Azhdarchids will already be familiar to a great many Tet Zoo readers; indeed, in recent years they’ve become more familiar to interested people in general thanks to appearances in books, TV documentaries and films. These are the often gigantic, long-necked, long-skulled pterosaurs of the Cretaceous (and especially of the Late Cretaceous), best known for Quetzalcoatlus from Texas, a giant form in which the wingspan was about 10 metres and the total weight was somewhere round about 200-250 kg (Witton 2008, Witton & Habib 2010).
Eurazhdarcho is not a giant: it had a wingspan somewhere round about 3 m (Vremir et al. 2013), making it one of the smallest known azhdarchids. But it’s significant for several reasons, one of them being that it’s known from a comparatively large amount of material. Most azhdarchid fossils consist of isolated vertebrae and other fragmentary remains, with associated or articulated skeletons being very rare. Our description of Eurazhdarcho is based on 15 bones, all discovered together at Sebeş-Glod in Transylvania, and most of which were collected by Mátyás in 2009. We know that other bones from the same specimen were collected later on, but they’re currently inaccessible to our research group.
