Recent cladistic analyses suggest that the clade Prosauropoda, which was named by Huene in 1920 and was defined by Sereno, 1998 as all animals more closely related to Plateosaurus engelhardti than to Saltasaurus loricatus, is a synonym of Plateosauridae as both contain the same taxa.
Nylige kladestikanalyser indikerer at kladen Prosauropoda, som blev navngivet af Huene i 1920 og blev defineret af Sereno i 1998, som alle dyr der var tættere beslægtet med Plateosaurus engelhardti end med Saltasaurus loricatus, er et synonym for Plateosauridae, da begge indeholder den samme taksonomi.
