==Description== thumb|left|Referred humerus Given the small number of bones that are referrable to Tingmiatornis, it is difficult to infer much about the animal. However, the thickness of the cortical bone (on average, ) and the relative length of the humerus suggest that it was apparently capable of flight and likely also diving, similar to the possible hesperornithine Pasquiaornis. Tingmiatornis can be differentiated from the latter by numerous traits including larger size, a more globe-shaped dorsal condyle on the humerus, an olecranon process of the ulna that does not project outward as strongly, as well as a smaller bicipital tubercle of the ulna.
