Dreadnoughtus (NuGen)

Dreadnoughtus tyrannus (name meaning "tyrant fears nothing") is a species of titanosaurian sauropod dinosaur that originally lived in what is now the Cerro Fortaleza Formation in Santa Cruz Province, Argentina in the Upper Cretaceous (Campanian to Maastrichtian; approximately 84–66 Ma) as an extinct species, Dreadnoughtus schrani, and was once extinct, but has since been brought back from extinction by NuGen, possibly as a form of competition with SciiFii in the race to recreate extinct animals, and, unlike the original species or SciiFii's recreation, introduced throughout the modern open woodlands, grasslands, shrublands, and scrublands across North America to help boost biodiversity. Dreadnoughtus tyrannus is among the largest terrestrial vertebrates, possessing one of the greatest mass of any land animal, with the average weight of about 49 tons (108,027 lbs) and the length of 26 meters (85 feet). Unlike SciiFii's Dreadnoughtus meridionali, Dreadnoughtus tyrannus has a more robust body build, a slightly shorter neck, smaller body amour, and, uniquely among recreated sauropods, the male Dreadnoughtus tyrannus has inflatable, orange-colored air sacs running down its neck that are used for communication and display. Dreadnoughtus tyrannus is a herbivore like most advanced sauropods, feeding mainly on fruits and leaves of ferns, cycads, horsetails, conifers, and among other evergreen trees, but can sometimes feed on nuts. It is a social herd-dwelling animal, living in groups up to around 30-75 individuals at a time in most cases, but can occasionally live in herds as much as around 150 if there's enough space and food for them. The females live in herds throughout almost all their lives, while males live in solitary lives, in a manner similar to elephants, and during mating seasons, males visit nearby herds and clash with other males through series of bites and shoving other males with their front limbs until one backs down, that's when a winning male Dreadnoughtus tyrannus gets a right to mate with any of the herds' females. Like the closely related SciiFii's Dreadnoughtus meridionali, in just 2 or 3 months, Dreadnoughtus tyrannus lay between 15 and 40 eggs, which hatch between 1 and 2 months. The young are immediately cared for as soon as they hatch, and they remain with the adults, with the exception of subadult males, which leave the herds when they reach sexual maturity. The conservation status of Dreadnoughtus tyrannus is Least Concern due to successful conservation efforts and the animal's wide range.
