I recommend using Yates and Kitching's newest tree, with some added data
from Yates (2003), Galton (2001) and others-
Sauropodomorpha
|--Saturnalia
`--+--Thecodontosaurus
   `--+--Efraasia
      `--+--Prosauropoda
         |  `--+--Riojasaurus
         |     `--Plateosauria
         |        `--+--Plateosauridae
         |           |  |--Plateosaurus
         |           |  `--Sellosaurus
         |           `--Massospondylidae
         |              `--+--Coloradisaurus
         |                 `--+--Lufengosaurus
         |                    `--+--Massospondylus
         |                       `--+--Yunannosaurus
         |                          `?-Jingshanosaurus
         `--Sauropoda
            |--Euskelosaurus
            `--+--Anchisaurus (incl. Ammosaurus)
               `--+--Melanorosauridae
                  |  |?-Camelotia
                  |  `--Melanorosaurus
                  `--+--Antetonitrus
                     |-*Blikanosaurus
                     |?*Lessemsaurus
                     `--+--Isanosaurus
                        `--+--Kotasaurus
                           `--+--Vulcanodon
                              `--Eusauropoda
Properly named taxa of uncertain affinity include Azendohsaurus,
Gongxianosaurus, Kunmingosaurus, Mussaurus, Ohmdenosaurus, Ruehleia,
Yimenosaurus and Zizhongosaurus.
