Massopoda is a clade of sauropodomorph dinosaurs which lived during the Late Triassic to Late Cretaceous epochs. It was named by paleontologist of the University of the Witwatersrand in 2007. Massopoda is a stem-based taxon, defined as all animals more closely related to Saltasaurus loricatus than to Plateosaurus engelhardti.[4]

The name Massopoda, from Latin massa 'lump'; from Ancient Greek πους (pous) 'foot', is also contraction of Massospondylidae and Sauropoda, two disparate taxa in the clade.

Classification[]

Yates assigned the Massopoda to Plateosauria. Within the clade, he assigned the families Massospondylidae (which includes the relatively well-known dinosaur Massospondylus) and Riojasauridae (which includes Riojasaurus) as well as the Sauropoda.[5]
