Diagnosis
ReferenceDiagnosis
D. T. Ksepka et al. 2023Plotornis archaeonautes differs from Plotornis delfortrii in the more prox- imodistally elongated tuberculum supracondylare ventrale, shallower fossa m. brachialis, and less ventrally deflected proximal tip of the condylus dorsalis, and differs from Plotor- nis graculoides in having a more weakly developed tubercle at the distal end of the crista deltopectoralis, a less widened proximal end of the tarsometatarsus (relative to shaft width), and a more distal origin of the crista plantaris lateralis of the tarsometatarsus.
