Species Profile - Dreadnoughtus

The mighty Dreadnoughtus was one of the largest terrestrial creatures to have ever lived. While it's known as the 'fears nothing' dinosaur, I would still keep it away from the Indominus rex.

Dreadnoughtus is a genus of sauropod dinosaur that originated from Late Cretaceous South America. One of the largest sauropod dinosaurs ever discovered, Dreadnoughtus is included in the Cretaceous Dinosaur Pack, and can be unlocked by progressing through the Science Division on Isla Tacaño, where its fossils can subsequently be excavated in the Cerro Fortaleza dig site.


Although Dreadnoughtus was not known to have been cloned by InGen, it appeared on the holographic globe in the Innovation Center. In 2018, its viable embryo was known to have been created and stored in a suitcase with embryos of other dinosaurs.[1]


One of the largest sauropods available to the Hammond Foundation, Dreadnoughtus has a long neck and slender front legs. Its base genome is a dark moss color.


One of the least social of all sauropods, Dreadnoughtus without any modifications to their social needs will live either alone, in pairs or in groups of three. They are impervious to most predators, except for the Indominus rex.

Like other sauropods, Dreadnoughtus eat exclusively from Tall Herbivore Feeders, but with the Claire's Sanctuary expansion pack, they can also eat from Tall Paleofeeders, showing a primary preference for Tree ferns and a secondary preference for Conifers and Ginkgo.


Dreadnoughtus was potentially one of the largest animals to have ever lived on land, only outclassed by fellow South American titanosaurs such as Argentinosaurus and Patagotitan. Dreadnoughtus was a surprise on its discovery in 2014, with most of the body and tail well preserved, but also parts of the skull, which is usually lost in preservation due to their flimsy nature. It is the most well preserved titanosaur found in South America, however the skeleton found was not fully grown yet, suggesting that the dinosaur could grow even larger.


Dreadnoughtus lived on a wide floodplain with other large sauropods such as Puertasaurus, ornithopods and theropods such as Orkoraptor.
