Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. L. Olson 1980 | Distinguished from Plotopterum by having coracoid with (I) glenoid facet more elongate, with margins not as distinctly raised above shaft, and (2) sternal margin not sinuate; (3) furcular facet projecting farther ventrad; (4) coracohumeral surface relatively longer and narrower. | |
| G. J. Dyke et al. 2011 | The diagnosis provided for this taxon by Olson ([4], p. 52) is the same for the genus. Additional features, besides characters mentioned for the genus, are as follows: fossa m. brachialis of humerus deep and rounded in caudal view; margin between crista brachialis and humeral shaft greater than 90 degrees; sulcus ligamentous transversus does not reach the impressio coracobrachialis; processus extensorius of carpometacarpus rounded, blunt and upturned; fossa infratrochlearis shallow above processus pisiformis; cranial margin between trochlea carpalis and processus pisiformis very wide. |
