Diagnosis
ReferenceDiagnosis
K. -Q. Gao and D. T. Ksepka 2008The genus is diagnosed by derived character states including an elongated neck consisting of 19–24 cervical vertebrae and subequal length of the third and fourth metatarsals. Because the skull of Shokawa remains almost entirely unknown, it is uncertain which features of the skull diagnose Hyphalosaurus and which are shared between the two taxa
