In The Isle

Allosaurus is slightly larger and stronger than Carnotaurus and Ceratosaurus, but slower. It remains faster than apex predators like Tyrannosaurus and Giganotosaurus, though weaker overall. It's considered a balanced mid-tier predator — second only to Suchomimus among non-apex carnivores — and its main strength lies in bleed damage, which makes it deadly in hit-and-run tactics. Allosaurus was added to The Isle in Patch 0.0.0.85.

In Real Life

Allosaurus shared its ecosystem with Torvosaurus and was one of the dominant predators of the Morrison Formation — often nicknamed the 'lions of the Jurassic.' It could run between 30 and 55 km/h and likely hunted in packs or opportunistically; its habitat was semi-arid with forests and floodplains. The Cleveland-Lloyd Dinosaur Quarry contains one of the highest concentrations of Allosaurus fossils on Earth, making up 67% of the remains found there. Its jaw could open between 79° and 92°, allowing a powerful 'hatchet bite' similar to birds of prey — the teeth were serrated, ideal for slicing flesh, though the bite force itself was relatively weak. Its brain resembled that of modern crocodiles, suggesting sensitivity to low-frequency sounds. Most specimens measured around 8.5 m; the largest reached 9.7 m, with fragmentary remains suggesting individuals up to 13 m long.

Abilities

  • High bleed damage — primary kill condition is attrition, not single bites
  • Fast ambush burst (44.5 km/h vs 34.2 km/h base)
  • Among the best healing rates on the roster
  • Long hunger timer (~2h) — sustained patrols
  • Good turn radius — outmaneuvers most apex predators

Strengths & Weaknesses

Pros
  • + Balanced stats — true all-rounder
  • + High bleed damage
  • + Among the best healing rates on the roster
  • + Very good bleed recovery
  • + Short growth time
  • + Long hunger timer (~2h)
  • + Good turning radius
  • + Fast ambush speed
  • + Strong stamina and fast stamina recovery
  • + Ambush is faster than a sprinting Utahraptor
  • + Easy to find groups (popular pick)
  • + Long-lasting ambush
  • + Fast trot
  • + Skilled players can take down stronger prey (Diabloceratops, Suchomimus)
Cons
  • Mediocre sprint speed
  • Below-average bleed resistance
  • Vulnerable to 'brake-checks' (sliding by faster targets)
  • Young adults are weaker against other mid-tiers

Behavior

Versatile mid-tier predator — strong bleed, fast healing, reliable in both solo and group play. Excels in attrition fights and ambushes, punishes mid-tiers, and supports coordinated group hunts. Forgiving for beginners; lethal in skilled hands.

Growth

Total ~3 hours: Hatchling 0.5h, Juvenile 1h, Adult 2h.
