Diagnosis
ReferenceDiagnosis
F. L. Agnolin and A. G. Martinelli 2009Alamitornis is diagnosed on the basis of the following autapomorphies: 1) humeral shaft very thin mediolateraly distal to proximal end, 2) deltopectoral crest proximodistally abbreviated and subtriangular in contour, and 3) inflated humeral head placed well proximally with respect to the internal tuberosity.
