"Stegosaurus was common only on well drained, dry soil"

This quote by Robert T. Bakker suggests that Stegosaurus was a dinosaur that was just found in specific types of environments. Particularly, Stegosaurus was only found in locations with well-drained, dry soil. This shows that Stegosaurus was adapted to living in dry environments, as the dry soil would have been needed for the dinosaur to endure. This might likewise recommend that Stegosaurus was a herbivore, as it would have needed to eat plants that could survive in such an environment. Additionally, the dry soil would have been essential for the dinosaur to move around, as damp soil would have been too challenging for the dinosaur to traverse. This quote offers insight into the environment that Stegosaurus was adjusted to, and the kind of environment that it would have been discovered in.
