Agrithinosaurus prairiensis is a species of non-avian therizinosaur theropod dinosaur that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, open woodlands, grasslands, shrublands, scrublands, and mountainous regions across North America to help boost biodiversity. Agrithinosaurus prairiensis is a relatively small-sized therizinosaur, measuring 2.2 meters (7.2 feet) long and weighing about 45–91 kilograms (99–201 lbs) in contrast to the advanced and giant Segnosaurus or Therizinosaurus. The neck of Agrithinosaurus prairiensis is shorter than in most therizinosaurs, whose are characterized by elongated necks adapted for high-browsing. Its feet configuration differs from more advanced therizinosaurids, having a generic three-toed feet instead of four as seen in other members. Agrithinosaurus prairiensis is a herbivore that primarily feeds on leaves, pine needles, nuts, pinecones, fruits, cycads, ferns, and horsetails. Agrithinosaurus prairiensis males are brightly colored compared with the dull brown colors of the females, and, during the breeding seasons, they inflate their neck pouches, much like frigatebirds, while "singing" deep grunting sounds to their potential mates. Once they has their full attention, they begin to shake their flamboyant crest and "clap" their massive claws together, creating a loud clacking noise. While this display is attractive to the females, it can also intimidate to younger males or overconfident predators. The conservation status of Agrithinosaurus prairiensis is Least Concern due to successful conservation efforts, the animal's wide range and its tolerance to many of the human activities.
