A. A. Karhu 1999 | Facies articularis acrocoracoidei claviculae lengthened mediolaterally. Acromion scapulae with cranial margin beveled laterally and crista lig. acrocoraco-acromiale well developed. Dorsal side of medial part of proc. acrococora- coideus forms high, caudally projecting crest, with mediolaterally narrow base. Facies articularis sternalis coracoidei saddle-shaped, with only medial part of crista ventralis protruding ventrad. Angulus lateralis of sternal facet projecting a little more distally than angulus medialis. Ventral part of caput humeri oriented perpendicularly to long axis of bone, whereas dorsal part oriented obliquely to it, being placed more distally relative to ventral part; distal border of caput humeri clearly outlined. Tuberculum M. tensor propatagialis pars brevis well pronounced and placed just distal to proc. supracondylaris dorsalis humeri. Tuberculum M. pronator superficialis clearly detached from tuberculum supracondylare ventrale humeri. Tuberculum supracondylare ventrale adjoins condylus ventralis humeri. Epicondylus ventralis markedly prominent ventrad. Proc. flexorius projects slightly distally beyond condylus ventralis. Tuberculum lig. collateralis ventralis ulnae relatively small and weakly protruding ventrad. Tuberculum bicipitale brachii radii with impression of M. biceps brachii. |
