Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles.
The featured article for Sunday, 1 November 2026, is Europejara.
Europejara is a genus of tapejarid pterosaur that lived during the Barremian age of the Early Cretaceous epoch in what is now Spain. The only known specimen was found at the Las Hoyas site of Cuenca, a location noted for its exceptional Konservat-Lagerstätte preservation. In 2012, the new genus and species Europejara olcadesorum was named based on it. The generic name refers to Europe, where it was found, and to the related genus Tapejara from what is now Brazil, while the specific name refers to the Olcades, an ancient people that lived in the region. The holotype specimen consists of an incomplete, crushed skull; the bones of the postorbital region are displaced while the mandible is almost complete.
The first tapejarid known from Europe, Europejara was also the oldest known member of that group and the oldest known toothless pterosaur at the time of its naming. A relatively small pterosaur, Europejara is estimated to have had a wingspan of around 2–4 m (6.6–13.1 ft). As a tapejarid, it had a short skull with downturned jaws and would have had two crests on the upper part of its skull connected by a keratinous structure. The genus is mainly distinguished from other tapejarids in that the dentary crest, which projected down from the front of the lower jaws, was recurved backwards, and was more developed from top to bottom than from front to back. A combination of other skull features is also used to distinguish it.
Researchers have found Europejara to be related to Brazilian tapejarids and, given its age, have used this relationship as evidence for the group's origin on the northern palaeocontinent of Laurasia. The function of tapejarid dentary crests is uncertain, but a role in aerodynamics, thermoregulation, or social behavior has been suggested. Due to the shape of their skulls and jaws, they have been considered frugivorous (fruit-eaters) and/or granivorous (seed-eaters), and the age of Europejara led its describers to suggest that tapejarids had a role in seed dispersal when angiosperms (flowering plants) first appeared. Europejara is known from the La Huérguina Formation, which represents a subtropical wetland environment.
