The scapula is very long and slender with little curve along its length, suggesting a tall, narrow body shape. The glenoid (shoulder joint) faces down and slightly back, suggesting upright forelimbs. The humerus and ulna are both very long and slender, and the ulna is noticeably longer than the humerus. They are similarly proportioned to those of the contemporary long-legged crocodylomorph Terrestrisuchus but differs in having a rounded deltopectoral crest at the very top of the humerus. A pelvis that may belong to Aenigmaspina is lightly built, with slender pubes and ischia and an ilium with a long, pointed backwards process and deep hip socket (acetabulum).
