 "Hypuronector" has inversely been suggested to be aquatic due to its deep, paddle-like tail and the fact that its remains were found in an ancient lake bottom.However, several studies on its limb morphology, as well as the rather delicate tail vertebrae without evidence of extensive caudal musculature, rule out an aquatic hypothesis, and it was likely arboreal like other drepanosaurs.Perhaps more extremely, it has been suggested to be a glider or flyer, due to the limb proportions, particularly the elongated forelimbs.
