 ABSTRACT
Fragmentary cervical vertebral elements of a gigantic pterosaur are described from the upper Campanian–Maastrichtian Nemegt Formation in the Gobi Desert. With an estimated width of a posterior centrum across the postexapophyses of 198 mm, this taxon represents one of the largest pterosaurs currently known. This is the first discovery of a pterosaur from the Nemegt Formation, adding further evidence that gigantic pterosaurs were widely distributed in Eurasia and North America during the latest Cretaceous.

PTERODACTYLOIDEA Plieninger, 1901
ORNITHOCHEIROIDEA Seeley, 1891 
?AZHDARCHIDAE Nessov, 1984 

Gen. et sp. indet.

Locality: Gurilin Tsav, western Gobi Desert, Mongolia.
 Formation/Age: Nemegt Formation, Upper Cretaceous (upper Campanian–lower Maastrichtian to Maastrichtian). 

DESCRIPTION 
Three vertebral elements, one centrum, and two fragmentary neural arches (MPC-D 100/116, 100/117, and 100/118), were found in close proximity to one another in the same horizon and were thus presumably derived from a single individual.
