Tratayenia can be distinguished from other megaraptorans on the basis of three autapomorphies (unique derived features) of the front portion of each dorsal vertebra, as well as a single autapomorphy of the sacrum. Tratayenia is one of the youngest known genera of megaraptorans, having lived only about 83 million years ago.
