Genus - Typespecies
PKNU-G.102-109, the material consists of seven incomplete cervical vertebrae, a nearly complete dorsal centrum, a cervical rib, an incomplete dorsal rib, a complete chevron, a part of clavicle (?) amd other fragments of bones. These bones were collected from the same quarry and same level, and they should be assigned to one individual. The morphologies of the nearly complete cervical and mid-dorsal vertebrae suggest a close affinity of this dinosaur, Pukyongosaurus millenniumi gen. et sp. nov., with the family Euhelopodidae.
Derivation of generic name is from Pukyong National University, where the latter two coauthors are employed. Specific name commemorates \\\\\\\"the year 2000, a new millennium.\\\\\\\"
Pukyongosaurus is classified as a sister group of Euhelopus in [Somphospondyli].
Diagnosis of genus (as for the type species)
