Europejara olcadesorum Vullo et al., 2012 |
|
Europejara is a genus of tapejarid pterosaur from the Early Cretaceous of Spain.
In 2012, the type species Europejara olcadesorum was named and described by Romain Vullo, Jesús Marugán-Lobón, Alexander Kellner, Angela Buscalioni, Bernard Gomez, Montserrat de la Fuente and José Moratalla. The generic name combines the names of Europe and the related genus Tapejara, in reference to the fact that Europejara is the first tapejarid found in that continent. The specific name refers to the Olcades, the Celtiberic tribe inhabiting the region of Cuenca, the location of the find, in Antiquity.
The holotype, MCCM-LH 9413, was uncovered at the Las Hoyas site in a chalkstone layer of the Calizas de La Huergina Formation dating from the late Barremian. It consists of a partial skull with lower jaws, compressed on a slab and counterslab. Two elements of the hyoid are present also. The skull has been vertically crushed, the lower jaws horizontally. The specimen was prepared by Mercedes Llandres Serrano, and is part of the Las Hoyas collection of the Museo de las Ciencias de Castilla–La Mancha.
Europejara is a relatively small form with an estimated wingspan of two metres. The jaws are toothless and the lower jaws bear a large downwards pointing crest.
The describers established three autapomorphies, unique derived traits. The crest on the lower jaws is curved to the back. The crest is deeper than its base, measured from the front to the back, is wide. The crest is four times deeper than the back of the jaw. Two other diagnostic traits were indicated: the inner side of the lower jaw is thickened, causing a convex curvature; the inner side shows some shallow, but well-demarcated, depressions.
