The dinosaur-like creatures are a species who are indigenous to an unnamed foggy planet. In 2009, Lt. Matthew Scott, Chloe Armstrong and Eli Wallace encountered one when they traveled through the Stargate. It immediately approached and attacked them. Eli managed to dial to another planet before it could catch them. These creatures appear to be territorial, if not aggressive, as the one seen attacked without provocation. The creature is a quadruped, with a double set of eyes and nostrils; the back of the creature is covered with multiple set of spikes. (SGU: "Lost")
