What is the effect of stegosaurus?

Stegosaurus was a large herbivore that probably ate mosses, ferns, horsetails, cycads, and conifers that grew within three feet of the forest floor. Like other large herbivores, the role of Stegosaurus in its ecosystem was to prevent plant overgrowth. They also helped to recycle nutrients via their urea and feces. Last but not least, they provided food for animals farther up the food chain, such as Allosaurus, Torvosaurus, and Ceratosaurus.
