Surprisingly no.
Apparently the Thecodontosaurus antiquus neotype (a dentary with teeth) is indeterminate relative to Pantydraco caducus and Saturnalia. Also, there are three humeral morphotypes in the Thecodontosaurus material, so no postcrania can be certainly assigned to the genus. One (YMP 2195) will be described by Galton (in prep.) as a new taxon, another (robust) is apparently a member of the Prosauropoda+Sauropoda clade, and the third (gracile) may belong to Thecodontosaurus and is also known from a monospecific assemblage from another locaility to be described by Yates and Benton (in prep.). Galton (in prep.) will describe the gracile and robust forms in more detail.
