Tenontosaurus
Herbivore
Tenontosaurus
The Vigilant Grazer

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.

Edmontosaurus
Herbivore
Edmontosaurus
The River Grazer

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.

Mantellisaurus
Herbivore
Mantellisaurus
The Forest Forager

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.

Styracosaurus
The Crowned Defender

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.

Herbivore
Ankylosaurus
The Living Fortress

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.

Herbivore
Gallimimus
The Plains Runner

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.

Herbivore
Maiasaura
The Good Mother

Known for its strong nesting behavior and herd-focused lifestyle, the Maiasaura is a social herbivore built around awareness, protection, and survival through numbers.

Herbivore
Microceratus
The Tiny Horn

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.

Herbivore
Padillasaurus
The Gentle Giant

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.

Shantungosaurus
The Colossal Grazer

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.

Ceratosaurus
Carnivore
Ceratosaurus
The Horned Predator

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.

Dilophosaurus
Carnivore
Dilophosaurus
The Twin-Crested Hunter

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.

Herrerasaurus
Carnivore
Herrerasaurus
The Ancient Killer

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.

Carnivore
Carnotaurus
The Raging Bull

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.

Skorpiovenator
The Scorpion Hunter

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.

Carnivore
Albertosaurus
The Northern Reaper

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.

Carnivore
Baryonyx
The River Hook

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.

Carnivore
Coelophysis
Hollow-Boned Raider

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.

Deinosuchus
The River Leviathan

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.

Carnivore
Dimetrodon
The Sailback Hunter

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.

Thalassodromeus
The Sea Phantom

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.
