Diagnosis
ReferenceDiagnosis
G. Mayr and J. L. Goedert 2016Largest species of North American Plotopteridae, about 80% the size of the Hokkaidornis
abashiriensis holotype. With the distal end of the femur of plo- topterids being subequal to the proximal width of the tarsometa- tarsus (Table 1), the holotypic tarsometatarsus (proximal width »43 mm) has a significantly larger size than expected for the unknown tarsometatarsus of Klallamornis abyssa, the distal femur of which has a width of »34 mm.
