Acrocanthosaurus

***Acrocanthosaurus sciifii*** (name meaning "SciiFii's high-spined lizard") is a species of Carcharodontosaurid theropod dinosaur that originally lived in what is now North America during the Aptian and early Albian stages of the Early Cretaceous as an extinct species, *Acrocanthosaurus atokensis*, and was once extinct, but has since been brought back from extinction by SciiFii, and, unlike most predatory non-avian dinosaurs, was intentionally introduced to the modern open woodlands and grasslands of North America to help boost biodiversity. *Acrocanthosaurus sciifii* is a bipedal predator and, as the name suggests, it is known for the high neural spines on many of its vertebrae, which supports a ridge of muscle over the animal's neck, back, and hips. *Acrocanthosaurus sciifii* is one of the largest theropods, reaching 11.5 meters (38 ft) in length, and weighing up to 6.2 metric tons (6.8 short tons). Due to its massive size, its body is mostly scaly and featherless to reduce the chance of overheating, but it has some feather patches covering the top of its head, neck, and back. *Acrocanthosaurus sciifii* is an apex predator, but does not hunt large mammals (humans, elephants, cows, etc), instead it only preys large feral sauropods and ornithopods such as, for example, Brachylophosaurus and Ouranosaurus, most likely a result of SciiFii modifying its diet so it wouldn't hunt people or other large land mammals. In order to hunt ornithopods and sauropods, it uses its strong clawed arms and sharp teeth in order to slice through flesh. The brain of an *Acrocanthosaurus sciifii* has an intelligence between those of an alligator and those of a tiger, making it smart for a non-avian predator. It is also a scavenger that can also steal kills from much smaller predators such as bears, wolves, big cats, and among other carnivores, by making loud rumble noises comparable to the audible alligator rumbles (it doesn't roar unlike in pop culture) and waving its arms as if it were clapping, but if those don't work it can swipe its clawed arms at the predator(s), potentially killing the predator(s) and steal its/their kills. It is a solitary animal in most of its life, except during breeding seasons or if it's a caring/protective mother of its hatchlings. The *Acrocanthosaurus sciifii* mothers builds a large mound and it takes around 6 months of gestation period until the mothers lay around 30-50 eggs. Most eggs are eaten by many egg-eating animals such as rats, mice, raccoons, foxes, etc, but around 5-15 eggs survive and the babies inside hatch and are cared for by their mothers until they are juveniles, when they must fend for themselves, and they can live to be around 30-40 years in their lifetime. Despite being massive predators, the *Acrocanthosaurus sciifii* is completely docile and tame towards humans and domestic animals, due to SciiFii's genetic tampering, allowing people to tolerate the presence of *Acrocanthosaurus sciifii*. The conservation status of the *Acrocanthosaurus sciifii* is **Least Concern** due to successful conservation efforts, the wide range of the *Acrocanthosaurus sciifii*, and its tolerance to most of human activities, including being able to adapt to life in the cities and suburbs (thanks to the abundance of feral ornithopods in cities/suburbs of North America).
