Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Allain et al. 2004 | A primitive sauropod displaying the following autapomorphies: a thin bony plate extending from posterodorsal margin of postorbital; distal chevrons forked with unfused anterior and posterior processes, prominent crest on the lateral surface of the proximal end of the fibula. Moreover, Tazoudasaurus exhibits a unique combination of sauropod synapomorphies (see below) and sauropodomorph symplesiomorphies including: 20 dentary teeth with denticulate crown margins; anterior end of the dentary only slightly expanded relative to depth of dentary at midlength (Fig. 2a–b); dentaries meet in a V-shaped symphysis; posterior fossa absent on quadrate (Fig. 2c); lesser trochanter present laterally on femur; flat pubic apron; plantar surface of pedal unguals II–III flattened (Fig. 2m). | |
| R. Allain and N. Aquesbi 2008 | A primitive sauropod displaying the following autapomorphies: thin bony plate extending from the posterodorsal margin of the postorbital; vertically oriented elliptical foramen magnum; absence of cpol on the presacral vertebrae; distal chevrons bridged proximally and forked distally with unfused anterior and posterior processes; phalangeal formula of the manus is 2-3-2-2-2; developed medial bump on the anterior surface of the proximal end of the metatarsal IV. |
