Eurazhdarcho is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous period in what is now Romania, about 69 million years ago.

Starting in 2009, pterosaur fossil remains were unearthed in a layer of the Sebeș Formation in Lancrăm, southwestern Transylvania by paleontologist Mátyás Vremir.

With extrapolations from the comparisons of cervical vertebrae and wingbones of Eurazhdarcho with those of the related azhdarchid Zhejiangopterus from China, Vremir and colleagues would estimate a wingspan not surpassing 3 m (9 ft 10 in).

In 2009, Romanian paleontologist Mátyás Vremir uncovered the remains of a pterosaur at the SbG-B site of the Sebeș Formation in Lancrăm, near Sebeș-Glod in southwestern Transylvania, Romania.

[1] In 2013, Vremir, along with paleontologists Alexander Kellner, Darren Naish, and Gareth Dyke named and described a new genus and type species, Eurazhdarcho langendorfensis.

[1] The holotype specimen, EME VP 312, was found in a layer of the Sebeș Formation dating from the upper Early Maastrichtian, about 69 million years old.

Generally, the quality of the bones is poor, with much of the outer cortex broken or eroded and internal structures present as impressions of natural molds.

Vremir and colleagues considered a juvenile identity for Eurazhdarcho with respect to Hatzegopteryx to be unlikely because the much smaller EME VP 312 seems to represent an adult individual.

The necks of the prezygapophyses, the front joint processes, are well-developed and elongated, obliquely pointing forwards and outwards under an angle of 30 degrees with the long axis of the vertebra.

The area where Eurazhdarcho was found, in the Upper Cretaceous was localized on the Hațeg Island, part of the prehistoric European archipelago in the ancient Tethys Sea.

The SbG-B site, though encompassing a surface of just 200 m2 (2,200 sq ft), has yielded several distinct animal species, among which are the turtle Kallokibotion bajazidi, the hadrosaur Telmatosaurus and the titanosaur Magyarosaurus.
