microptera because of these characters: coracoid--shorter but much stouter with a deeper and longer ventral portion of the facies articularis sternalis; humerus--similar in length but stouter and straighter, with a much better developed crista deltopectoralis; ulna--much longer, stouter, and straighter;
carpometacarpus --similar in length but much stouter; femur and tibiotarsus--much shorter and more slender.

This species was based on a nearly complete carpometacarpus and referred ulna and coracoids.
Miller (1931) also listed a carpometacarpus as Empidonax sp.
A mandible, humerus, carpometacarpus and coracoid, although nearly identical in configuration to T.
The proximate cause is a deformity of the distal end of the
carpometacarpus, which at times causes the primary flight feathers to droop when the wing is folded next to the body, or it can result in a dorsolateral rotation of the primaries, causing them to twist and project outward (Kear 1973, Zsivanovits et al.

Moreover, the ulnar carpal bone prevents the manus from hyperpronating during the downstroke by an interlocking mechanism with the
carpometacarpus and ulna; likewise, the radial carpal bone prevents the manus from hypersupinating during gliding and maneuvering by an interlocking mechanism with the
carpometacarpus and radius.
