Did ankylosaurus have water in its body or did it have to find water?

All animals have water in their body, not only in the blood but in the cytoplasm, or jelly-like filling, of each and every cell. However, all animals lose some water every day, not just to urination but also to evaporation through its breath. To replenish lost water, nearly all animals drink. Ankylosaurus lived in an environment where water was usually available, so they most likely drank regularly. One of Ankylosaurus's relatives, Sachania, lived in the Gobi Desert of Asia, and it does show adaptations for water conservation. Specifically, it appears to have had glands next to its nostrils that would have allowed it to expel excess salt without having to urinate, thus minimizing how often it urinated and also conserving water. Even Sachania, though, probably didn't get all of its water from food and had to drink every few days at least.
