In dieser Arbeit werden Vertreter aus allen fünf lebenden palaeognathen Familien (Tinamidae, Rheidae, Struthionidae, Casuariidae incl. Dromaius, Apterygidae) an der Muskulatur ihrer Hinterextremität untersucht. Besonderes Augenmerk liegt dabei auf den Muskelbefestigungen und deren Knochenmarken sowie dem Verhältnis der Muskulatur zu anderen auffälligen Knochenstrukturen (z.B. Hypotarsus). Die Befunde werden nach den Prinzipien der Phylogenetischen Systematik ausgewertet. Als Außengruppen dienen dabei Neognathae und Crocodylia. Zur Homologie der Beinmuskeln von Vögeln und Crocodylia werden neue Hypothesen aufgestellt, die bei der femoro-tibialen Muskulatur eine Abweichung von der Nomina Anatomica Avium notwendig machen. Diese Untersuchung ka...
