivores, armed with three horns, a massive frill, and enough strength to stop a predator charge head-on. It is slow to anger but devastating once provoked, using its bulk to shove, gore, and dominate space.

Recognizable by the prominent nasal horn and brow ridges that give it its name, the Ceratosaurus is a mid-tier predator built for ambush and persistence. Slower than some rivals but devastating in close quarters, it uses its deep jaws and serrated teeth to bring down large prey.

One of the island's most agile large predators, the Dilophosaurus is defined by the twin crests running along its skull - decorative in display, dangerous in intent. Fast and opportunistic, it excels at running down weaker prey and harassing larger animals. Don't mistake its slender build for weakness; few escape a committed Dilophosaurus chase.

Among the oldest predator lineages on the island, the Herrerasaurus is a lean and relentless hunter from an era when dinosaurs had yet to dominate. Deceptively fast for its build, it uses grasping hands and a flexible lower jaw to lock onto prey and hold on. Underestimated by newcomers, respected by survivors.

Built for speed, impact, and intimidation, the Carnotaurus is a sprinting predator defined by its thick skull, bull-like horns, and powerful legs. It lacks the arm strength of other theropods, but makes up for it with explosive charges and brutal close-range bites.

A heavily built abelisaurid from the southern lineage, the Skorpiovenator is a bruiser - short arms, thick legs, and a skull reinforced for ramming and crushing. It relies on raw power and durability rather than speed, wearing down prey through repeated charges and bone-crushing bites. Named for the scorpions found near its fossils.

The Albertosaurus is a lighter, faster relative of the great tyrants, built for pursuit and power without carrying the full weight of an apex giant. It can pressure prey over distance, punish wounded animals, and bully smaller predators from kills.

The Baryonyx is a long-snouted predator built for riverbanks, wetlands, and coastal shallows. Its hooked claws and narrow jaws make it excellent at catching fish, but it is still dangerous to smaller dinosaurs that wander too close to the waterline.

Small, fast, and sharp-eyed, the Coelophysis survives through speed, numbers, and opportunity. Alone, it is fragile. In groups, it becomes a swarm of snapping jaws and nervous feet, harassing juveniles, scavenging kills, and vanishing before larger predators can answer.

The Deinosuchus is a colossal crocodilian ambush predator that turns rivers, lakes, and shorelines into death traps. Patient and nearly invisible in murky water, it waits for prey to step too close before exploding forward with crushing force.

Older than the dinosaurs themselves, the Dimetrodon carries a tall sail across its back and a low, stalking profile unlike anything else on the island. It is not built for long chases, but it excels at ambushes, short bursts, and punishing smaller prey.

The Irritator is a nimble spinosaurid that prowls mangroves, river mouths, and muddy banks in search of fish and smaller prey. Lighter than its larger relatives, it relies on mobility and quick strikes rather than brute force.

The Kryptops is a rugged predator with a blunt skull and a taste for close-range violence. Less elegant than faster hunters, it thrives as a bruiser and scavenger, pushing into kills and harassing weakened prey.

The Spinosaurus is a towering semi-aquatic predator marked by its massive sail, long jaws, and powerful swimming ability. It dominates rivers, swamps, and coastal wetlands, feeding heavily on fish but fully capable of challenging large land animals when forced.

The Suchomimus is a tall, powerful fish-eating predator with a long crocodile-like snout and heavy forelimbs. It dominates river systems and wetlands, using reach, patience, and strength to control the shoreline.

The Tyrannosaurus is the island’s heavyweight predator, built around raw bite force, thick muscle, and a skull designed to break whatever it catches. It is not the fastest hunter, but it does not need to be.

A massive pterosaur built for speed and precision, the Thalassodromeus skims coastlines and open water with its enormous blade-like crest cutting through the air. It hunts by dragging its elongated lower jaw through the water surface at low altitude, snatching fish with a snap. Territorial in the air and nearly untouchable in open sky, it becomes vulnerable only when it lands.

The Hatzegopteryx is a giant pterosaur that brings terror to open plains, beaches, and cliffside nesting grounds. On the ground, it moves with eerie confidence, using its enormous beak to threaten smaller animals. In the air, its size makes it a shadow with intent.

The Tapejara is a lightweight pterosaur known for its tall crest, agile flight, and flexible diet. It moves between cliffs, forests, and coastlines, feeding on fruit, small animals, fish, and whatever the island is willing to give.

A sleek marine reptile adapted for fast pursuit through coastal waters, the Zarafasaura patrols reefs, lagoons, and shallow seas with silent precision. Its long jaws and sharp teeth make it deadly against fish and smaller aquatic prey, while its speed lets it vanish into deeper water before danger can answer back.

The Ichthyosaurus is a fast, streamlined marine reptile built for speed, turning, and precision hunting. It darts through reefs, lagoons, and open water in pursuit of fish, relying on agility rather than brute strength.

The Kaprosuchus is a strange and aggressive crocodilian predator with long legs, raised posture, and tusk-like teeth. Unlike heavier ambush hunters, it can move surprisingly well on land, making riverbanks and jungle trails equally dangerous.

The Megalodon is a giant ocean predator built around speed, bulk, and a bite that can end a fight before it starts. It patrols deep waters and open coastlines, forcing anything aquatic to respect the blue emptiness beneath them.

The Mosasaurus rules deep water with overwhelming size, strength, and predatory instinct. Built for ambush and crushing bites, it patrols oceans, reefs, and deep channels where escape is measured in seconds.
