Parasaurs can be set on turret mode and will look for enemy players or tames and alert you of them. This can be very useful if you have many of them around the entire map. A message wil then pop up saying:

“(Name of Dino) detected an enemy” and a red dot will appear at their location. You can name your Parasaur something like “Redwoods” or “beach” so you will now where the enemy is even at long distances.
