Eurazhdarcho

Eurazhdarcho is a genus of azhdarchid pterosaur from the Late Cretaceous period (Maastrichtian stage) of what is now the Transylvanian Basin of Romania. Its fossil remains dated back 69 million years ago. In 2009, Mátyás Vremir at Lancrăm near Sebeş-Glod in Transylvania at the SbG-B site uncovered the remains of a pterosaur. He donated these to the Erdélyi Múzeum, of the Societății Muzeului Ardelean (Transylvanian Museum Society). Subsequent excavations by Vremir discovered additional bones of the same individual animal and were added by him to the collection of the Babeș-Bolyai University. In 2013, Vremir, Alexander Wilhelm Armin Kellner, Darren Naish, and Gareth Dyke named and described the type species Eurazhdarcho langendorfensis. The generic name combines the name of Europe with that of the related form Azhdarcho. The specific name refers to Langendorf, the name of Lancrǎm in the language of the German ethnic minority in Romania. The article appeared in the electronic journal PLoS ONE without an accompanying printed version; it nevertheless validly names the taxon under the new rules of the ICZN. The holotype, EME VP 312, was found in a layer of the Sebeş Formation dating from the upper Early Maastrichtian, about 69 million years old. It consists of a partial skeleton lacking the skull. It includes three neck vertebrae among which the almost complete third and the fourth; the third and fourth right metacarpal; the upper part of the first phalanx of the wing finger; the lower part of the second phalanx; a lower phalanx of one of the other fingers and a number of undetermined fragments. The Babeș-Bolyai University material is included within this enumeration and is not indicated by a separate inventory number. 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. The fossils have not been completely flattened, preserving three-dimensionality, but compression has caused some distortion.
