Redescription of Eoenantiornis buhleri
Zhou, Zhonghe, Luis M. Chiappe & Fucheng Zhang, 2005. Anatomy of the Early
Eoenantiornis buhleri (Aves: Enantiornithes) from China. Canadian Journal
of Earth Sciences 42: 1331-1338.
ABSTRACT: A detailed description of the anatomy, in particular of the
skull, of Eoenantiornis is provided. This description reveals many
morphological characters previously unknown for enantiornithine birds, such
as presence of a distinct facet for the intramandibular articulation between
the dentary and postdentary bones. Eoenantiornis documents an intermediate
stage in the abbreviation of the alular digit among Ornithothoraces, which
paralleled a similar transformation within Ornithuromorpha. Our analysis
also indicates that Eoenantiornis belongs to the Euenantiornithes.
