In "The Lost World" by Michael Crichton, the author vividly describes the presence of parasaur dinosaurs, emphasizing the unique characteristics of these creatures. Each parasaur is noted for producing large mounds of straw-colored waste, which creates an impressive visual. This depiction highlights their size and the substantial impact they have on their environment.

Additionally, the narrative includes the low trumpeting sounds emitted by the herd, further illustrating their social behaviors. The mention of methane-rich flatus adds a humorous yet informative aspect to the scene, showcasing the biological realities of these large animals and their ecological influence.
