摘要	Early-diverging non-sauropodan sauropodomorphs are important groups of saurischian dinosaurs, a group that also includes theropods and the clade Sauropoda. Because of these close relations, a good understanding of the phylogenetic relationships among the non-sauropodan sauropodomorphs is key to a broader understanding of early dinosaurs. Non-sauropodan sauropodomorphs have suffered from a lack of cranial material for research, a problem this study addresses. The new specimen IVPP V 13246 consists of 14 disarticulated cranial bones from the skull roof, the palatal complex and the lower jaw, as well as well-preserved teeth. The teeth are of interest because they are more similar to those seen in sauropods than in non-sauropodan sauropodomorphs. These bones are described with characters scored and entered into a data matrix from another recent study. The analysis places IVPP V 13246 in a polytomy with Jingshanosaurus, a commonly found taxon from the same Lufeng Formation. This result does not preclude IVPP V 13246 from representing a potential new taxon and there is a great need for future research.
