Elanodactylus prolatus NGMC 90-07-1 (Andres and Ji 2008, Zhou 2009) Early Cretaceous, ~2.5 m wingspan, was originally and subsequently considered a ctenochasmatid. Here Elanodactylus nests within the genus Germanodactylus. Derived from a sister to the BMM specimen of Germanodactylus, Elanodactylus was a phylogenetic predecessor to the SMNK-PAL 6592 specimen of Germanodactylus.

Much larger overall than and distinct from the BMM specimen, the cervicals of NGMC 90-07-1 were elongated. The sternal complex had four sharp corners. The scapulocoracoid was more robust. The deltopectoral crest of the humerus was shorter. The radius and ulna were more robust. The metacarpus was much shorter. Manual 4.1 was shorter than m4.2 or m4.3.

Distinct from NGMC 90-07-1, the sternal complex of LPM-R00078 developed lateral processes. The humerus was relatively smaller. Fingers I-III were smaller. Manual 4.1 was further shortened and manual 4.4 was elongated. Distinct from No. 61, the posterior process of the ilium was shortened. The ischium was shortened. The posterior process of the prepubis was elongated. The pedal digits were shorter and the unguals were more alike in size.

NGMC 90-07-1 and LPM-R00078 appear to have been congeneric, but not conspecific.
