Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. J. Dyke et al. 2011 | The generic diagnosis provided for this taxon by Olson [4, p. 52] refers only to the cranial end of the coracoid, the only part of the skeleton available to Howard [1] for description of the Miocene plotopterid Plotopterum. Additional features unique to this taxon include the presence of marked pits (for the attachment of feather tracts) on the midshaft dorsal surface of the ulna (only known in the type of Tonsala hildegardae, Olson, 1980) and a markedly hooked and pointed processus procoracoideus. |
