Procoracoid identity issues

[alex-dececchi]

According to Vickaryous and Hall 2006 the identity of the reptilian "coracoid" is not what has been previously suggested. They postulate that of the two ancestral "coracoid" elements (termed here the procoraoid and the metacoracoid) that it is the meta, not the procoracoid, that makes up the majority of the "coracoid" element in modern reptiles (similar to the state of affairs in modern mammals). I suggest we contact Brian Hall and have a discussion on the nomenclature of this element. I think that we change the terminology of the "coracoid bone" to have the preferred term read the "procoracoid" and "metacoracoid" respectively. This would require users to specify which element they wish to select when they annotate.
