The cloacal is said to be an all-purpose opening that the dinosaurs use for breeding, urination, and defecation. According to the story by Bristol.ac.uk, Although most mammals usually have different openings for these different functions, most of the vertebrate animals actually possess a cloaca. Although most people know dinosaurs and their own appearance as usually feathered, horned, and scaly creatures as well as which colors they were, there aren't many findings regarding their vents and how they look like.
