However, recent
cladistic analyses suggest that the Prosauropoda as traditionally defined is
paraphyletic to
sauropods.[4][5][6][7][8] Prosauropoda, as currently defined, is a
synonym of
Plateosauridae as both contain the same taxa by definition. The phylogenetic analysis of 2021 recovered Issi and Plateosaurus as the basal-most plateosaurs.[9]
The following
cladogram simplified after an analysis presented by Apaldetti and colleagues in 2011.[8]
