Metriacanthosaurus is a species of dinosaur in Additional Creatures.


Metriacanthosaurus is a species of medium-sized theropod dinosaur often found on the beaches of island arks. Arguably the beach’s top predator, one would expect Metriacanthosaurus to be a danger to new survivors. Well…it isn’t in reality. Metriacanthosaurus seems to lack the ferocious behavior and bloodlust of other ark predators, becoming docile for a time after consuming a meal. As such, while Metriacanthosaurus is indeed a threat, it is less of one than a survivor may think, as a sated Metriacanthosaurus is completely fine with being approached- so long as it is not hungry! Smart survivors will take the opportunity to try and befriend a powerful partner and ally for their beginning and middle of their adventure.

The Metriacanthosaurus has a "hunger" mechanic, where once it has feasted on a corpse it will become neutral towards players and creatures. This pacified state is indicated by a green aura around its head, which is when it is susceptible to passive taming.
