Therizinosaurus is a herbivorous theropod dinosaur from the late Campanian-early Maastrichian stages of the Late Cretaceous.

In Real Life

Therizinosaurus is the largest member of the Therizinosauridae family, and was primarily an herbivore. It was 4.5 meters (15 feet) tall and 10 meters (33 feet) long, and probably weighed around 5,000 kg (11,000 lbs).

It likely used its meter (3.3 foot) long claws for multiple uses; gathering food, intimidating and attacking predators were all likely purposes of the enormous claws. It is from these claws which the specific name arises; they were initially mistaken for the claws of an enormous turtle-like diving reptile.

In The Isle

Its claw attacks can deal massive amounts of damage and it can run very quickly. It has relatively low health and can be killed by a Tyrannosaurus in three bites, so it is best to avoid them along with other apex predators.

When in combat, make sure you are facing your opponent. Your tail is the most vulnerable spot, so make sure that predators don't get to it. The best way to avoid trouble is to be intimidating, so make yourself look big to carnivores and threaten to attack if they get closer. Unfortunately, this doesn't always work since some predators are not easily intimidated by your screeching.

It is currently playable in Sandbox mode, but you can be nested in the Survival mode.

Behind The Scenes

The Therizinosaurus was modeled by Vlad Konstantinov for the now dead game The Stomping Land in the year 2014. It was then bought by Dondi for The Isle.
