Based on its morphology Wang et al. (
2013) showed that Yunganglong was more derived than the basal hadrosauriform Iguanodon but more primitive than the hadrosaurids, such as the well known Edmontosaurus and Corythosaurus.
To further explore the phylogenetic position of Y. datongensis among hadrosauriforms, Wang et al. (
2013) used a modified version of the data matrix first presented by Sues and Averianov (2009).
Nanyangosaurus, Shuangmiaosaurus, and Yunganglong were added to the matrix, and two character codings were modified.
In the strict consensus tree, Yunganglong was recovered as more advanced than Probactrosaurus, in an unresolved polytomy with Jintasaurus, Protohadros, Nanyangosaurus, Shuangmiaosaurus, Levnesovia, Bactrosaurus, Tanius, Telmatosaurus and the clade formed by Aralosaurus and Hadrosauridae.
The 50% majority rule tree resolved its phylogenetic position further, as shown in the cladogram below.
