A new sauropodomorph dinosaur from the Lower Jurassic Fengjiahe Formation of Dali of Yunnan Province, China

Early-diverging sauropodomorph dinosaurs are abundant in the Lower Jurassic Lufeng Formation of Lufeng area of Yunnan Province, southwestern China. However, the fossil records of this group remain relatively scarce in other regions of China. Here we describe a new sauropodomorph, Xiangyunloong fengming gen. et sp. nov., based on recently collected material from the Lower Jurassic Fengjiahe Formation of Xiangyun County of Dali Bai Autonomous Prefecture of Yunnan Province, which is about 200 km west to the Lufeng dinosaur fossil sites. Xiangyunloong can be diagnosed by several unique features such as lateral expansion developed at the middle region of the dorsal end of cervical neural spines, heightened hyposphene of dorsal vertebrae, and ilium with anteroposteriorly reduced but laterally and ventrally flaring supracetabular crest. Phylogenetic analysis recovers Xiangyunloong at a position between Massospondylidae and Sauropodiformes and within an unresolved clade together with Xingxiulon..., , # A new sauropodomorph dinosaur from the Lower Jurassic Fengjiahe Formation of Dali of Yunnan Province, China

## Description of the data and file structure

##### **File:** Supplementary_dataset.tnt

**Description:** This dataset comprises 82 taxa (including mostly early-diverging sauropodomorphs and some outgroups) and 398 characters. It contains the codings of the new specimen, which is used for the phylogenetic analysis in this paper. The dataset can be conducted in TNT 1.5 (Goloboff and Catalano, 2016) using the following procedures: (1) Import the .tnt file in TNT 1.5. (2) The maximum number of trees is set at 10000. (3) Choose the Traditional search; the number of replicates is set at 1000, and the number of trees to save per replication is set to 10. (4) Click \"Search\" to run the analysis.
