       The most noteworthy feature of Coelurosauravus are the dermal ossicles, creating thin strands of bone that extended from the flanks and supported a gliding wing. This may have provided a limited flight capability over short distances by jumping from a high point and steering itself by twisting towards a lower spot as it fell down.
       In Coelurosauravus the back of the skull also features a frill similar to the kind seen in later ceratopsian dinosaurs. This is likely to have been a display feature as opposed to an aerodynamic one.
       It is thought that Coelurosauravus would have lived within the tree canopy, gliding from branch to branch in a similar manner as a flying squirrel. This way it could quickly cover a number of trees in a shorter space of time than that required to climb down and up each individual tree.
       These gliding membranes may also have been a display structure for attracting mates and/or dominance displays with rivals. They may have also formed a threat display by being quickly opened to startle predators when they got too close, allowing Coelurosauravus a chance to escape.
